New Generation Ring Coil Tester: LCR-Reader-MPA with Coil Test Unit
A Popular All-in-one Digital Multimeter from Siborg now has the option of performing ring test with a new accessory
LCR-Reader-MPA from Siborg Systems Inc. is an All-in-One Digital Multimeter that offers quick, high accuracy testing for SMT with little or no set-up between measurements. The device has recently added another test option: a Ring Coil Test.
The LCR-Reader-MPA is a lightweight multimeter with 0.1% basic accuracy and a wide range of features including 100 kHz test signal, AC/DC current/voltage testing, Oscilloscope mode, pulse/signal/duty testing, super cap tests and more. The MPA can automatically determine the type of component and best test parameters when set to Auto mode; this is exceptionally helpful when testing unlabeled components. All measurement values, including the main impedance value, secondary values (ESR), component type, and test frequency are made available almost instantly on the LCD display in the device.
Basic inductor or coil tests can be done using any LCR meter, such as LCR-Reader. When testing, if the device shows any reading (or continuity) this shows that the coil winding is not destroyed. Many times, the reading of the coil may show a slight deviation in values that is only detectable by knowing the exact original values of R or L. If there is one or a few turns of the winding that have short, the values would only show a slight variation.
A much more accurate method of finding short turns in a coil is by using the Ring Test method. This method is a tried-and-true method of repairing old-style audio-video equipment that employ flybacks, motors, deflection yoke windings, motors, main transformers, chopper transformers, VCR video and other magnetic heads, and other coils, transformers or inductors.
This method is based on the theory that if a faulty coil or transformer has shorted turn(s) in one of the coils, the Q-factor of the transformer is drastically redacted. When an impulse is applied, a faulty transformer will resonate with a highly damped oscillation while a good one will decay gradually.
When a high quality capacitor is connected across one winding of the investigated device and a pulse is applied to the parallel resonant circuit ,the waveform across the resonant circuit will produce a decaying oscillation, with at least a few cycles if the coil is good. The oscillations will be strongly damped and only complete 1-2 cycles if there is a shorted turn in any of the magnetically coupled coils of the device. A short turn can also be applied, if possible, to compare the behavior with and without the short turn; if there is no change, there must be a shorted turn in at least one coil. Experience and comparison with a known good device will tell you what to expect.
The Ring Coil Tester for LCR-Reader-MPA is connected through the micro-USB port on the device and connects to a coil by the hook connectors.
The MPA device must be set to “winding turns” in the menu. When set, the screen will show the excitation response on the display. Figure 1 shows the difference between testing a working coil (left) and one with a short turn around the coil (right). The example shows the dramatic difference of the display; when a shorted turn is connected, the display shows a significantly higher dissipation factor and therefore a fewer number of oscillations following the impulse on the coil.
LCR-Reader-MPA was introduced in 2019 as a more accurate and versatile option to the LCR-Reader multimeters. The MPA offers more features than any LCR-Reader or Smart Tweezers device, including the aforementioned oscilloscope mode, which hasnt been included on any of Siborg’s devices after Smart Tweezers ST-1.
Recently, Siborg has begun offering a Low-Frequency model of LCR-Reader-MPA and a Bluetooth enabled model. The Bluetooth model connects to PC and Android devices to remotely record measurement values in real time.
MPA Features:
Test Frequency including 100, 120 Hz, 1, 10, 20, 30, 40, 50, 60, 75 and 100 kHz
0.1% basic accuracy

Epson has launched the S1C31D51, a 32-bit ARM Cortex-M0+ MCU that has integrated hardware that is able to play sound on speakers and buzzers. by Ally Winning @ eenewsembedded.com
Epson will manufacture 200,000 of the new controllers each month.
The ARM Cortex-M0+ processor features a dedicated hardware processor that is capable of producing 2-channel sound on the single MCU chip. This hardware allows the output of voice guidance sounds, such as error and warning messages on a buzzer instead of a speaker. Buzzer sound output performance can often be very poor with low volume and limited bandwidth. S1C31D51 improves that buzzer performance with a combination of software and hardware.
The dedicated “HW processor” support of the MCU allows two special features.
Initially, the HW processor plays the sound without the need for CPU resources, allowing those resources to be used by other processes – even during sound playback. Epson employs a high data compression algorithm (16 kbps @ 15.625 kHz) to cut the size of sound data memory. This makes it possible to use a large amount of sound data, or sound data in multiple languages. Epson’s also offers its own Voice Creation PC Tool. The software tool is free of charge for customers and provides a simple development environment to create sound data for 12 languages without studio recording. Existing WAV data can also be used.
Secondly, the MCU has an integrated self-memory check function that detects failures in built-in RAM, built-in Flash, and external QSPI-Flash memories without the use of CPU resources.
The 1 S1C31D51 evaluation board includes the TDK Corporation’s electromagnetic and piezoelectric buzzer. The board allows quick audio testing along with the preset demonstration.
The HW Processor dedicated hardware block executes a variety of functions without using CPU resources:
2-channel mixing sound (for playing background music + voice)
Voice speed conversion (playback speed adjustable in 5% increments between 75% and 125%)
A sampling rate of 15.625 kHz, which is high enough for background music as well as voice.
High-compression voice decoding algorithm with high sound quality (16/24/32/40 kbps)
Last time we examined how to program the STM8s microcontroller using the Arduino IDE. This way may work for developers who are familiar with the IDE and want to build quickly, and professional projects, but there are more ways to get the same result. Thus for today’s tutorial, we are going to examine how to use traditional tools like the Cosmic C compiler along with STVD to program the STM8s microcontrollers.
There are several members of the STM8s microcontroller out there but for this tutorial, we will work with the STM8S103F3P6 microcontroller which is one of the cheapest, and most popular member of the family. The popularity of the STM8S103F3P6 makes it a perfect microcontroller for beginners as you can easily find support for it across several forums on the internet.
For easy prototyping, we will use the STM8sBlue development board which is essentially a breakout board for the STM8S103F3P6 MCU with a USB interface, breadboard compatibility, and a few other components to facilitate the development of prototypes for projects based on the MCU.
In addition to the STM8sBlue development board, we will need the ST-LINK programmer, preferably the ST-LINK v2 programmer. It will be used to upload firmware from the PC to the microcontroller.
Our goals for today’s tutorial will be to examine how to set up the tools, and for a demo, we will flash the microcontroller with the hardware hello world LED blink example.
Ready? Let’s go
Required Components
The components required to replicate and follow this project includes:
The STM8sBlue and the ST-Link programmer can be bought from the attached links, while others can be easily obtained from your favorite electronics component store. The resistor and LED are only important if you will prefer to use an LED other than the one onboard the STM8sBlue.
Schematics
Asides schematics for folks who will not be using the onboard LED, the only schematics associated with this project is for the connection between the STM8sblue and the ST-Link V2 programmer. Connect both of them as shown in the schematics below:
Schematics
A pin-pin map showing how the ST-Link V2 is connected to the dev board is also provided below to make the connection easy to follow.
With this done, we can now proceed to set up the software side of the project.
Install the Cosmic C compiler and STVD
To program the microcontroller, we need an IDE and a compiler. As mentioned during the introduction, we will use the Cosmic C compiler and the ST Visual Develop (STVD) IDE. Unfortunately, both software is only available in the Windows OS version so you will need a windows based machine or a partition to install and use them.
Head over to Cosmic and ST websites and download the software. Both software is free to use and will only require you to sign up on the websites to download.
With both software downloaded, run the installation, following the on-screen instructions displayed by the setup wizard. The STVD IDE should install without a fuss, but the Cosmic C compiler will request that you get a free license key, with a prompt that asks for your email address.
The prompt is displayed after a readme file that contains guidelines on use, is closed.
Fill the information requested by the prompt, select the “On the Web” option (if you are connected to the internet), and click on done. This should launch a webpage where you will be required to enter your email address again if not auto-filled. With these complete, you should get a license request processed notification, and receive the license key in your email, a few minutes after submitting the request. Due to spam algorithms, the license email may be “quarantined” in the spam section of your email box. Make sure also to check there.
With the license file received, follow the installation instruction, and copy the license.lic file to the “license” sub-folder of the COSMIC installation folder on your computer. In my case the license sub-folder was located at this path: “C:\Program Files (x86)\COSMIC\FSE_Compilers\CXSTM8\License“.
With this done, both software should now be fully installed and ready for use.
One other thing we need, that is probably better to also get at this stage, is the Standard Peripheral Library for the STM8S103F3P6 microcontroller. The library can be downloaded from ST’s website, but for simplicity and ease of use, this nicely modified library by Circuit Digest’s Aswinth Raj might be a better version.
With all these in place, we can now proceed to use these tools to develop the code for our project.
Code
To write the firmware, we need to create a new project specifying the microcontroller for which the firmware is to be developed and the destination folder where all project files will be store. Follow the steps below to do this:
Start by opening STVD and select File -> WorkSpace, in the pop-up, select “New Workspace” and enter the Project name and path where the program should be saved. I am naming my program BareMinimum and saving it in a folder on the desktop. Click OK and you will get the New Project dialog box as shown below.
1. Open the Installed ST Visual Develop and go to File -> “New Workspace” to create a new workspace.
2. On the resulting pop-up box, select the “Create a Workspace and Project” option highlighted in the image below.
3. On the next window, enter your preferred workspace name. I will be calling this “newproj” and will save it in the default location. Click OK when done.
4. The next window will require you to provide a project filename, preferred storage location, the toolchain to be used, and the root address to the toolchain. For me, the project name will be newproj, and the directory will be the default. We will use the Cosmic C compiler so you should set the toolchain as STM8 Cosmic and the toolchain root should be the path where your Cosmic compiler was installed. The default path address is “C:\Program Files (x86)\COSMIC\FSE_Compilers\CXSTM8” and should also be the path on your machine if it was not changed during installation. You can also use the folder button to navigate to the CXSTM8 folder.
5. After clicking OK above, the MCU selection window will come up. Fill as shown in the image below, selecting the STM8s103F3P microcontroller.
You can quickly search for the microcontroller by typing its name in the search bar. With this done, click OK. You should now be able to see the STVD workspace.
6. Next, we need to add the SPL libraries we downloaded to the project files. To do this, expand the project folder (newproj) in the workspace, right-click on the “Source files” folder and click on the “add files to folder” option and navigate to the “src” folder in the library we downloaded. select all the “.c” files in the folder and add them.
7. Next, we need to also add the header files. Right-click on the “include files” folder on the workspace, and select “Add files to folder“. Navigate to the “inc” folder of the library we downloaded and add all the “.h” files.
8. Verify library addition and general setup by building. Click on the “build” button and select “rebuild all” followed by the “compile” button.
If the build is successful, you should see “zero build errors” displayed on the command line like in the image below.
With this done you are now ready to start writing the code for our project.
As mentioned earlier, the code for today’s project will be to blink the onboard LED at certain intervals. As with all our projects, I will do a brief explanation of the code and provide the complete code at the end.
The code will be written in the main.c file which is automatically generated when you create a new project. We start the code by including the STM8s library, which helps adds some level of code IntelliSense to our project.
#include "STM8S.h"
Next, we write the delay function. Unlike with the Arduino where the functions are pre-written and we just call them to use, here you have to write most of the functions your self. The delay function will be used to indicate how long the led stays in a particular state before switching to the other state.
void delay (int ms) //create delay function
{
int i =0 ;
int j=0;
for (i=0; i<=ms; i++)
{
for (j=0; j<120; j++) // Nop = Fosc/4
_asm("nop"); //Perform no operation //assembly code <span style="white-space:pre"> </span>
}
}
Next, we write the main function. We start by deinitializing Port B, i.e., the port to which the pin of the onboard led is associated. While deinitializing the port is not mandatory, it helps totally free up the port from whatever function it was used for before, ensuring your project is hitch-free.
main()
{
GPIO_DeInit(GPIOB); // deinitialize port B
Next, we declare the pin to which the onboard led is connected as a push-pull output pin with default low status.
Finally, we write the while loop function. Here we basically place the code to turn ON and OFF the onboard led. For this, we will use the GPIO_WriteReverse() function which reverses the state of the pin. So if it was on before, it turns it OFF, and vice versa. We will also add a delay of 200ms to allow us to see the blink without the eye’s persistence effect.
while (1)
{
GPIO_WriteReverse(GPIOB,GPIO_PIN_5);
delay (200);
}
}
The complete code for the project is provided below;
/* MAIN.C file
*
* Copyright (c) 2002-2005 STMicroelectronics
*/
#include "STM8S.h"
void delay (int ms) //create delay function
{
int i =0 ;
int j=0;
for (i=0; i<=ms; i++)
{
for (j=0; j<120; j++) // Nop = Fosc/4
_asm("nop"); // just an assembly code.
}
}
main()
{
GPIO_DeInit(GPIOB); // deinitialize port B
GPIO_Init (GPIOB, GPIO_PIN_5, GPIO_MODE_OUT_PP_LOW_SLOW);
//Declare PB5 as a default low push-pull output pin
while (1);
{
GPIO_WriteReverse(GPIOB,GPIO_PIN_5);
delay (100);
}
}
Uploading the Code
With the code complete, its time to hook up your board to your computer and upload the code. The process of uploading code to the board is not as straight forward as with the Arduino IDE but its easy to follow and should become seamless once you get the hang of it.
Once the code is complete, click on the Build -> rebuild all and ensure there are no errors. If everything is fine, it should return the “0 errors and o warnings” line. With this done, hit the Compile button. If there are no errors, the program should compile easily and you should see the “0 errors and 0 warnings” in compile success line.
With the successful compiling, a “.s19” file will be generated under the debug directory of the project’s folder. This file is similar to the Hex file and it’s what you will upload to the microcontroller. To upload the .s19 file to the microcontroller we will use the ST Visual Programmer (STVP) which would have been installed alongside STVD.
When opened, the STVP presents the configuration page shown below. Select the programmer, the programming mode, and the device/microcontroller which in this case are ST-Link, SWIM, and STM8s103F3 respectively.
Hit the OK button when complete. This should launch the STVP interface.
Click on “file->Open” and navigate to the debug folder where you have the .s19 file we generated earlier and open it. Click on “Program”and select “Current Tab“. These should begin the flashing process and the firmware should now be loaded on your microcontroller. If successful, you should see the following line on the command prompt area of the software:
and the LED on the STM8sblue should also start blinking at a pace equal to the 200ms we specified.
It is probably important to note that before launching the STVP, you should connect the microcontroller via the ST-link to your computer. If you are using the ST-Link for the first time, the device driver will automatically be installed on your PC. If this is not the case you might need to run a quick google search to find out the requirements for your computer.
That’s it, folks! There you have it. If you have any challenges with any part of the project, do reach out to me via the comment section. I will be happy to help.
This project is a clock with radio receivers that can receive the exact time from the GPS satellites or from the DCF77 transmitter. by hkdcsf @ hackaday.io
This project is a clock with radio receivers which can receive the exact date and time from the DCF77 time signal transmitter or the UTC from the GPS satellites and display it on a 128×64 pixel graphic display. DCF77 transmitter and GPS is synchronized to an atomic clock. So basically this project can “connect to” an atomic clock.

Pervasive Displays (PDi) has announced a new wide operating temperature range for its Spectra e-paper displays (EPDs). The Spectra range comprises 12 EPD modules with size options from 1.54 to 12.2”.
These small, low power, active-matrix EPDs can now operate from zero to +40°C (10°C lower than before) making them suitable for most indoor and many outdoor operating conditions.
EPDs are bistable, meaning that they require no power to display an image and use very little power to update the screen. The one time programmable (OTP) feature of each EPD module operates alongside the internal timing controller (iTC) to store an image waveform inside the display driver. As there is no requirement for the host processor to load an image at startup, the time to the first image is reduced, improving the user experience.
Alchin Wang, General Manager, Pervasive Displays, said:
“We’ve increased the lower end of the operating range of our Spectra EPDs down to zero from 10°C. As the uppermost temperature they are capable of operating in is +40°C, these low power screens are now a great option for a variety of applications where reliability is paramount such as in cold chain, healthcare and warehouse setting.
“And, as these EPDs all benefit from iTCs, we can offer customers a product which is smaller and lighter, saving them space on the PCB and reducing the bill of materials.”
