ATtiny Flasher: An open-hardware flashing tool for the Atmel ATtiny

Posted on 11 May, 202111 May, 2021 by DM

Arduino development boards are highly popular among makers and beginners in electronics for their ease of use. The Arduino boards are designed in such a way that making connections to peripherals like sensors and displays is extremely easy. All it needs is a little common sense for interfacing components and you are good to go with your project. A part of this convenience in using Arduino boards comes from the Arduino IDE (Integrated Development Environment). Arduino IDE is an open-source platform that makes writing code and uploading it to an Arduino board easy. Arduino IDE uses C/C++ for programming but the environment also has helper functions that enable you to use the hardware easily. Along with this, it also has a serial monitor and plotter which can plot analog values of a variable in real-time. All of this makes Arduino boards very convenient for prototyping.

But, the form factor of various Arduino boards is a major issue when designing compact projects. Even the Arduino Nano, the smallest Arduino development board, though small and breadboard friendly, can’t be used in compact circuit boards. Sometimes you may not even need more than 2-3 I/O pins for your project so, using Arduino for the same is overkill. In addition, Arduino boards are expensive as compared to their chip price. Thus, if you want a cheaper, simpler, and more compact alternative to Arduino boards, ATtiny microcontrollers are perfect for your needs. ATtiny microcontrollers are AVR microcontrollers based on RISC architecture developed by Microchip technology. ATtiny85, ATtiny45, ATtiny25, and ATtiny13 are very popular compact microcontrollers of the ATtiny family.

If we want to program an ATtiny chip via Arduino IDE, we need to use one of the Arduino development boards as ISP and then burn the program on the chip. There are many challenges involved in burning the program to ATtiny. One of the issues that arise is wiring problem and reset capacitance which obstructs the programming to the chip. The ATtiny Flasher is the right device made for this purpose.

It is a handy device that allows you to use your favorite IDEs and debugging tools when developing for the ATtiny microcontroller. This device allows you to upload your code from Arduino IDE or any other without having to port your code to its intended program. It is built around Arduino Nano which provides compatibility with most IDEs along with an OLED for the display of the status of the upload.

Features and Specifications of the ATtiny Flasher:

Allows you to flash ATtiny85, ATtiny45, ATtiny25, and ATtiny13 via breadboard or onboard header.
Flash the entire ATmega family via onboard ISP header
Flash using Arduino IDE, Platformio, or any other IDE of your choice
Two configurable power rails, either 3.3 V or 5 V
Six GPIO “weak” LEDs
Three flash-status LEDs
Onboard OLED screen connected to target MCU as a live terminal
Streams serial data to the host PC as if it were connected directly to the target MCU. (Yes, serial on ATtiny. Even ATtiny13!)
A buffer IC between target and host MCUs only connects the two while flashing
Open hardware is driven by open-source software

Vishay’s New Proximity Sensor Offers Power Consumption Down to 6.63 µA

Posted on 10 May, 2021 by mixos

Featuring a VCSEL and Small 1.6 mm Light Hole, Device is Ideal for Consumer and Industrial Applications, Including TWS Earphones and VR / AR Headsets

The Optoelectronics Group of Vishay Intertechnology, Inc. today introduced a new fully integrated proximity sensor designed to increase efficiency and performance in consumer and industrial applications. Featuring a vertical-cavity surface-emitting laser (VCSEL), the Vishay Semiconductors VCNL36825T combines a photodiode, signal processing IC, and 12-bit ADC in a compact 2.0 mm by 1.25 mm by 0.5 mm surface-mount package with a small 1.6 mm light hole.

As compared to previous-generation devices, the newly released proximity sensor offers a 76 % smaller package, while its reduced light hole opening provides increased design flexibility — all at a lower cost. The VCNL36825T’s small size makes it ideal for space-constrained battery-powered applications, such as detecting if users are wearing or not wearing true wireless stereo (TWS) earphones or virtual reality / augmented reality (VR / AR) headsets. With a range of 200 mm, it also provides collision detection in toys and consumer and industrial robots. The proximity sensor features low power consumption down to 6.63 µA to increase efficiency in these applications.

Specifications

Part number: VCNL36825T
Function: PS + VCSEL
Package size (mm): 2.0 x 1.25 x 0.5
Supply voltage (V): 2.64 to 3.6
I²C bus voltage (V): 1.7 to 3.6
VCSEL Driving current (mA): 20
Operating range (mm): 200
Min. Power consumption (µA): 6.63
Proximity resolution: 12 bits

The VCNL36825T supports the I²C bus communication interface for easy access to the proximity signal, while its programmable interrupt function allows designers to specify high and low thresholds to reduce the continuous communication with the microcontroller. The proximity sensor uses intelligent cancellation to eliminate cross-talk, while a smart persistence scheme ensures accurate sensing and faster response time. The VCSEL wavelength peaks at 940 nm and has no visible “red-tail.”

The device offers excellent temperature compensation from -40 °C to +85 °C, and a Moisture Sensitivity Level (MSL) of 3 — in accordance with J-STD-020 — for a floor life of 168 hours. The sensor is RoHS-compliant, halogen-free, and Vishay Green.

Samples and production quantities of the VCNL36825T are available now, with lead times of eight to 12 weeks for large orders.

How to multiplex a 1-Wire master into numerous channels

Posted on 10 May, 2021 by mixos

This is an app note from Maxim Integrated on using only one 1-wire master on multiple 1-wire channels.

1-Wire® networks are originally designed for communication with a single 1-Wire master and numerous 1-Wire slaves on a single 1-Wire bus. Preferably, a linear topology, which contains insignificant stubs, is best for a 1-Wire network. However, a star topology, which contains long stubs, is often unavoidable, and makes it more difficult to determine the effective limitations. A method to eliminate these difficulties is to break up a star topology into numerous channels by using an analog multiplexer (mux). Advantages of using numerous channels include accelerating individual 1-Wire slave access time, improving network robustness, and mixing overdrive-only slaves with standard/overdrive slaves on different channels. These advantages can be gained while still having a single 1-Wire master.

Würth Elektronik presents its Bluetooth module Proteus-III-SPI

Posted on 10 May, 2021 by mixos

Würth Elektronik introduces the Proteus-III-SPI Bluetooth Low Energy 5.1 module. This variant of the tried and tested Proteus-III uses an SPI instead of a UART interface. The new module, based on the Nordic Semiconductor nRF52840 chipset, exploits the possibilities of the Bluetooth Low Energy 5.1 standard—with significantly higher performance. With a payload of up to 964 bytes, the module offers four times the throughput of most Bluetooth low-energy modules. As the SPI allows a significantly higher data rate than the UART, with 1.5 times the end-to-end data throughput, the SPI variant bypasses potential bottlenecks on the application side.

The Proteus-III-SPI variant—identical in terms of hardware—is the first choice for applications in which no free UART interface is available, or if the data throughput of the UART interface is insufficient. Another advantage: The SPI variant is more power efficient. The integration workload is slightly higher with SPI, but Würth Elektronik provides a convenient wireless connectivity software development kit (SDK) for this task.

With its Bluetooth module, measuring just 8 x 12 x 2 mm, with integrated antenna, encryption technology and six configurable IO pins, Würth Elektronik offers an interesting solution for IoT and M2M applications in radio-based maintenance interfaces and sensor networks. A special feature of the innovative Würth Elektronik solution: Proteus-III-SPI offers a good alternative to the SPP (Serial Port Profile) mode for serial data transmission, which is no longer included in the standard, but is extremely useful for industrial applications. A long-range mode is included. Proteus-III-SPI is now available ex-stock without a minimum order quantity.
