Temperature Sensing Tutorial With ESP32-C3-DevKITM-1 Using ESP-IDF

Posted on 28 July, 202128 July, 2021 by Saumitra Jagdale

Espressif’s ESP32-C3-DevKitM-1 is extremely popular due to its many onboard features. The development board comes with an onboard Temperature Sensor, an Onboard RGB LED, ESP32-C3FN4 4 MB embedded flash memory, 384 KB ROM, 400 KB of SRAM, universal connectivity with Wi-Fi and Bluetooth and many more.

The ESP32-C3-DevKITM-1 features an onboard Temperature sensor. A temperature sensor basically generates a voltage that varies with temperature. Hence, the voltage is internally converted via an ADC into a digital value which is then scaled to standard units and displayed. This onboard temperature sensor has a range of –40 °C to 125 °C. Also, it is primarily for sensing the temperature change inside the chip.

In this article, we focus on programming of ESP32-C3 with ESP-IDF. You can go through the getting started article of ESP32-C3-DevKITM-1 if you are new to ESP-IDF environment. We use the in-built example provided with the ESP-IDF environment to program the sensor.

ESP-IDF or Espressif IOT Development Framework is the native software development framework for the ESP-32. It essentially contains all API (software libraries and source code) for ESP32 and required scripts to operate the Toolchain. ESP-IDF follows a Command Line Interface (CLI) approach to writing a program. You can learn more about ESP-IDF on Espressif’s official website.

Components for Temperature Sensing on ESP32-C3-DevKITM-1:

ESP32-C3-DevKitM-1
USB 2.0 cable (Standard-A to Micro-B)
Windows PC
ESP-IDF Software (master version)

The following is the procedure to build and flash the program for the ESP32C3 onboard temperature sensor to obtain and display the current out the temperature on IDF Monitor.

First, make sure that you have the latest version of the ESP-IDF with the latest API, libraries and toolchains installed on your computer.

Step1: Launch your ESP-IDF CMD Environment.

Step2: By default, you will be in the esp-idf home directory, change the directory by using the cd.. command.

Step3: Make a copy of the temp_sensor folder situated in the examples folder of esp-idf home directory in the current location using

xcopy /e /i %IDF_PATH%\examples\peripherals\temp_sensor tsensor command.

Step4: Switch to the newly created folder using cd tsensor command.

Step5: Build the program compatible with the board you have using idf.py set-target and idf.py menuconfig commands and then execute the idf.py build command.

Step6: Connect the board and flash the program using idf.py -p (PORT) flash. Enter the Port connection of your board. You can find this using the device manager on your PC.

A Done message will appear indicating completion of flashing operation. The Idf.py monitor command gives the real-time status of temperature from the board.

The following is the output result from the sensor on the IDF Monitor.

The temperature value depends on factors like microcontroller clock frequency or I/O load. Generally, the chip’s internal temperature is higher than the ambient temperature. You can also use this temperature sensor to monitor your ESP32 C3 board or as a supplementary data input to your project’s main code. For exploring more about the development, you can also program the development board on Arduino IDE as well. Check out this article for getting started with ESP32-C3-DevKITM-1 on Arduino IDE.

MYA15XC-T CPU module: MYIR’s second tiny ARM SoM

Posted on 28 July, 2021 by Abhishek Jadhav

We have seen many system on modules in the market already targeting consumer electronics and smart homes. For newbies, a system on module is an embedded computer that can be plugged in or soldered with the carrier board. China-based MYIR has launched the MYC-YA15XC-T CPU module that is the second tiny Arm system on module built around the STM32MP1 series processor.

Since this is the second module in the Arm-based system on modules manufactured by MYIR, this MYC-YA15XC-T has a smaller footprint, measuring only 39mm by 37mm. The MYC-Y157XC-T module comes with the STM32MP151AAC3T processor and STMicroelectronics’ STPMIC1 power management IC. However, it is important to note that the system on module is also compatible with STM32MP153AAC3 and STM32MP157AAC3 processors and can be customised.

When compared to its predecessor, it features no Ethernet PHY chip on board. This module is manufactured with different configurations varying in storage and memory. The module ranges from 256MB DDR3 and 256MB NAND flash up to 512MB DDR3L and 4GB eMMC flash storage.

The MYC-YA15XC-T CPU module is delivered with a shielding cover by default. A number of peripherals and IO signals are brought out through a 1.0 mm pitch 148-pin stamp-hole (Castellated-Hole) expansion interface to make the module an excellent embedded controller for applications like industrial control, consumer electronics, smart home, medical and etc.

Regarding the software support for the hardware, it is capable of running Linux OS and comes with detailed documentation for hardware and software setup. When we talk about a system on module, it often requires a carrier board. But what if the same setup is provided on a PCB making it a powerful development board with a rich set of interfaces. The MYD-YA15XC-T development board supports Linux OS and features 1x USB Type-C DRP, 2x USB2.0 host, a gigabit ethernet, LCD, camera, and Micro SD card slot.

According to LinuxGizmos, the MYD-YA15XC-T module is expected to be priced from $20 to $31. For more information on the module, visit the product page, and the specifications on the development board are also provided.

Meet LUNA; A Multi-tool for Building, Hacking and Analyzing USB Devices

Posted on 28 July, 2021 by Emmanuel Odunlade

Despite its popularity, the developments of USB-based devices are characterized by diverse challenges ranging from specialized and expensive tools to complicated software. To solve this, Colorado-based open-source hardware manufacture; Great Scott Gadgets, recently started working on LUNA; a multi-purpose tool for USB devices development.

Designed as a “swiss army knife” solution for all things USB devices, LUNA is a multi-tool for building, monitoring, hacking, and analyzing USB devices. It features a unique, FPGA-based, digital hardware architecture, which, combined with the remarkable nMigen gateware-generation library along with several supported ultra-fast open FPGA tools, puts in the hand of users, a device that can automatically customize itself to suit the task hand.

On the Hardware level, LUNA features the Lattice Semiconductor LFE5U-12F ECP5 FPGA with the Microchip SAMD11 debug controller which provides access for configuration of the FPGA along with a number of interfaces for diagnosis. For connection of USB devices, LUNA features 3 High-Speed USB ports(2 Type-C and 1 Type-A), each connected to a USB3343 PHY with up to 480Mbps speed, and defined for specific communication mode/usage. An onboard 64MB RAM aids buffering of USB traffic while a 32MBit SPI-connected flash is available for PC-less FPGA configurations. These hardware features and functionalities put LUNA on a close enough pedestal as some expensive commercial USB analyzers like the TotalPhase Beagle 480.

On the software Side, LUNA uses the open-source ViewSB analyzer frontend with a FaceDancer Backend. ViewSB makes USB traffic more human-readable at any abstraction level, while FaceDancer makes it quick and easy to create or tamper with real USB devices even if you don’t have experience with digital-hardware design, using just a few lines of Python. The combination of these two, along with their open-source nature, makes LUNA one of the most versatile USB hacking and development tools.

Beyond its use by experienced developers to craft new solutions, LUNA also prides itself as an education platform for those looking to learn about developing USB devices. The team at LUNA has a long history of USB education and the resources from the several open-source training and workshops developed in the past, along with more LUNA-specific, fully open-source materials, are available to walk beginners through the basics of working and hacking with USB.

The customizable architecture of LUNA, allows users to interact with USB traffic at every level. which facilitates hacking but also enables learning, as it gives you the ability to take the data apart, split it up and evaluate it in ways that are not available in other solutions. This makes LUNA a goto tool for both veteran low-level hardware designers and complete newbies.

Great Scott Gadgets recently launched a crowdfunding campaign for LUNA on Crowd Supply with a funding goal of ÚSD80,000 with prices set at $99 for the LUNA board without enclosure, and $149 for the full-featured LUNA. As of the time of this writing, the campaign has been oversubscribed by almost 50%, with over $149,000 raised just 5 days after the campaign was launched. The campaign is expected to run for the next 30 days after which manufacturing, which according to the LUNA team will be done in China, is expected to kick into top gear.

LUNA is entirely open source with its hardware, gateware, firmware, and software files, all available on the team’s GitHub page, along with developer documentation on ReadTheDocs that shows how to get up and running with the LUNA Board.

More information on LUNA can be found on the project’s page on CrowdSupply. You can also interact with the LUNA team, and ask questions about the product via the LUNA Discord Channel, the LUNA IRC Channel, or the company’s Twitter page.

Open Source DC-SCM Compatible BMC Hardware Platform

Posted on 28 July, 202128 July, 2021 by Tope Oluyemi

The popularity of Open source software has brought about impressive successes in the SaaS space, where useful products can be rapidly created from open source components. We see cloud providers and users looking at building their servers using open source hardware as well. This is where Antmicro steps in. Antmicro has been supporting companies like Google, in creating useful server-facing open source hardware such as Scalenode or ARVSOM. One of these projects with Google is an open source hardware FPGA-based Baseboard Management Controller (BMC) platform compliant with the new DC-SCM specification to help increase the security, configurability and flexibility of server management and monitoring infrastructure, which has been adopted by the LibreBMC workgroup as the base hardware platform.

Developed by the Open Compute Project, the Datacenter-ready Secure Control Module (DC-SCM) is designed to move common server management, security and control features from a typical motherboard into a module designed in one of the two form factors featured in the specification (Horizontal or Vertical), which can be used across various datacenter platforms. This spec will enable leading players in the industry share costs, risks and increase reuse. Speaking about the benefit of the DC-SCM, the company says:

“Coupled with a fully open source implementation based on our open source FPGA-based modules, it has a chance to redefine the way board management is done. Basing the module on popular, inexpensive FPGA platforms will not only allow for more configurability and a tighter integration between hardware and software, but also tap into the momentum behind the broader open source hardware community via groups like CHIPS Alliance, OpenPOWER and RISC-V.”

The company developed two implementations of the DC-SCM-compatible BMC, with both designs meeting the Open Compute Project specification for a Horizontal Form Factor 90×120 mm DC-SCM. The BMC is designed to monitor the system, prevent and mitigate failures, and act as an external watchdog. The module enables a feature-packed Secure Control Interface for communication with the host platform, including:

PCI Express
USB
QSPI
SGPIO
NCSI
multiple I2C, I3C and UART channels.

What is unique about the BMC is merging DC-SCM’s central Baseband Management Controller and programmable SCM CPLD block into one powerful FPGA. This solution enables remote updates of DC-SCM peripherals, and most notably, placing OpenPOWER or RISC-V IP cores as central processing units of the module. One of the designs is based on the Xilinx Artix-7 FPGA, and the other one features a Lattice ECP5 FPGA, which are both low-cost and open source friendly FPGAs supported by the open source SymbiFlow FPGA toolchain project which the company is involved with. The FPGA features 512MB of DDR3 memory, 16GB of eMMC flash, and also a dedicated Gigabit-Ethernet interface. For security of the Datacenter Control Module, external cryptographic modules: Root of Trust (RoT) and Trusted Platform Module (TPM) can be connected.

The DC-SCM boards which is being adopted by the LibreBMC Workgroup, operates under the umbrella of the OpenPOWER Foundation. The LibreBMC workgroup, in conjunction with IBM, Google and Antmicro, among others, are involved in creating FPGA gateware and software needed to make the hardware fully operational in real-world server solutions. About future plans for the BMC, the company says:

“Variants involving both Linux (in its default open source server-oriented distribution, OpenBMC) and Zephyr RTOS, as well as with both POWER and RISC-V cores are planned and thanks to the flexibility of FPGA all of those options will be just one gateware update away. Of course, both the gateware and software will be open source as well.”
