rePalm

rePalm project from Dmitry.GR As I mentioned, none of the native API of PalmOS 5.x was ever documented. There was a small number of people who figured out some parts of it, but nobody really got it all, or even close to it. To start with, because large parts are not useful to an app […]

Simple NTP clock using USB display module

Dilshan Jayakody writes: Simple NTP clock is a maintenance-free clock application developed to work on single-board computers like Raspberry Pi, Orange Pi, etc. This clock application uses the Simple Network Time Protocol (SNTP) to get the time and display it on seven segment display which I designed.  This application is designed to work on most of […]

New NXP MCUXpresso Eclipse IDE v11.0

New NXP MCUXpresso Eclipse IDE v11: The V11 of the MCUXpresso IDE is again a big step forward: new Eclipse version and 64bit, updated ARM toolchain, extended debugging support for P&E and Segger in addition to the LinkServer connection. The Global Variables view now supports live variables and graphing for P&E and SEGGER in addition […]

Remote debugging with USB based JTAG/SWD debug probes

Erich Styger wrote an article on how to turn a USB debug probe into a IP-based debug solution: For some projects it is not possible to have the device under debug available on my desk: the board might be in another room, on another site or in a place where physical access is not possible […]

Regaining debug access of NXP i.MX RT1064-EVK executing WFI

Erich Styger writes: Working with low power modes can be challenging. It can severely affect debugging capabilities of a microprocessor or microcontroller. I ported a FreeRTOS application using the Tickless Idle Mode to the NXP i.MX RT1064 board, and all of a sudden, the board was unresponsive to any debugger connection. Luckily the board was […]

The ARM chip that wont cost an arm and a leg

A small ARM developmentboard from SMDprutser, that is available on GitHub: Searching the prerequisite Chinese websites to satisfy my shopping fetish I came across a neat little ARM Cortex-M0 chip which is an extremely good bang for buck. I believe it is the smallest chip available in a reasonable hand-solderable package (TSOP8). This board gives […]

STM32F103 vs GD32F103 round 4: SPI master

Sjaak writes, “This is part 4 in the series where we compare the STM32F103 with its Chinese counterpart the GD32F103. Both are ARM Cortex M3 microcontrollers which are mostly pin, peripheral and register compatible. Now we compare the SPI master peripheral of both chips.” More details at smdprutser.nl. Check out the video after the break. 

LoRa module in DIL form

Mare writes: Murata produces LoRa module CMWX1ZZABZ-xxx based on SX1276 transceiver and STM32L072CZ microcontroller. The soldering of the LGA module is not very hobby-friendly. I constructed small breakout PCB for this module with additional buck/boost switcher and place for SMA connector. The transceiver features the LoRa®long-range modem, providing ultra-long-range spread spectrum communication and high interference […]

STM8 Microcontrollers

Here’s a three-part series of posts by Shawon Shahryiar detailing the STM8 microcontrollers: STM8 microcontrollers are 8-bit general purpose microcontrollers from STMicroelectronics (STM). STM is famous mainly for its line of 32-bit ARM Cortex microcontrollers – the STM32s. STM8 microcontrollers are rarely discussed in that context. However, STM8 MCUs are robust and most importantly they come […]

Programming STM32F103 Blue Pill using USB bootloader and PlatformIO

Coyt Barringer wrote a post on his blog showing how he program the Blue Pill STM32F103 using USB Bootloader and PlatformIO: This is the infamous Blue Pill board – a $2 ARM STM32F103 development board with all the capabilities of a Teensy 3.x at a fraction of the price of an Arduino. So what’s the […]
