I locked myself into the basement with a couple of PCBs, chips and fresh flux for a couple of days. For the STM32F103 vs GD32F103 challenge I needed to have two identical boards with a different microcontroller. As far as I could judge both chips are legit and not...

Most of us do know the ST line of ARM chips called STM32. They come in multiple flavours and the STM32F103 is one of the most common entry level family of chips. They are called by ST as mainstream. They are a full featured 32 bit ARM Cortex M3 chip running at...

It has been a while since I wrote about ARM development. I recently made a Black Magic Probe (BMP) clone which acts different then the original. The BMP can source power to the target, but on my version control signal is inverted. Not a big deal, but can give...

When you get started on ARM microcontrollers things are very overwhelming at first… After coping with the first few hurdles like installing a toolchain and IDE, the next part should be getting a tool to program the chip. Many vendors have some kind of bootloader...

Since I don’t use the DHL shipping option for PCB, it takes quite a while before the boards roll in. Today came in the STM32/GD32F103 QFN32 breakout board. I was very excited (for weeks) and soldered all the components quickly on the board. Uptill now I used...

Prolly not, but I haven’t made a developmentboard before and I didn’t know of a development board that uses the QFN36 footprint. I recently went on a trip to Shenzhen to visit Ian from Dangerousprototypes.com and there I learned about a big Chinese...
