Since the GD32F103 can run as fast as 108MHz but has not a proper USB clock divider to provide a 48MHz clock for USB communication we need another way to communicate with the outside world. Since the early days of computing the easiest way to go is a asynchronous...

The defacto ‘hello world’ for microcontrollers is blink a LED at a steady rate. This is exactly what I’m going to do today. I made a small 5×5 development board, soldered it up and started programming. In this first example we not gonna use...

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...

A couple of times a year I send in a bunch of PCBs. As usual I combine multiple designs and have them delivered express. That sounds a bit expensive but when ordering about 4-5 designs the cost is almost the same as the other snailmail options. I also make sure I send...

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...
