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...

The battle isn’t AVR Atmega vs Microchip PIC anymore.. More and more people are moving to ARM chips. As easy as it sounds but it isn’t. ARM is an company that invented the ARM chips, but doesn’t has a silicon fab, instead they license the design to...
