As I had received a handful STM32 MCUs, I managed to solder one on the “blue pill” board from which I had desoldered a fake/defective one. The new MCU seems to be working fine, having tested the DC2N5-LC firmware with … Continue reading

Quite a satisfying result for the day

I finally got the time to desolder the MCU from one of the STM32F103C8T6 boards I recently received. Here’s what the board looks like after the operation: The MCU will soon be on its way to Finland for de-capping, which … Continue reading

STM32F103C8T6 Minimum System Development Board Module – More Shenanigans

For years I used to buy the so called “STM32F103C8T6 Minimum System Development Board Module” on eBay and had no issues with it. However, I recently made an order and I am frustrated to say that it seems Chinese manufacturers … Continue reading

SysTick with STM32CubeMX

OK, so it appears that with projects generated through STM32CubeMX the place where to insert custom SysTick code is not within the HAL, but in one of the auto-generated “User” files, stm32f1xx_it.c. This file contains the definition of active IRQ … Continue reading
