On-Chip debugging with STM32 chips

I was looking for a nice IDE integrated on-chip debugging setup for STM32 chips and the STLink V3 on macOS. Neither OpenOCD nor st-util worked out of the box with CLion. I didn’t want to use gdb directly. STCubeIDE works great, but I don’t want to use STCubeMX projects. I’m writing firmware using chibios right now. I wanted something which works for any RTOS without much hastle. So I took some inspiration from how STCubeIDE works. Read more

challenges working on electronics

Working on electronics makes me appreciate how easy software engineering is. Why is that? Personally I can work efficiently when I have a tight feedback loop and when I can simulate the environment I’m working in. This allows me to make small changes and quickly converge my design towards the desired state I want to reach. With electronics establishing a tight feedback loop is much more complicated. Assuming you layed down your schematic, sanity checked all nets and verified your PCB with design rule checks you eventually end up ordering a PCB. Read more
