Switch on a stair that for every step has a strip led, controlled in PWM. All this to generate a stair "wave effect" for my sister.
under hw there is the hardware under fw there is the firmware
Meh..
I worked on OpenBSD.
For the hardware I used Kicad, for the firmware, vim + Makefile..
The toolchain is arm-none-eabi-gcc-linaro.
The "core" is the STM32 BluePill, some shift registers and some mosfets..
To debug the board I used the st-link with openocd.
$ cd fw/stair/ $ make
$ make debug
