Where define/where to find defined IO-pins?

[Elmi77]

Hi,

following the "compiling"-documentation I have set up my environment fir usage with an STM32F446, with 4 axes and no further interfaces/functions than UART for communication - but with a generic board as I plan to have my own hardware. Now my question is: which ports and pins are used for axis/direction/limits? Which UART is used? Or to be more accurate: where is all this stuff defined?

Thanks!

In a board map, when for a custom one-off board add my_machine_map.h to boards and if you want copy the contents of one of the existing ones to it as a start. Enable it in my_machine.h.
