Diag Pin? #83

Open mochoandre opened 8 months ago

mochoandre commented 8 months ago

Is it possible to expose motor DIAG pin (virtual endstop) so it can be used in new Happy Hare ERCF "touch"function?

DIAG is connected to GPIO29 on SB2209 (RP2040) and PB3 on SB2209 and SB2240 so it should be possible to setup touch/stallguard.

and on EBB36 is it possible?

No that board doesn't seem to have the DIAG pin wired according to the schematics. Since the TMC2209 chip doesn't have exposed pins it's also quite hard to modify the board yourself by soldering a wire. Maybe there is still a pad that the DIAG pin is soldered to that is somewhat exposed, I don't have a board to look at myself.
