Re-ARM UART pins for TMC2208 (2 replies)

Hello all,

Am trying to figure out how I can get UART to work on my Re-ARM and get it to control the 4x TMC2208 stepper drivers I need.

Apparently the Re-ARM doesn't break out these pins, so I can't base it on any working configurations (like for the normal 8-bit board)

Don't mind giving up the LCD controller, if I can use any of those pins, since I'm planning to use Octoprint.

Any tips or pointers would be greatly appreciated :)

Thanks!
