General Discussion / Testing TMC2100
« on: April 20, 2023, 02:06:09 »
Hello!
I'm testing the TMC2100 drivers with an atmega162 Astroeq.
For some reason the drivers are not responding well to microstepping change. I'm using 2/16.
Measuring the voltage on the CFG pins, when the pin should be GND it is, with 0v. But when is in float, I read 0,3V to 0,4v. Is this enough to trigger a "float" condition in the driver?
Because when I do slew aroung until about 120x the tracking speed, the motor turns very fast, but after that it goes very slowly (like the driver has not triggered a microstepping speed change).
Any Ideas?
Thanks

Any news? Did you make it work?

General Discussion / Astroeq on ESP32
« on: January 17, 2022, 22:41:32 »
How hard would it be to port the code to an ESP32?
It's cheaper and faster than a Mega or Teensy
