Heya Arduino Fans!
I recently wanted to swap from DRV8825 to the TMC2209 stepper motor drivers.
I just got them delivered: (系统发生错误).
They work perfectly fine as replacement together with my ArdunioUno and Nano.
I was just wondering about the so called "Diagnostic" Pin, which suggests to be readable (and I think its used for the sensorless homing feature - StallGuard afaik).
To get this into context, and to finally deliver a real question:
My project currently just uses one motor in continuus rotation at set speed (using the AccelStepper lib.). However, I would like to use a read out from the stepper driver if the motor starts skipping steps (due to high rotational speeds) or if the required torque for the rotations exceeds a specific limit. Is this possible without using a motorshield? I couldn't find any (for me) understandable explanations on the web.
Help is highly appreciated!
