I am using a pololu DRV8825 driven by a DSPIC32 microcontroller.
I added a 0.01R resitance in series from the Vmot pin and an INA180 for the amplifier to measure the current of the stepper.
I compared the current when the stepper is working properly and when the stepper is stuck.
But when it is blocked, it has no more current, and the waveform of the current is almost the same as in normal operation.
Who has a solution to detect the stepper blocked by the current?
