Product Number: TMC2209
Hi I am working on creating a custom stepper driver PCB with TMC2209 ( a 4 layered PCB ) and I see that the B1 and B2 are outputting same phase outputs whereas there is expected to have a 180* phase difference between both the PWM outputs.
I tested there is no physical shorting of B1 and B2 pins (as seen on Multimeter continuity mode) and the trace width is 0.4mm and a gap of 0.2mm.
I am considering increasing space for the next revision but is that actually the issue or am I missing some software/register setting that may cause this.
I can surely see jittery movement of the motor, but same code is running with TMC2209 Step-stick board.
This is expected waveform (5V VM):
This is what I am getting:
