Hello,
Have a weird problem and I can not find the cause.
We use a drv8824 with pin 19 (decay) loose so it's in mix mode.
It's already happened a few times that the decay input is faulty.
The driver is going in slow decay and the input gate 19 (decay) no longer responds to a signal (low-high or loose). The stepper motor makes noise and does not run properly.
This has happened a few times, the driver chip is defect but only the decay input pin.
Does anyone have an explanation for this?
Hope someone on this forum knows a solution to this!
Thanks.
