Amgen - Thanks for your input. Yes, I have tried both Mode 0 and 1 with no luck. I have also tried reversing the SCS pin (low, shiftout, high as opposed to high, shiftout, low) and nothing there...
Yes, I did set ADCON1 and no, I have not used a scope on this yet. Here is the entire code. I am simply trying to initialize the driver and run a stepper back and forth with 2 LEDs that indicate...
Hmm...PortA...have you disabled the analog functions (ADCON1 and CMCON registers, I believe)?
Have you verified (logic analyzer or scope) that the expected data does appears on the pins?
Yes, I already started re-designing the PCB, and discovered that there's an error in datasheet - PIC18F66K80 actually has 52 IO pins, not 54, as stated in the beginning of datasheet!
Well, While that was a problem, it was not THE problem. Still no movement. I tried both mode 1 and mode 0 for the SHIFTOUT methods, also, to no avail.
Here is a snip of the circuit board design...
Hello - I am trying to write a simple program to run a stepper motor back and forth using the Pololu DRV8711 driver (Link: https://www.pololu.com/product/3730). In order to use the driver, you must...
