Re: Help with Pololu DRV8711 Stepper Motor Driver

looks like it wants MSB first..... mode 1 on shiftout ???

Re: Help with Pololu DRV8711 Stepper Motor Driver

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...

Re: Help with Pololu DRV8711 Stepper Motor Driver

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?

Re: 64 pin 18F series MCU, which operates from 5V and has same pinout as 16F series?

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!

Re: Help with Pololu DRV8711 Stepper Motor Driver

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...

Re: Help with Pololu DRV8711 Stepper Motor Driver

THANKS! Good catch and yes, I feel stupid. I will give this a try and let you know if that was it! Jeff

Re: Help with Pololu DRV8711 Stepper Motor Driver

Looks like you're shifting out $1180 divided by 16, truncated to 8 bits, so $22. That's not what you want, is it?

Be careful with / vs \ ;-)

Re: 64 pin 18F series MCU, which operates from 5V and has same pinout as 16F series?

Likely no direct drop-in with those exact specs. Consider lower speed, external clock, or other PIC families (needs PCB change).

Help with Pololu DRV8711 Stepper Motor Driver

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...

64 pin 18F series MCU, which operates from 5V and has same pinout as 16F series?

Hello.
I really do not know in which part of forum to ask, so move this topic according to your decision.

I have the following issue. I have PCB designed for 16F1947 chip, in 64 pin package....
