THANKS! Good catch and yes, I feel stupid. I will give this a try and let you know if that was it! Jeff
Atom058 Yesterday, 20:52Looks 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 \ ;-)
Likely no direct drop-in with those exact specs. Consider lower speed, external clock, or other PIC families (needs PCB change).
WonderNom Yesterday, 10:35Hello - 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...
Atom058 - 12th May 2025, 22:04Hello.
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....
I played with the MCP25625 (CAN controler and driver) using the SPI peripheral on the 18F57Q53 a while back (just looked, turns out it's 4 years ago now, bloody hell...).
My intention was to make a...
Very useful info that are posted in this thread, but I am afraid that CAN topic is not very popular!
Thanks anyway for your kindness to share your experience.

Anyone got anything else to add/share please??
I bared my feeble CAN soul, now it's your turn.
Watch out for the slew rate control bit in PICS.
It defaults to on in the PIC18F26K80!
This screwed me for hours as the SPI just kept falling over above 1mhz.
Not enough drive power for the...
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.
