Remora - Rpi Software Stepping Using External Microcontroller via SPI

Ok the good news is I can get the firmware down to 116kb, so thats cool

I got the firmware to run on stm bluepill. It only works with the clones that have 128kb memory, so you need to check that beforehand. I dont know if I can get to small enough to add sd card, but it works with the static config. I think I wrote over the usb bootloader though, so i will have to look into it. spi pin out is PA7/6/5/4/3

stm32f103 bluepill remora shield, so far so good

 

Hi
Is there a wiring diagram for a 600 ppr ABZ encoder to be used on a lathe. Sorry if this is a silly question!

I will be using a Nucleo64 STM32F446RE with a cnc shield v3

what is a bluepill remora shield

Will depend on the type of output the encoder has, there should be a blurb in the box...or just throw up the model number and I can advise.

I think Old Mate is referring to the potoo board the MCU board is on.
