Remora - Rpi Software Stepping Using External Microcontroller via SPI

Hi,

This is not something that can be configured with the QEI driver. You would need to compile your own version.

In qeiDriver.cpp you would need to change the encoder mode configuration.

Line 55: Change to TIM_ENCODERMODE_TI1 or TIM_ENCODERMODE_TI2 to count only on one input.

See section 17.3.16 in the SMT32F4 manual.

Maybe this dumb question, can we operate this with usb in bluepill?
I want to move from old bob with this... I still have an old pc with out db25 port..

Yes to bluepill, no to usb. You need to use a raspberry pi SPI

How about use w5500 to conect with spi??

In the future it is possible, but I have not been able to get it working yet with other boards

Great project @cakeslob
