W5100S-EVB-PICO stepgenerator and encoder driver

Category: Driver Boards

Dear linuxcnc users,
i want to introduce my new open source project based on the W5100S-EVB-PICO . ~10 USD (raspberry pico clone)

features:
1 to 8 step generator with 255KHz maximum output in this version, (possible higher freq) enough for 15m/min with 0.001mm
1 to 8 quadrature encoder counter with 12.5MHz theoretical maximum counting frequency.

current version in the github page is support 4 stepgen and 4 encoders
linuxcnc driver supports multiple instances
planned direct SPI communication with raspberry-pi4 (with normal pico)

github: stepgen-encoder
