W5100S-EVB-PICO stepgenerator and encoder driver

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

moving

Update
1.variable pulse width for the step generator (1000nS - 6000nS) set from hal pin.
2.work with pico + w5500 module (connections like in the w5100s-evb-pico)
 

You say the PI pico connection (connections like in the w5100s-evb-pico), but the Pico pins are different for the SPI0, or am I wrong?
I have another question: if I'm going to use your io-samurai, would I need another network card?
 

 
if you use normal pico and a w5500 board, you need to wire like the dark blue pins in the w5100s-evb-pico, pinout here w5100s-evb-pico pinout new video here Embeddedtronics testing stepper ninja

you need a network switch to connect
