Hi everyone,I've started developing an I/O board using the Raspberry Pi Pico. The prototype will feature 8x 24V outputs and 16x 24V inputs, communicating over Ethernet UDP with a real-time HAL driver. If everything works well, I plan to develop additional boards with step generation, analog outputs, and encoder inputs.At the moment, things are still evolving—I'm currently having the first batch of 5 PCBs manufactured and have already ordered the necessary components. Communication between the Pico and the real-time HAL is already working. :)I'll keep you updated as the project progresses!

Wifi setup is by running

Be sure to edit to choose option 5 "Edit wpa_supplicant" with your country code, ssid & password.

To setup network for a mesa fpga Ethernet card, choose option 6 "Edit interface" and modify eth0 to match post above if you have jumpered the board for "FIXED FROM EEPROM"
If you have jumpered for "FIXED 192.168.1.121" replace 10.10.10.100 with 192.168.1.100.

If your home wifi network is on the 192.168.1 network, use the 10.10.10 network for your Mesa card, refer to you card's manual for jumpers to change.

After config reboot

A final note, there is no network notification applet for the desktop, so you will not get any notifications when the network connects, disconnects or reconnects.

I am new to linuxcnc and I cannot get my Raspberry pi running linuxcnc to connect to wifi or to my mesa 7I92TM board. I tried ip a but the mesa board is not showing have looked everywhere online and read multiple forums but can't seem to find a proper solution to my problem. Please help.

Funny thing is, the Mesa 7c81 and a stacked RPi look like a more compact solution.

NVME would be nice, the RPi5 with a NVME drive is blazingly fast.


Did you stick with the Mesa fpga pin to 7c81 layout ? Or did you change it to make routing easier ?

If you change things around, especially the clock signal, the SPI_CLK for comms is a little tricky to work out to begin with.

Sorry don't mean to add feature creep, man I wish I could design a simple board for the KSZ8851 Ethernet chip for my mesa clone thingy. So hats off to you Old Chap.

I have this one, used on my mill with a PC platform: Expensive
Planar Pct 2235 22" 1920X1080 Full HD Touch Screen VGA HDMI DISPLAY PORT USB

For the RPi5: Cheap

I would assume if the touchscreen interface is USB you should be fine. Tho the raspberry pi forums maybe a better resource, just look\ask for usb hid compatible touchscreen, stipulate USB HID is the only option.
