LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

@viewsat do you have some more informations about the DrDirt - Carrot Bob board ?
documentation, pinouts schema's or so, or a contract mail to the seller/developer,

I’d like to add it to Rio-Flow and still need a bit more information to do so.

I have a json file that I can provide; other files may not be publicly available for download here.
 

Dear meister：

The CARROT BOB sch is in attachments.

I build it for my hobby mini mill machine in my bedroom.
I think it's not very good just like my English,and I don't know how to send it to you,you are live so far with me.
I'm so happy you like it , if you know the way, I'll send it to you for free

Thank you Tim,

Thanks very much for the details; I’ve entered the board’s details as best I could,
I hope it’s all correct so far – please do have a look over it.
What’s not quite clear to me yet is, how do you flash it? Are there any connectors on the back?

You’re also welcome to send me some text and a link for the description, and I’ll update it.



 

Dear meister:

It's looks so cool!

In attachments is user manual in English version that I translated help with AI.and pcb top/bottom views

Yes, On the bottom of PCB have some testpoint to download firmware

Hi!I ran into a weird issue with my Tang Nano 9K setup (using Axis).On startup, LinuxCNC doesn't seem to read any inputs from the FPGA until I manually toggle E-Stop off in the UI (F1) at least once. After that initial click on screen, all physical buttons and inputs work perfectly.It's a bit of a chicken-and-egg problem, as I can't use a physical reset button to clear the initial E-Stop on launch.Is the communication loop paused while in initial E-Stop, or is there a way in HAL to make RioCore poll and update inputs right from the start?Thanks!
