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

hate modbus protocol

sorry, need some time to fix that problem

EDIT2:
I have now ordered a 32 relay card,
I will not receive the 16-channel card in time.

The protocol is a bit different, but it looks like I'll have to write a sub-plugin for each type, as no one really follows the standard

ok, until I have a better solution,
I have added a new 'type' (201 : Custom Boolean)

sample config (gui setup will not work / need to added by hand in the json config):
"on": the bytes of the frame to switch the output on (without address and checksum)
"off": the bytes of the frame to switch the output off (without address and checksum)

Hi Olli
Thank you very much for your efforts, I will download the latest dev of riocore tonight and will let you know how it goes.

i got my 32 relay card today and changed something in the setup, i will test everything again later.

you can now use func:6 and set the datatype (new option) to bool, as register the 112 (0x70) and Values = 16

 

Works for me

the modbus has some delay, thats why it is a little asynchronous


@Andrew
there is also a template now for your board, but without input yet, would be nice if you can give me your config for the inputs

Hi Olli
Thank you once again for your prompt response to my issue.
I have done a very quick test and at the moment I am over the moon, all the outputs work as they should.
I am using your template for N4D3E16, with exactly your settings.
When I use LinuxCNC it works perfectly, but if I use the test-gui in riocore the outputs work, but i get the following errors in the terminal window.

I will test for a little while longer to see if I can figure out if I have configured something incorrectly.

To use the inputs originally I used the following settings. I cant remember why I broke them into lots of 4, I'm thinking that if I put a "values" as 16 it wouldn't work

"inputs1_4": {
"address": 1,
"type": 3,
"register": 129,
"values": 4,
"is_float": false,
"scale": 1.0,
"unit": "",
"error_values": "",
"format": "d",
"timeout": 100,
"delay": 60,
"direction": "input"
},
"inputs5_8": {
"address": 1,
"type": 3,
"register": 133,
"values": 4,
"is_float": false,
"scale": 1.0,
"unit": "",
"error_values": "",
"format": "d",
"timeout": 100,
"delay": 60,
"direction": "input"
},
"inputs9_12": {
"address": 1,
"type": 3,
"register": 137,
"values": 4,
"is_float": false,
"scale": 1.0,
"unit": "",
"error_values": "",
"format": "d",
"timeout": 100,
"delay": 60,
"direction": "input"
},
"inputs13_16": {
"address": 1,
"type": 3,
"register": 140,
"values": 4,
"is_float": false,
"scale": 1.0,
"unit": "",
"error_values": "",
"format": "d",
"timeout": 100,
"delay": 60,
"direction": "input"
}
},


Thanks again.
