M-Code Request: Send CAN Message
-
@dc42 Thanks for the quick replies both of you!
I think M42 is not suitable since I would like to send more than a just a Yes/No or PWM signal. The "User Defined" sounds like its exactly what I'm looking for! I hope its not too difficult to implement.

@jml how many parameters do you need to send in a single message?

@dc42 I would think 4 would be enough to cover most things. 5 or 6 would be enough for future flexibility. Maybe 256 just to be safe
just kidding. -
@dc42 Based on your message, it sounds like it could make it into the next build? If so, thanks!

@jml it is unlikely to be in the next beta release and still TBC if it will be in 3.5 We have a huge number of requests right now!
-
@T3P3Tony No worries, I figured! But I will keep my fingers crossed
-
are there any news about the custom CAN-FD Message ? I already have my own hardware running with the duet 3 and would like to do the interaction with CAN-FD.

@OpenDev I should be able to implement this in time for the next 3.6 beta. I'll need to choose the parameter letters and their associated types. I'm thinking P unsigned integer, R and S signed integer, E and F floating point, and C string. Would this meet your needs?

Hello dc42,
oh, great to hear. I think these data types could be good for testing, I'm looking forward to it. Thank you!

@OpenDev this is implemented in 3.6beta3. https://reprap.org/wiki/G-code#M655:_Send_request_to_custom_CAN-connected_expansion_board
