We have a raspberry pi that plays a video loop that we want to tie into some control boards.
We still need to develop the control boards, but would like to use RS485 to keep the connectivity simple.
We will provide all the information regarding the functionality, so you can write the code to make it all function.
The code will eventually be embedded into a bigger project on the same raspberry pi, but we need help with external board functions and comms development.
The final delivery will need to include:
1. RS485 interface circuits
2. communication protocols for all the boards
3. based on the information we provide, all the data strings to make it all work (not sure what the correct terminology is) :)
If you have electronics development experience as well, this will help and we may be able to increase the budget if you can provide more assistance.
We can use FTDI's but we're open to suggestions for best practice. Whatever we do will need to be a custom board, but we can design that once we have the schematics.
Finally, we'd like assistance with testing and debugging once it's built.
See a basic outline of the design attached.
