Hi, I'm with a similar question. I am implementing a modbus for code generation to a PIC18. The problem I have is that I can not reset the state machine when the dead time of 3.5 characters has elapsed, around 4 ms. I do this with a timer. For other blocks, I manage to generate codes at different execution times in multitasking mode, and I have no problems. It would even be very good if simulink people implemented blocks for the modbus protocol and that allows c / c ++ code generation.
Thanks.
