Hi everyone,
I have a customer that want to use serial (over USB) to communicate from a PC with an ARM chip. They want the connection to be reliable with some level of error checking. I have access to Keil's MDK-ARM and was wonder if it's worth using their TcpNet stack with TCP over PPP. Is this overkill for something like this? Should I resort to creating my own protocol or use something similar to HDLC or Modbus? I would be designing and implementing both the PC and ARM sides.
