Serial data transmission input-output delay with Raspberry Pi
问题 The Goal: Drive several servo/RC motors wireless from one pi to another pi. In essence, I want to build a RC remote control using a pi, with a second pion the receiver end. Now I have a serial transmission over a RF link module that is stable and has very few corrupt entries. The serial transmission has a max baud rate of 4800 due to the RF link module. Problem: It seems there is a 2-4 seconds difference between the transmitter pi printing values and the receiver pi printing values. I cannot
