Serial data transmission answers all the above problems, most especially the first one, as cost and limited pins are common issues in microcontroller system design. Crosstalk is also an issue due to the proximity of the wires.It is susceptible to clock skew, which limits the speed of transmission to the slowest of the links.The greater number of wires limit it to shorter transmission distances.It needs more wires and therefore can be more expensive to implement.Parallel data transmission is faster than serial transmission but with a number of disadvantages: In contrast, parallel communication is where data bits are sent as a whole. Serial communication is the process of transmitting data one bit at a time. ![]() ![]() 6 Serial with Embedded Linux (Beaglebone Black/Raspberry Pi).
