Serial communication

Serial communication is a widespread way of transmitting data between two devices.



Advantages:

  • Communication with just two wires: Rx - Tx
  • Error check: parity bit
  • Asynchronous communication


Disadvantages:

  • The maximum data range per packet is just 9 bits
  • It does not support multiple devices
