UART, or Universal Asynchronous Receiver Transmitter, is a very popular communications protocol for embedded systems because it is simple and universal. May not be able to transfer large amounts of data or communicate directly via USB, but it is so popular that there are devices that perform USB conversion and even pass wireless communication protocols (XBee). Anyway, we delve into UARTs, how they work, and how to create our own software, specifically in Assembly, using our ever-present PIC10F200. We really enjoyed this tutorial and hope you enjoy watching it as much as we enjoyed making it.

These tutorials start to get so complicated that the videos remain quite high level. If you want the code you can copy and paste or if you need a little more time to go through everything line by line, check out the written tutorial this video is based on: https://www.circuitbread.com/tutorials /communicating-with-a-pc-with-uart—part-11-microcontroller-basics-pic10f200
