UART, or Universal Asynchronous Receiver Transmitter, is a very popular embedded systems communication protocol because it's simple and universal. Perhaps not capable of transferring large amounts of data or directly communicating over USB, it is popular enough that there are devices that do USB conversion, and even pass-through wireless communication protocols (XBee). Either way, we drill down into UARTs, how they work, and how we can create our own in software, specifically in Assembly, using our ever present PIC10F200. We really enjoyed this tutorial and hope that you enjoy watching it as much as we did making it.
These tutorials are starting to complicated enough that the videos are staying pretty high-level. If you want the code that you can copy and paste or need some more time going through everything line by line, check out the written tutorial that this video is based off of: [ Ссылка ]
