Web13 dec. 2024 · Asynchronous serial communication is sometimes referred to as Transistor-Transistor Logic (TTL) serial, where the high voltage level is logic 1, and the low voltage equates to logic 0. Almost every microcontroller on the market today has at least one Universal Asynchronous Receiver-Transmitter (UART) for serial communication. WebMore formally RS232 is an asynchronous communication protocol that lets you transfer data between electronic devices. Basically it can transfer a single byte of data over a serial …
