When designing a multicontroller system, it is convenient to organize the communication between µCs via one wire line. Unfortunately, low-end µCs have no serial-interface capabilities like their more ...

The usual way send data from a microcontroller is either over RS-232 with MAX232 serial ICs, crystals, and a relatively ancient computer, or by bit-banging the USB protocol and worrying about driver ...

It’s not much of a stretch to assume that the majority of Hackaday readers are at least familiar with I2C. In fact, there’s an excellent chance that anyone who’s ever done more with an Arduino than ...

The UART, or universal asynchronous receiver-transmitter, is one of the most used device-to-device communication protocols. This article shows how to use a UART as a hardware communication protocol by ...

A bootloader makes it possible to update a product’s firmware in the field. Common communication interfaces like UART, I 2 C, SPI or USB can be used to update the firmware, which typically involves a ...
