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 project illustrates the serial interfacing of Hitachi compatible 2×16 LCD modules with PIC16F84 or PIC16F628 microcontroller unit. Before doing serial interfacing LCD with PIC microcontroller, it ...

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 ...

I know you’ve heard of both synchronous and asynchronous communications. But do you really know the differences between the two? Serial communication was used long before computers existed. A ...
