Automatic baud-rate detection is desirable in many applications. Microchip’s standard USART module that the company embeds in most of its PIC microcontrollers lends itself to a simple and easily ...

A USART is more complex and can generate data in a form corresponding to many different standard protocols such as IrDA, LIN, Smart Card, Driver Enable for RS-485 interfaces, and Modbus, to name a few ...

There’s some extra detail with inverting the signal if, as most do, your USART idles high. But that’s really it. It’s a cute trick for when you’re desperate enough to need it.

The latest generation of PIC18F8680/6680 and PIC18F8585/6585 PICmicro flash microcontrollers (MCUs) integrate the company’s ECAN module, said to be a flexible, easy-to-use CAN 2.0B interface ...

We find it interesting that PIC and AVR programming is very common in hobby electronics but ARM doesn’t have nearly the same foothold. This is partly because there’s a knowledge barrier… ...
