To the average microcontroller, Ethernet networks are quite a step up from the basic I2C, SPI and UART interfaces, requiring either a built-in Ethernet MAC or SPI-based MAC, with tedious translation ...
Binary FSK(Frequency Shift Keying) and PSK(Phase Shift keying) are extensively used in telecommunication for digital data transmission. FSK/PSK modulator circuits usually employ analogue components ...
The universal asynchronous receiver/transmitter (UART) is an old friend to embedded systems engineers. It's probably the first communications protocol that we learn in college. In this article, we ...
