UART Communication Protocol
UART (Universal Asynchronous Transmitter Receiver), this is the most common protocol used for full duplex serial communication. It is a single LSI (large scale integration) chip designed to...
RS232 Protocol
Historically, RS232 Communication protocol is an old serial communication protocol developed by EIA (Electronics Industry Alliance)/TIA (Telecommunications Industry Association)-232 in the year 1962. Modern hardware designs...
SPI interface, in depth
La connessione SPI
SPI (Serial Peripheral Interface) è uno standard per lo scambio dati con una ...
SPI interface, the basics
La traccia superiore è la linea dei dati, la traccia media è il clock e la traccia inferiore è il chip-select. La sovrapposizione blu sulla traccia dei...
Digital trimmer
A resistor is an electrical device that resists the flow of electrical current. In the digital era, we can find a variety of “digital resistors” for our...
SPI versus I2C
Interfacce seriali sincrone
Le interfacce seriali sincrone sono caratterizzate dalla presenza di un segnale di sincronizzazione (clock)
che determina la cadenza con cui i dati transitano...

RS232 Protocol, as UART application
Historically, RS232 Communication protocol is an old serial communication protocol developed by EIA (Electronics Industry Alliance)/TIA (Telecommunications Industry Association)-232 in the year 1962. Modern hardware designs...
Protected: BJT for MICROs
Recently I got an unusual query from a newbie microcontroller hobbyist on how to drive an electromagnetic relay using a bipolar junction transistor (BJT). Admit it, analog...
UART interface
Remember when printers, mice, and modems had thick cables with those huge clunky connectors? The ones that literally had to be screwed into your computer? Those devices were probably...
