Hey guys, I was thinking that it can be useful to add a library page about various ways of transmitting digital information over the wires in both serial and parallel connections, synchronous / asynchronous, full-duplex / half-duplex, etc.

For example:

Serial

1-wire for data and 1 wire for clock results in synchronous half-duplex serial transmission 2-wire for data and 1 wire for clock results in synchronous full-duplex serial transmission (Hardware example: SPI) 2-wire for data and no clock for asynchronous full-duplex serial transmission (Hardware example: USART) 1-wire for data and clock (like USB), data is encoded using special algorithm, making the USB data like almost always switch every clock pulse, providing serial information and means to adjust clock differences.

I want to hear more examples if you can think of any :)

Sounds like a great idea. If you cover UART, SPI, and TWI (I2C) bus you have probably covered most of the inter chip communication you can think of doing.

Love the idea. Please go for it
