GPIO Communication Protocols & Peripherals – UART, I2C, SPI, PWM, PCM, DAC & ADC

This is a general overview of the various communication protocols and peripherals that are available on embedded systems such as the Raspberry Pi and other SBCs and microcontrollers. In my next video I’ll be doing several hands on examples with sensors implementing some of the protocols I talk about today.
