GPIO , SPI, I2C, I2S etc

introduction of JetPack 4.3 ( ( L4T 32.3.1) brings with it a new tool, Jetson-IO. All of the Jetson developer kits include a 40-pin GPIO expansion header. Many of the pins can be used either as General Purpose I/O (GPIO) or Special Function I/O (SFIO). SFIO are functions such as I2C, I2S, SPI, and so on
