In digital electronics, a tri-state or three-state buffer is a type of digital buffer that has three stable states: a high output state, a low output state, and a high-impedance state. In the high-impedance state, the output of the buffer is disconnected from the output bus, allowing other devices to drive the bus without ... WebSep 2, 2024 · They are different pins. (2) If you don't want to use the on board hardware CS pins, eg CS0 of SPI 0, 0, or CS1 of SPI 0, 1. Then you just do not hardware connect the corresponding pin to the CS chip of the SPI (eg. sensor) device/chip/module. In stead you use you own software to use any other GPIO to fake the new CS pin. rayleigh afternoon tea
