What is BCM, and why is it used in a Raspberry Pi? - Quora

WebThere are three ways to describe pins, WiringPi, BCM, and BOARD. I'll be referencing the handout labeled 02_02_GPIOpins. Here's an example. The top right pin of the GPIO can … WebBCM pin numbering uses the GPIO port numbers assigned to the available GPIO pins by the Broadcomm system-on-a-chip on which the Raspberry Pi is based. Wiring Pi pin numbering is a scheme introduced by the Wiring Pi library, and is based on a similar scheme used by Arduino systems. WebJul 18, 2024 · You can choose between either numbering system using RPi.GPIO’s setmode function: GPIO.setmode (GPIO.BOARD) GPIO.setmode (GPIO.BCM) If you try to assign a pin before setting one of these modes, Python returns an error. I personally prefer the Broadcom numbering. It’s clearer which pins are GPIO, ground, or power. cube tennis
