headers-list

Prints physical headers pins and the associated functionality of each pin.

• Looking for the GPIO pins per functionality? Look at gpio-list.
• Looking for periph drivers loaded? Look at periph-info.

Example

Print the pins per their hardware location on the headers. This uses an internal lookup table then query each pin. Here's an example on a host with two SPI host and lirc enabled:

$ headers-list
AUDIO: 2 pins
  Pos  Name    Func
  1    GPIO41  PWM1_OUT
  2    GPIO40  PWM0_OUT

HDMI: 1 pins

  1    GPIO46  In/High

P1: 40 pins

Overview

headers-list prints out the headers as found on the computer and print the functionality of each pin.
