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

• Use headers-list -help for help
• Use -f to print the alternative functions each pin can take

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

Overview

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