{{bloc-etroit|text=Pin numbering of the BCM2835 GPIO port(s) on the Raspberry Pi has been a source of great confusion since the designs for the Pi were first published. In the early days (even beofre hardware was avalable) the default usable GPIO pins were simply referred to by number as GPIO0 through GPIO7. Additionally there were pins for other purposes, SPI, I2C and serial. This was highlighted on the original image on the Raspberry Pi Wiki site too.

{{bloc-etroit|text=La numérotation des broches de(s) port(s) GPIO du BCM2835 GPIO sur le Raspberry Pi est source d'une grande confusion et ce depuis la publication des informations de conception du Pi.  

 

Au début (avant même la disponibilité de la première version matérielle) les broches GPIO utilisaient tout simplement des référencées numérotées sous GPIO0 à GPIO7.  

 

Par la suite, d'autres broches furent ajoutées pour d'autres utilisations générales, SPI, I2C et port série. Cela fut également mis en avant sur Wiki du Raspberry Pi.

So when initially writing wiringPi, I chose to have the same default pin numbering scheme and numbered them from 0 upwards. This is no different to how the Arduino operates – “Pin 13″ on the Arduino is Port B, bit 5 for example. The underlying hardware definitions are hidden by a simplified numbering scheme. On the Pi, using wiringPi, pin 0 is BCM_GPIO pin 17 for example)
