Re: [GPIO numbering](/topic/2367/gpio-numbering)

In this example @Viswanadh-Chegu is able to find the offset for for J8 pin 12 but how would you do that for all the other connectors that might have gpio pins? 

I am specifically looking for J10 pin 6 but nonetheless I would like to learn the methodology

@tonygurney , please see the doc page regarding GPIO and the offset:

https://docs.modalai.com/voxl2-linux-user-guide/#gpios

specifically,

```
Starting SDK 1.2.X/System Image 1.7.3, GPIOs are exported by default in /sys/class/gpio, the GPIO have an offest of 1100 (e.g. GPIO 84 = 1184).
```
