# flipperzero-gpioreader
2+
3+
![image info](./gpioreader.png)
4+
5+
This is a fork of the `gpio` app built into the flipper, with added functionality to read GPIO inputs.
6+
7+
Supports pulling high or low.
8+
9+
Does not (yet) support analog reads.
10+
11+
Installation instructions (Linux):
12+
13+
- Clone the following repo: https://github.com/flipperdevices/flipperzero-firmware
14+
- Clone this repo into flipperzero-firmware/applications_user
15+
- Plug in your FlipperZero
16+
- Run `./fbt launch_app APPSRC=flipperzero-gpioreader` from within the flipperzero-firmware folder
