GPIO_led_image

A little fun software in C++ to "display" an image to an RGB led.

How it works?

Run as root the software with as an argument a path to an image file (PNG, JPG, etc...). For the first run, it will create a configuration file /etc/gpio_led_image.txt, the 3 uncommented lines are the R, G and B GPIO pins of the led, defaults are: R=0, G=2 and B=3.

When you launch the configured software with an image, it will read the image and display each pixel one after the other for 150ms, it's just that, just for fun.

Libraries used

• wiringPi -> For GPIO manipulation.
• lambdacommon -> Colored terminal output, int parsing, file management...
• stb_image -> For image reading.

Build

Just build it with cmake and make!
