A program for the Raspberry Pi Pico written in C to output the current temperature in Celsius as binary numbers.

The LEDs must be connected to the following pins:

• For the integer digits: 0, 1, 2, 5, 6, 7
• For the decimal places: 10, 13, 14, 15

To compile the program properly you need the raspberry-pico-sdk (it's also available in the AUR) and cmake. Create a folder for the build and make the program like this:

mkdir build
cd build
cmake ..
make

To install it, simply connect the pico to your PC while pressing the button on the pico, mount it and copy the .uf2 file into the mount directory. Now you can sync and umount /path/to/mnt/dir. The thermometer will start automatically if you don't press the button on startup.
