This is a playground (and dump) of stuff I made, modified, researched, or found for the Flipper Zero.
There's a lot of everything in here, from customized apps, BadUSB scripts, hardware specs for modders, GPIO interface shenanagains and interface pinouts, hardware troubleshooting, sound and music stuff, and sub-GHz captures and dissections for just about everything. It's an impressive collection.
piscope is a logic analyser (digital waveform viewer) for the RasPi. It shows the state (high or low) of selected GPIO pins in real-time. Uses the services of the pigpio library. pigpio needs to be running on the Pi whose GPIO are to be monitored. The pigpio library may be started as a daemon.
Install pigpiod on the RasPi: sudo apt-get install pigpiod pigpio-tools
Install PyScop on your workstation: yay -S pyscope
Start pigpiod: sudo pigpiod
Run pyscope on your workstation
export PIGPIO_ADDR=raspi

This GPIO Pinout is designed to be both a quick and interactive reference to the Raspberry Pi GPIO pins, plus a comprehensive guide to your Raspberry Pi's GPIO interfaces. It also includes dozens of pinouts for Raspberry Pi add-on boards, HATs and pHATs.
