* Instructions for installing the Android app and Pico firmware, connecting the Pico to your Android device and connecting the Scoppy oscilloscope to your signal source
* Listing of the GPIOs used by the scoppy-pico firmware and a description of their functions
[Analog Front-End](./wiki/Analog-Front-End)
* Design and build an Analog front-end to your Scoppy Oscilloscope so that you can measure different voltage ranges (ie. different to the 0-3.3V range of the RPI Pico ADC inputs).
Scoppy powered oscilloscopes are available for purchase at the [FHDM Store](https://store.fhdm.xyz/), [Tindie](https://www.tindie.com/stores/fhdm_tech/) and [Elecrow](https://www.elecrow.com/dso-500k-oscilloscope.html)
