HackadayVectorscopeHacks

Hacks so far

CircuitPython

Uses standard Raspberry Pi Pico build of CircuitPython with gc9a01 driver in Community Bundle.

• fake_vectorscope1.py -- (video demo) using multiple vectorio objects to make the phospher trails, can't have too many.

• fake_vectorscope2_lissajous.py -- (video demo) drawing on Bitmap without trying to erase, looks pretty good but no fading trails

Arduino

Uses standard arduino-pico core with Arduino_GFX library to drive the display.

• fakey_vectorscope_lissajous.ino -- (video demo) pretty good looking trails, but they fight with the grid lines

Micropython

Uses UF2 from https://github.com/russhughes/gc9a01_mpy but it seems pretty unstable, wiping out the entire flash contents and requiring a reinstall of Micropython. And the font mpy files provided do not work with the provided UF2.

• gc9a01_test.py
