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
vectorioobjects to make the phospher trails, can't have too many. -
fake_vectorscope2_lissajous.py -- (video demo) drawing on
Bitmapwithout 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.
