# HackadayVectorscopeHacks



### Hacks so far

#### CircuitPython

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

* [fake_vectorscope1.py](./circuitpython/fake_vectorscope1.py)

  --  ([video demo](https://mastodon.social/@todbot/111275574436711965))

    using multiple `vectorio` objects to make the phospher trails, can't have too many.

* [fake_vectorscope2_lissajous.py](./circuitpython/fake_vectorscope2_lissajous.py)

  --  ([video demo](https://mastodon.social/@todbot/111279891762130663))

    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](./arduino/fakey_vectorscope_lissajous/fakey_vectorscope_lissajous.ino)

  -- ([video demo](https://mastodon.social/@todbot/111281415284194368))

    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](./micropython/gc9a01_test.py)
