ESP32-S2 CircuitPython Getting Started

Fix for Open GL on Intel HD Graphics 3000 - Windows 10

The drivers for Intel HD Graphics 3000 in Windows 10 does not expose all Open GL capabilities of the GPU. So software relying on Open GL features not present in Open GL 1.1 will not work. Using older versions of Windows or Linux might work since the chip have more features than the driver exposes.

The fix is to add a compatibility shim using the Windows ADK software.

1. Download and install Windows ADK

Markdown - Resize pictures in GitHub

I found that the "best" way is to use HTML, as it works both in Readme/.md files and also in comments (within Issues, Gist...)

E.g. when adding/editing a comment (within Issues, Gist...) :

Upload the picture by drag-and-drop in the text field
replace ![image](https://your-image-url.type) with <img src="https://your-image-url.type" width="100" height="100">

As mentioned by @cbestow (thanks!), it's not mandatory to set both width and height. If only one is set, the other will be adjusted accordingly to preserve the aspect ratio of the image.

Save these files as ~/.config/systemd/user/some-service-name.*

Run this now and after any modifications: systemctl --user daemon-reload

Try out the service (oneshot): systemctl --user start some-service-name

Check logs if something is wrong: journalctl -u --user-unit some-service-name

Start the timer after this user logs in: systemctl --user enable --now some-service-name.timer

	# synthio_midi_synth.py - pretty usable MIDI-controlled synth using synthio in CircuitPython
	# 11 May 2023 - @todbot / Tod Kurt
	# Uses cheapie PCM5102 DAC on QTPY RP2040
	# Video demo: https://www.youtube.com/watch?v=N-PbbWWDE6k
	# Features:
	# - midi velocity controls attack rate (gentle press = slow, hard press = fast)
	# - notes have small random detune on all oscillators to reduce phase stacking
	# - adjustable number of detuned oscillators per note 1-5 (midi controller 83)
	# - five selectable waveforms: saw, squ, sin, noisy sin, noise (midi controller 82)
	# - vibrato depth on mod wheel (midi controller 1)
