README.mdAudio Playback on a CH32V00X
Example code for playing audio on a CH32V006 using PWM and DMA.
Hardware
Small speaker connected to PC3 though a large capacitor(in series), at least 10uF.
The example PCB is designed for experimentation, therefore it also includes USB, SPI-FLASH and a can use the internal OPAMP as a second order low-pass filter. All of these features are optional.
Getting Started
- Get everything:
git clone --recurse-submodules- Build tools:
make tools- Convert audio file to code:
./tools/wav2code beep-boop.wav > samples.h- Build and flash:
make- Run and interract with the program:
make monitor[!WARNING] Make sure the audio file is encoded as 16-bit signed PCM, mono, and 32kHz sample rate(this can be adjusted).

You should order with ENIG (electroless nickel immersion gold) plating. While the cartridge will work with HASL you will getter contact with ENIG and it is less prone to wearing down.

Questions
How big is the Ch32v006 audio PCB?
It measures 47 × 21 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ch32v006 audio use?
18 parts, built around the W25Q16JVSSIQ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ch32v006 audio KiCad files?
From the BogdanTheGeek/ch32fun-audio repository on GitHub, at the commit this page was made from: the board is hardware/ch32v006_audio.kicad_pcb and its schematic hardware/ch32v006_audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ch32v006 audio design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
