# m5stack-chipstream
This is a test to port [C++'s ymfm and Rust's vgmplay](https://github.com/h1romas4/libymfm.wasm) to ESP32(Xtensa).
Still slow and impractical, depending on the sound chip you choose.
## Environment
- [M5Stack Core2](https://docs.m5stack.com/en/core/core2) (ESP32 PSRAM 4MB+4MB)
- [M5Stack RCA Module](https://docs.m5stack.com/ja/module/RCA%20Module%2013.2) (I2S PCM5102APWR)
## Demo
🎥 https://twitter.com/h1romas4/status/1629345305861947393
## TODO
- [x] The transfer of PCM waveforms from Rust to C is shifted depending on the memory state. (Is it due to int16_t alignment?)
- [x] I may be using the ring buffer or I2S DMA incorrectly. The process slows down from the same time, independent of the waveform generation process time.
- [ ] Player control is not complete. May stop when transitioning to next song.
- [ ] There is no interface to stop playback.
## Build
@see [.github/workflows/build.yml](https://github.com/h1romas4/m5stack-chipstream/blob/main/.github/workflows/build.yml#L26-L59)
### Setup
- [Setup ESF-IDF v4.4.6](https://docs.espressif.com/projects/esp-idf/en/v4.4.6/esp32/get-started/index.html#installation-step-by-step)
get_idf
```
alias get_idf='. $HOME/esp/esp-idf/export.sh'
```
```
$ get_idf
Detecting the Python interpreter
... snip ...
Done! You can now compile ESP-IDF projects.
Go to the project directory and run:
idf.py build
$ echo ${IDF_PATH}
/home/hiromasa/devel/toolchain/esp/esp-idf
$ xtensa-esp32-elf-gcc -v
Using built-in specs.
