DIY Instructions

1. Clone the repository:

   git clone https://github.com/lemariva/uPyM5Echo.git

2. Rename the file config.sample.py to config.py.
3. Create three wav files and rename them as audio_nr0.wav, audio_nr1.wav, audio_nr3.wav (you can use mine files, they are inside the audios folder). The files should be mono and the sample frequency 44.1kHz. If you want another frequency, you can modify the parameter SAMPLES_PER_SECOND = 44100 inside the main.py file.
4. Upload the py and wav files using VSCode and the PyMakr Extension. You may need to modify the option "sync_file_types":"py", to "sync_file_types":"py,wav", inside the file pymakr.conf to upload the wav files. The size of the files together should not be greater than 3MB, otherwise you'll get an error by uploading. If you want to, you can upload the wav files separately using the adafruit-ampy Python extension.

You can then connect to the M5Stack via Bluetooth using e.g., the BLE Scanner app and set the BLE Custom Characteristic to 01, 02, or 03 (Byte Array) to play different tracks.

The record and play example, which is shown in the video, results from using the micro_record_play.py file.
