tio VS arduino-audio-tools

Tio is a user-friendly CLI tool for straightforward serial device management. Allows you to connect to serial TTY devices and perform basic input/output operations through a configuration file or via direct commands. bh0 adds, "I use tio for serial/console on my Mac. Tio is awesome."

tio. https://github.com/tio/tio. Super simple no frills program. It's gnu screen minus the stackoverflow searches. This is what you want.

In my case I use either VSCodium (OSS version of VS Code) or Emacs as my text editor, and "tio" (https://github.com/tio/tio) as the serial comms program in a terminal window. "tio" is great because it will auto-connect when a device is reset. But if you don't like command-line, PuTTY on Windows and CoolTerm on MacOS are good serial terminal apps.

I highly recommend tio: https://github.com/tio/tio

Have you found Phil's audio tools for Arduino, they work great on ESP32. https://github.com/pschatzmann/arduino-audio-tools

I use an ESP32-A1S board for that. I use this project https://github.com/pschatzmann/arduino-audio-tools/ and the platformIO vscode plugins.

Have a look at this example to see how easy using that library is :

Check out arduino-audio-tools and other libraries it can make use of, such as ESP32-A2DP. It's tailored towards ESP32 devices, but also supports the RP2040 and others.

The ESP32-A1S is a fun toy to program with that lib https://github.com/pschatzmann/arduino-audio-tools on that cheap kit: https://docs.ai-thinker.com/en/esp32-audio-kit

I have already successfully generated a fairly good 40khz sine wave with the internal DAC using this library: https://github.com/pschatzmann/arduino-audio-tools. I have also played an uploaded MP3 file, but I cannot figure out how to implement FM specifically to modulate the two waves together.

The PCM5102A does a great job. You can get modules for a few dollars, and can even get hat specifically designed for the RP2040. I've got one to work with an ESP32 with the Arduino Audio Tools library. Andreas Spiess has a great video on the subject.

Been wanting to do this myself a good source for this is this linkhttps://github.com/pschatzmann/arduino-audio-tools

Normally I’d recommend one of my YouTube videos :) - but actually this guy has done an amazing job: https://github.com/pschatzmann/arduino-audio-tools

I got it to play both MP3 and WAV files using ESP-audioI2S and arduino-audio-tools, though only single files. AAT uses player.copy() and the other uses audio.loop(), both can call files by name but only once, as far as I can tell.

https://github.com/pschatzmann/arduino-audio-tools and you can program it with arduino
