## Disclaimer
This is a **fork** of the popular [Tonuino-project](https://github.com/xfjx/TonUINO) which means, that it only shares the basic concept of controlling a music-player by RFID-tags and buttons. **Said this I want to rule out, that the code-basis is completely different and developed by myself**. So there might be features, that are supported by my fork whereas others are missing or implemented differently. For sure both share that it's non-profit, DIY and developed on [Arduino](https://www.arduino.cc/).

## Wiring (2 SPI-instances)
A lot of wiring is necessary to get ESP32-Tonuino working. After my first experiments I soldered the stuff on a board in order to avoid wild-west-cabling. Especially for the interconnect between uC and uSD-card-reader make sure to use short wires (like 10cm or so)! Important: you can easily connect another I2S-DACs but just connecting them in parallel to the I2S-pins (DIN, BCLK, LRC). This is true for example if you plan to integrate a [line/headphone-pcb](https://www.adafruit.com/product/3678). In general, this runs fine. But unfortunately this board lacks of a headphone jack, that takes note if a plug is inserted or not. Best way is to use a [headphone jack](https://www.conrad.de/de/p/cliff-fcr1295-klinken-steckverbinder-3-5-mm-buchse-einbau-horizontal-polzahl-3-stereo-schwarz-1-st-705830.html) that has a pin that is set to GND, if there's no plug and vice versa. Using for example a MOSFET-circuit, this signal can be inverted in a way, that MAX98357.SD is pulled down to GND if there's a plug. Doing that will turn off the speaker immediately if there's a plug and vice versa. Have a look at the PCB-folder in order to view the detailed solution. Here's an example for such a [headphone-pcb)(https://github.com/biologist79/Tonuino-ESP32-I2S/tree/master/PCBs/Headphone%20with%20PCM5102a%20and%20TMD1308) that makes use of GND.

## Starting Tonuino-ESP32 first time
After plugging in it takes a few seconds until neopixel indicates that Tonuino is ready (by four (slow) rotating white LEDs). If uC was not able to connect to WiFi, an access-point (named Tonuino) is opened and after connecting this WiFi, a [configuration-Interface](http://192.168.4.1) is available via webbrowser. Enter WiFI-credentials + the hostname (Tonuio's name), save them and restart the uC. Then reconnect to your "regular" WiFi. Now you're ready to go: start learning RFID-tags via GUI. To reach the GUI enter the IP stated in the serial console or use the hostname. For example if you're using a Fritzbox as router and entered tonuino as hostname in the previous configuration-step, in your webbrowser tonuino.fritz.box should work. After doing the rfid-learning, place your RFID-tag next to the RFID-reader and the music (or whatever else you choosed) should start to play. While the playlist is generated, fast-rotating LEDs are shown to indicate that Tonuino is busy. The more tracks a playlist/directory contains the longer this step takes. <br>

Please note: hostname can be used to call webgui or FTP-server. I tested it with a Fritzbox 7490 and worked fine. Make sure you don't use a name that already exists in you local network (LAN).
## WiFi
WiFi is mandatory for webgui, FTP and MQTT. However, WiFi can be temporarily or permanently disabled. There are two ways to do that:
* Use a special modification-card that can be configured via webgui
* Press previous + next-button in parallel shortly
This toggles the current WiFi-status which means: if it's currently enabled, it will be disabled and vice versa. Please note: change is *not effective until the next reboot* but will remain until you change it again. Having Wifi enabled is indicated in idle-mode (no playlist active) with four white slow rotating LEDs whereas disabled WiFi is represented by those ones colored blue.
## After Tonuino-ESP32 is connected to your WiFi
After connecting the Tonuino to your WiFi, the 'regular' Webgui is available at the IP assigned by the router. Using this GUI, you can configure:
