## Known bugs
* Some webstreams don't run. Guess it's a combination of saturated connection-pool and lack of heap-memory. Works probably better if ESP32-WROVER is used, as this chip has PSRAM. Advice: Don't enable modules (e.g. MQTT) if you don't need them as this could save memory.

The basic idea of Tonuino is to provide a way, to use the Arduino-platform for a music-control-concept that supports locally stored music-files without DRM-restrictions. This basically means that RFID-tags are used to direct a music-player. Even for kids this concept is simple: place an RFID-object (card, character) on top of a box and the music starts to play. Place another RFID-object on it and anything else is played. Simple as that.
## Hardware-setup
The heart of my project is an ESP32 on a [Wemos Lolin32 development-board](https://www.ebay.de/itm/4MB-Flash-WEMOS-Lolin32-V1-0-0-WIFI-Bluetooth-Card-Based-ESP-32-ESP-WROOM-32/162716855489). If ordered in China (Aliexpress, eBay e.g.) it's pretty cheap (around 4€) but even in Europe it's only around 8€. Make sure to install the drivers for the USB/Serial-chip (CP2102 e.g.). But probably it's besser to use it's successor: [Wemos Lolin D32](https://de.aliexpress.com/item/32808551116.html).

Or, if you're planning to hear webstreams regularly, [Wemos Lolin D32 pro](https://de.aliexpress.com/item/32883116057.html) might be a good decision. It comes with uSD-slot onboard and because of its ESP32-WROVER-B has PSRAM included. PSRAM is used as webstream-cache and might be used more intensively in future.

Having SD working is mandatory. So there are two modes available to access SD-cards: SPI and SD-MMC (1 bit).<br />
Advantages SD-MMC (1 bit) over SPI:
* Needs only three GPIOs (instead of four)
* It is almost twice as fast in FTP-transfer
So why using SPI if SD-MMC is better? The primary problem of SD-MMC is: you cannot choose different GPIOs. That doesn't sound bad but this can (depends on the ESP-develboard) be a problem because GPIO2 is pulled HIGH in SD-MMC-mode. And if that's the case, you'll probably not able to flash the firmware as the ESP32 doesn't enter flash-mode. Tested it with Lolin32 and had to remove SD's wire to GPIO2 until flash-mode was entered. As soon as flash-mode was entered, it's safe to re-connect it. So be advised: SD-MMC is nice and fast, but if you want to update the firmware and ESP32 is deeply burried in Tonuino's enclosure, this can be problem.
* It is almost twice as fast in FTP-transfer<br />
So why using SPI if SD-MMC seems to be better? The primary problem of SD-MMC is: you cannot choose different GPIOs. That doesn't sound bad but this can (depending on the uSD-card-reader-module) be a problem because maybe GPIO2 is pulled HIGH to 3.3V by a resistor. For example this is the case when using the reader-module named above in hardware-setup. It's a problem because if GPIO2 is pulled high, ESP32 doesn't enter flash-mode. As soon as flash-mode is entered, it's no longer a problem. However, this behaviour can be an issue if ESP32 is deeply "burried" in Tonuino's enclosure and you want to update its firmware. But fortunately there's a way to bypass this problem: remove the [pullup-resistor shown in the picture](https://raw.githubusercontent.com/biologist79/Tonuino-ESP32-I2S/master/pictures/Pullup-removal.jpg). It can be removed safely because if MMC-mode is set, pullup is done in software using `pinMode(2, INPUT_PULLUP);`.
## RFID: RC522 or PN5180?
RC522 is so to say the Tonuino-standard. It's cheap and works, but RFID-tag has to be placed near the reader. PN5180 instead has better RFID range/sensitivity and can read ISO-15693 / iCode SLIX2-tags aka 'Tonies'. Disadvantages: is a bit more expensive and needs more GPIOs (6 instead of 4). Refer PN5180's wire-section below for further informations.
