## Hardware
#### Required:
**ESP32 board**: https://aliexpress.ru/item/32847027609.html \
**I2S DAC**, roughly like this one: https://aliexpress.ru/item/1005001993192815.html \
https://aliexpress.ru/item/1005002011542576.html
#### Optional:
##### Displays
- **ST7735** 1.8' or 1.44' https://aliexpress.ru/item/1005002822797745.html
- or **SSD1306** 0.96' I2C https://aliexpress.ru/item/1005001621806398.html
- or **Nokia5110** 84x48 SPI https://aliexpress.ru/item/1005001621837569.htmlz

##### Controls
Three tact buttons or Encoder or all together

_\* Any free pin, configured in options.h_ \
_\** GPIOs 34-39 don't have software pullup/down functions. For encoder/buttons use an external pullup resistor, 10 kOhm works here_

## Dependencies
#### Libraries:
Adafruit_GFX, Adafruit_ST7735\*, Adafruit_SSD1306\*, Adafruit_PCD8544\*, (\* depending on display model), ESP32Encoder, OneButton, [ESPAsyncWebServer](https://github.com/me-no-dev/ESPAsyncWebServer), [AsyncTCP](https://github.com/me-no-dev/AsyncTCP)
#### Tool:
[ESP32 Filesystem Uploader](https://randomnerdtutorials.com/install-esp32-filesystem-uploader-arduino-ide/)

## Hardware setup
Hardware is connected in the **[options.h](yoRadio/options.h)** file. \
_so that the settings are not overwritten when updating git, you need to put the file **myoptions.h** ([exsample](exsamples/myoptions.h)) in the root of the project and make settings in it_
````
/* DISPLAY MODEL
 * 0 - DUMMY
 * 1 - ST7735
 * 2 - SSD1306
 * 3 - NOKIA5110
 */
#define DSP_MODEL  1
````
The ST7735 display model is configured in the file [src/displays/displayST7735.cpp](yoRadio/src/displays/displayST7735.cpp)
````
#define DTYPE INITR_BLACKTAB // 1.8' https://aliexpress.ru/item/1005002822797745.html
//#define DTYPE INITR_144GREENTAB // 1.44' https://aliexpress.ru/item/1005002822797745.html
````
Rotation of the ST7735 display is configured in the file [src/displays/displayST7735.h](yoRadio/src/displays/displayST7735.h)
````
#define TFT_ROTATE 3 // 180 degress
````
If there is a noisy line on one side of the screen, then in Adafruit_ST7735.cpp:
````
  // Black tab, change MADCTL color filter
  if ((options == INITR_BLACKTAB) || (options == INITR_MINI160x80)) {
    uint8_t data = 0xC0;
    sendCommand(ST77XX_MADCTL, &data, 1);
    _colstart = 2; // ← add this line
    _rowstart = 1; // ← add this line
  }
````

## Quick start
1. In ArduinoIDE - upload sketch data (Tools→ESP32 Sketch Data Upload)
2. Upload the sketch to the board ([example of the board connection](images/board.jpg))
3. Connect to yoRadioAP acces point with password 12345987, go to http://192.168.4.1/ configure and wifi connections.  \
_\*this step can be skipped if you add WiFiSSID WiFiPassword pairs to the [yoRadio/data/data/wifi.csv](yoRadio/data/data/wifi.csv) file (tab-separated values, one line per access point) before uploading the sketch data in step 1_
4. After successful connection go to http://\<ipaddress\>/ , add stations to playlist (or import WebStations.txt from KaRadio)
5. Well done!

**localization:**
Если Adafruit_GFX ещё не русифицирована, русифицировать её, заменив файл Arduino/libraries/Adafruit_GFX_Library/glcdfont.c файлом [yoRadio/fonts/glcdfont.c](yoRadio/fonts/glcdfont.c)
