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

Dependencies
Libraries:
Adafruit_GFX, Adafruit_ST7735*, Adafruit_SSD1306*, Adafruit_PCD8544*, (* depending on display model), ESP32Encoder, OneButton, ESPAsyncWebServer, AsyncTCP
Tool:
Hardware setup
Hardware is connected in the options.h file.
so that the settings are not overwritten when updating git, you need to put the file myoptions.h (exsample) 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
#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
#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
- In ArduinoIDE - upload sketch data (Tools→ESP32 Sketch Data Upload)
- Upload the sketch to the board (example of the board connection)
- 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 file (tab-separated values, one line per access point) before uploading the sketch data in step 1 - After successful connection go to http://<ipaddress>/ , add stations to playlist (or import WebStations.txt from KaRadio)
- Well done!
