esp-idf-tea5767

TEA5767 FM Stereo Radio Driver for esp-idf.
I ported from here.

Software requirements

ESP-IDF V5.0 or later.
ESP-IDF V4.4 release branch reached EOL in July 2024.

Hardware requirements

• TEA5767 FM Stereo Radio Module
  I bought this on AliExpress about $4.

  

• External antena
  The module has a standard antenna, but if you want to use it in a room, you need a long antenna.
  With a long antenna, you can get more signals.
  I used this extension antenna.
  This is used by hanging it on a curtain rail.
  I bought this for $5.
  

• Speaker
  A speaker with a 3.5mm 3-pole mini plug input is required.
  I bought this for $5.
  

• Wire Cable
  3.5mm 3-pole mini plug Male to Male wire cable.
  Used to connect to speakers.

Installation

git clone https://github.com/nopnop2002/esp-idf-tea5767
cd esp-idf-tea5767/withKey
idf.py menuconfig
idf.py flash

When using the USB port provided by the USB Serial/JTAG Controller Console, you need to enable the following line in sdkconfig.

CONFIG_ESP_CONSOLE_USB_SERIAL_JTAG=y

Configuration for Radio

• CONFIG_SCL_GPIO
  GPIO number(IOxx) to SCL.
• CONFIG_SDA_GPIO
  GPIO number(IOxx) to SDA.
• CONFIG_FM_BAND
  In US/EU it ranges from 87.5 MHz to 108 MHz.
  In Japan it ranges from 76.1 MHz to 94.9 MHz.
  Used when wrapping in a search.

Wireing

TEA5767		ESP32	ESP32-S2/S3	ESP32-C2/C3/C6
SCL	--	GPIO22	GPIO4	GPIO6	(*1)
SDA	--	GPIO21	GPIO3	GPIO5	(*1)
GND	--	GND	GND	GND
VCC(*2)	--	3.3V	3.3V	3.3V

(*1)
You can change it to any pin using menuconfig.

(*2)
The PCB marking is +5V, but it works at 3.3V.
