TEA5767 FM Stereo Radio Driver for esp-idf.
I ported from here.
ESP-IDF V4.4/V5.x. ESP-IDF V5.0 is required when using ESP32-C2. ESP-IDF V5.1 is required when using ESP32-C6.
TEA5767 FM Stereo Radio Module. I bought this on AliExpress about $4.
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 an AC power cable as extended antena.
git clone https://github.com/nopnop2002/esp-idf-tea5767
cd esp-idf-tea5767
idf.py set-target {esp32/esp32s2/esp32s3/esp32c2/esp32c3/esp32c6}

TEA5767 | ESP32 | ESP32-S2/S3 | ESP32-C2/C3/C6 | ||
---|---|---|---|---|---|
SCL | -- | GPIO22 | GPIO4 | GPIO6 | (*1) |
SDA | -- | GPIO21 | GPIO3 | GPIO5 | (*1) |
GND | -- | GND | GND | GND | |
VCC | -- | 3.3V | 3.3V | 3.3V | (*2) |
(*1) You can change it to any pin using menuconfig. But it may not work with other GPIOs.
(*2) The PCB marking is +5V, but it works at 3.3V.
Refer to tea5767.h.
Search radio station Press the + key to search for radio stations upwards. Press the - key to search for radio stations downwards.
Preset radio station Press the * key to record the current radio station in NVS. At boot time, it read from NVS and set to the current Radio station.
Change frequence Press the D key to decrease the frequence by -1.0Mhz. Press the U key to increase the frequence by +1.0Mhz. Press the d key to decrease the frequence by -0.1Mhz. Press the u key to increase the frequence by +0.1Mhz.
