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.

cd esp-idf-tea5767

- 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 MHz to 91 MHz.
Used when wrapping in a search.
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. -
