There are various working C++ class based libraries for the RFM73 - both arduino and ESP-IDF. But my application is a C a...

Thanks for the reply. I have updated my code so that a touching the PLAY touchpad reduces my equalizer values and touching SET increases the values. I set a min allowed value of -20dB and a max allowed value of 0dB - limiting the values PLAY and SET can set. For my tests i set all 20 bands of the eq...

What is the range of values that are valid when setting the equalizer gain? audio_element_handle_t equalizer; void updateEqualizer(int value_gain){ bool is_channels_gain_equal=true; for(int index=0; index<10; index++){ esp_err_t result=equalizer_set_gain_info(equalizer, index, value_gain, is_channel...
