I came here searching for *exactly this*...
I'd removed all the dsi display code from the camera_dsi example and found that the esp_cam_ctlr_receive() hangs when called a second time.

Meanwhile I've had much better results connecting my CSI camera and ESP32-P4 using the esp_video component:

I started this thread a while back, got busy with other things and have only recently looked at it again...

My problem was that my chosen partition scheme did not have an OTA partition!
I chose: Minimal (1.3MB APP / 700KB SPIFFS)
And assumed that with 4MBs of flash memory this scheme would result ...

I may be a bit biased, but I think the OTAWebUpdater example does a better job, particularly that it checks that the firmware uploaded will fit in the OTA partition size.


I have now modified the OTAWebUpdater to work in my sketch but it it fails much like the WebUpdate.
I suspect I'm not ...

I have flashed the WebUpdate example to my WT32-ETH01.
But am confused - how do I create the firmware image file that I will upload?

In Arduino IDE I tried Sketch menu > Export Compiled Binary.
In my sketch folder I see:
/build/esp32.esp32.wt32-eth01/
which contains files:
ConnectBox2.ino.bin ...

I am developing a C application using Eclipse and the ESP-IDF.
I have a WT32-ETH01 dev board with an RFM73 radio transceiver attached, I need help using the RFM73 from my C code.

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

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 ...

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 ...
