Questions about ULP in deep sleep

I have few questions about using ULP in deep sleep.
1. Is there option to read RTC clock in ULP code
2. I am looking for ULP I2C example, but not the bitbanging, but using I2C_Read and I2C_Write assembler commands (not very important).

Thanks in advance.

Maybee you can say to me wheater it is right that I need the cmakelists.txt & component.mk? CMakeLists.txt is required ...

Re: ESP32-CAM Problem with not enough pins

https://github.com/espressif/esptool/wiki/ESP32-Boot-Mode-Selection When you read this you can see that pin 12 cant be connected to VCC (in your case, from your issue description): If driven High, flash voltage (VDD_SDIO) is 1.8V not default 3.3V. Has internal pull-down, so unconnected = Low = 3.3V....

Re: Disabling & Re-enabling BLE

Maybe this is not about esp-idf structure, but recently I found this video on yt. On this screenshot you can see how controller is separated from host:

Re: analog sensor value to web server school project need help please!

Where is the school that 8 yo kids are building such complicated projects? Try to move this code from handle_OnConnect to loop: float temp = dht.readTemperature(true); float humid = dht.readHumidity(); soilVal = analogRead(soilSensor); int soil = map(soilVal, 3350, 1500, 0, 100); //soil = constrain(...
