In my opinion you should just disable the task watchdog. It's there to ensure that tasks (usually only idleTask) aren't unexpectedly starved. If you know that lower priority tasks will always be starved, by design, then it doesn't make much sense for the watchdog to panic about it. With a big discla...

A: I do this and not worked. how exactly am i supposed to do this? set(EXTRA_COMPONENT_DIRS "${CMAKE_SOURCE_DIR}/components/ui/drv" "${CMAKE_SOURCE_DIR}/components/communication/my_wifi" "${CMAKE_SOURCE_DIR}/components/communication/my_server" ) Remember to do a fullclean. I might be off the mark i...

Try a larger stack size (eg. 4096).

Is anything connected to GPIO 40? Are you using JTAG? Does a different pin number change the behaviour?

I don't know how you get thoose numbers (8uA) , the most conservative approach I can think of is 2ms ON, 13ms OFF permanently, that is 12% of the time ON, so atleast 12uA, just asking Tbh I don't understand what exactly you're trying to measure. Is it between the red dots in your above image? The l...

After research, seems that ULP will need 0.1mA ,if I am not wrong then it is too much energy for my purpose. It will only be >100uA while it's running, but you'd normally only start the ULP periodically (eg. every 20ms) and a typical ULP program has a very short execution time, so the average curre...

I should give up on the idea recording sound on a ESP32 with a power consumption of less than 5mA?

Did you rule out light sleep?

1. Only when the switch is closed.

2. Yes, but it probably doesn't need to be that complicated. Assuming the pin has an internal pullup (ie. <GPIO_NUM_34) then you only need that one pin and no external resistor. The ULP would enable the internal pullup, read pin level, then disable pullup.

I always thought that even 3Mhz should be enough to deal with I2S and sample rates of >44Khz. So you think that the 8Mhz from the ULP is not fast enough the task? Bear in mind that instructions may take up to 12 cycles. Quick back of the napkin math says you can forget about 44kHz. Again, I haven't...
