Okay, it works now 8-) Maybe someone in the future has the same problem, hereby the code: if (EnableSleep){ digitalWrite(POWER, HIGH); //pcb power digitalWrite(26, HIGH); //tcrt led power gpio_hold_en(GPIO_NUM_13); //pcb power gpio_hold_en(GPIO_NUM_26); //tcrt power gpio_deep_sleep_hold_en(); esp_sl...

if (WakkerMaakReden != ESP_SLEEP_WAKEUP_ULP){ init_ulp_program(); } start_ulp_program(); When woken by the push button, you're reinitialising everything related to the ULP while it is still enabled or even active. In my experience, overwriting its program memory while running can cause the ULP to l...

No one that can help me with this?

Hi guys, For a project, I want to wake the ESP32 from deep-sleep when an analog value reaches a specific threshold on the ADC. I also want to wake the main processor when I push a button. Everything works except for one thing: when I wake the main processor with the pushbutton, then the next "round"...

Does anyone here on this forum how I should run this code?

The only thing I want is to read ADC in ULP and if a specific value is reached --> wake up the main processor.

Any help is appreciated


Thanks in advance!

Hi, maybe it will help, I have written it today (works also in Arduino IDE): #include "esp32/ulp.h" #include "soc/rtc_cntl_reg.h" #include "driver/rtc_io.h" #include "driver/adc.h" void ulp_adc_wake_up(unsigned int low_adc_treshold, unsigned int high_adc_treshold) { adc1_config_channel_atten(ADC1_C...
