Re: get timestamp in milliseconds
Thanks kolban, The problem is xTaskGetTickCount and getTimeSinceStart will return the time passed since the device was turned on, but I'm looking for the date time output. I think it's possible to make something with time and getTimeSinceStart but I suppose I'll lose some precision, if there is not ...

Re: ESP-WROOM-32 with USB TTL
The problem seems to be solved adding a 100uf capacitor between the 3V3 and GND

ESP-WROOM-32 with USB TTL
Hi, I need a little help. I'm connecting the ESP-WROOM-32 module with a USB to TTL dongle (based in CP2102 chip) The idea is to make a PCB with necessary components to connect 4 only wires between the PCB and the USB TTL, at this moment I have this wiring: TTL ____ WROOM-32 3V3 ------- 3V3 GND -----...

Re: Change level wake after first wake up
sorry if what I'm doing is nonsense You're forgiven :P Hahaha Thanks after re-think about my problem I concluded that my approach was wrong, I was making a mountain out of a molehill. So I solved first, storing the wake up level in the RTC memory. I've assigned the value of -1 to know if the device...

Re: Change level wake after first wake up
As I'm new with ESP, there some things I'm not familiar with, so as I understand now: #define PULSE_CNT_IS_HIGH() \ ((REG_GET_FIELD(RTC_GPIO_IN_REG, RTC_GPIO_IN_NEXT) \ & BIT(GPIO_NUM_33)) == 1) PULSE_CNT_IS_HIGH (I've renamed) will check if the pin is still in high, which make the device wakes up. ...

Re: Change level wake after first wake up
Thank you both for your answers I've tried with: static void RTC_IRAM_ATTR wake_stub() { ets_printf(alive_prnt); SET_PERI_REG_BITS(RTC_CNTL_EXT_WAKEUP_CONF_REG, 0x1, 1, RTC_CNTL_EXT_WAKEUP0_LV_S); } the ets_printf is to know the function is executed. But it keeps having the same behavior, the esp go...

[SOLVED] Change level wake after first wake up
I'm doing this to sleep my device: esp_deep_sleep_enable_ext0_wakeup (GPIO_NUM_33, 0); As my external pulse will remain LOW for a long time, I'd like to change the trigger level to the oposite. I understand this can be done with a stub, but I'm not sure if it's really possible. Is it possible, can a...
