Re: Wake Up - ADC - Hall Sensor

Hi! Dear Brandobur! I tried this example in Arduino. in setup () I call ulp_adc_wake_up (unsigned int low_adc_treshold, unsigned int high_adc_treshold) with different parameters, but it always wakes up the processor without a magnet. The arduino hallread() return integer value, i look 80-100 without...

Re: ESP32 + LAN8720 (Connection failed)

I can't help you.
You do not provide any information.
No schematic, no program....
what it means "loading Google", what is/where is "google", is it your browser, website or whatever ?????
you need to be able to ask :)

Re: ESP32 + LAN8720 (Connection failed)

Whats modules used? How to wired/modificated?
try eth_addr 1

Re: Why are GPIOs 34 and 35 always LOW ?

You are in write mode only. gpio34/35 INPUT only (without pullup) if you need to check the pin state use the pinMode(GPIO, INPUT); xxx= digitalRead (GPIO); if you need to check the pin status, use ------- digitalWrite(..) can only be used for output pins , then you can set the output voltage level t...

Re: Why are GPIOs 34 and 35 always LOW ?

pinMode(GPIO, OUTPUT); digitalWrite(GPIO, STATE); --- pinMode(GPIO, INPUT); or INPUT_PULLUP INPUT_PULLDOWN xxx=digitalRead(GPIO); --- If the pin is configured as an INPUT, digitalWrite() will enable (HIGH) or disable (LOW) the internal pullup on the input pin. It is recommended to set the pinMode() ...

Re: Why are GPIOs 34 and 35 always LOW ?

Input only pins GPIOs 34 to 39 are GPIs – input only pins. These pins don’t have internal pull-ups or pull-down resistors. They can’t be used as outputs, so use these pins only as inputs: GPIO 34 GPIO 35 GPIO 36 GPIO 39 https://randomnerdtutorials.com/esp32-pinout-reference-gpios/ use external pullu...

Re: ESP32-SD CARD

Hardware schematic?
what is VSEL ? https://randomnerdtutorials.com/esp32-p ... nce-gpios/
why not use gpio2 for SDCARD CS and GPIO5 for DAC CS?
