ADC clock division in RTC mode

Hi, in ADC RTC mode, is it possible to change the ADC speed using adc_set_clk_div() function? My code: #include <stdio.h> #include <stdlib.h> #include <math.h> #include "freertos/FreeRTOS.h" #include "freertos/task.h" #include "driver/gpio.h" #include "driver/adc.h" #include "driver/timer.h" #includ...

Re: LilyGo-T-Call-SIM800L - How to detect power source USB-C or BATTERY

hi, - does your development board have access to the 5V, 3.3V, and GPIO pins for example on a pin header? the battery voltage may also be available as VBAT? - to detect battery voltages using a GPIO pin, in hardware configuration first drop the voltage down through a resistive voltage divider (examp...
