The maximum input voltage of the ADC0 pin is 0 to 1V if you're using the ESP8266 bare chip. If you're using a development board like the ESP8266 12-E NodeMCU kit, the voltage input range is 0 to 3.3V because these boards contain an internal voltage divider Search within r/esp8266. r/esp8266.

1.1. General Purpose Input/Output Interface (GPIO) ESP8266EX has 17 GPIO pins which can be assigned to various functions by programming the appropriate registers. Each GPIO can be configured with internal pull-up or pull-down, or set to high impedance, and when configured as an input, the data are stored in software registers; the input ca I'm looking to obtain a precise time of arrival of a GPS PPS signal... but I can't find a clean example. I've seen suggestions elsewhere that it may be possible to perform input capture using either the RMT or MCPWM peripherals. Eventually I'd like to capture a sample ready pulse from an ADC, as well. I don't care about pulse duration

This is also called RMT. The name stems from the apparent mapping to an infrared remote control interface where we can supply a signal pattern to RMT and RMT will then own the generation of the signal output with extremely fine grained timings. It also appears to be able to handle incoming signal parsing /***** Sketch to test Input Capture interrupt handling ***** functionality: measure length of pulses on the ICP pin with precision of 0.5 microseconds Show the min and max pulse widths in microseconds on the serial port *****/ #include <stdio.h> // for verbose debugging using sprintf #define icpPin 8 // ICP input pin on arduino #define outPin 2 // output pin that will shadow the input, can be.

Because the input edge capture GPIO pins of timers can withstand a maximum of 5 volt. Moreover, each GPIO pin takes the voltage value between 3.3 to 5 volts as an active high signal and voltage value less than 3 volts as an active low signal. If the voltage amplitude of a digital signal is greater than the logic level of TM4C123 microcontroller, we should first reduce the amplitude using any.
