Maximum Frequency of a ESP8266 – Revisited
The ESP8266 can yield a 163 kHZ wave using the Arduino IDE and writing the code in C. The code used is: int pin = 5; void setup() { pinMode(pin, OUTPUT);
Read MoreMaximum Frequency an ESP8266 can yield
An ESP8266 running NodeMCU can yield maximum frequency of 1.44 kHz with a duty cycle of 61%. The wave form is given below. The code used to perform this test is: pin =
