Hello all
I need to measure a pulse width up to .5 micro second resolution im using the below code
int pin = 7;
unsigned long duration;
void setup() {
Serial.begin(9600);
pinMode(pin, INPUT);
}
void loop() {
duration = pulseIn(pin, HIGH);
Serial.println(duration);
}

I tried using arduino uno, STM32F103C8T6, and Lolin NodeMCU ESP8266 CP2102 all are giving resolution of 1 micro second, and there is an error of +- 2 micro second
i have heard STM32F103C8T6, and Lolin NodeMCU ESP8266 CP2102 are faster than uno.. so it should give much higher accuracy right? but in my case all are same
can anyone help?
