merhaba arkadaşlar ben pwm ile 10 khz sinyal oluşturdum fakat sinyal 1 ve 0 arasında garip bir şekilde gidip geliyor. ben 10 khz süresince yani 100us de 1 kez 1 ve 0'a gitmesini istiyorum. kodlar burda bunu değiştirip bana gönderirseniz çok sevinirim.
#include <PWM.h>
//use pin 11 on the Mega instead, otherwise there is a frequency cap at 31 Hz
int led = 7; // the pin that the LED is attached to
int brightness = 0; // how bright the LED is
int fadeAmount = 5; // how many points to fade the LED by
int32_t frequency = 20000; //frequency (in Hz)
void setup()
{
//initialize all timers except for 0, to save time keeping functions
InitTimersSafe();
//sets the frequency for the specified pin
bool success = SetPinFrequencySafe(led, frequency);
//if the pin frequency was set successfully, pin 13 turn on
if(success) {
pinMode(13, OUTPUT);
digitalWrite(13, HIGH);
}
}
void loop()
{
//use this functions instead of analogWrite on 'initialized' pins
pwmWrite(led, brightness);
brightness = brightness + fadeAmount;
if (brightness == 0 || brightness == 255) {
fadeAmount = -fadeAmount ;
}
delay(30);
}
