PWM using timer 0 of ATmega16
Hi, I tried the above suggestions of adding F_CPU before the delay.h header and increased the delay to 250 ms and noticed the same results. However, I noticed 2 very important...

PWM using timer 0 of ATmega16
Quote:Make sure the pwm pin (OCR0) is set to output. I'm doing that already: DDRB |= (1<<PB3);

PWM using timer 0 of ATmega16
Hi guys, I know that with an 8-bit timer you get a lower resolution to drive the servo...but has anybody actually driven a servo using timer0 or timer2 as shown in the code above...

PWM using timer 0 of ATmega16
Although i have used a variable called brightness, I have modified the code originally used to dim an LED, to drive a servo as mentioned by the folks replying to this thread :)...

PWM using timer 0 of ATmega16
Here is the entire program: #include #include #define F_CPU 16000000L //prototypes void InitPWM(void); void SetPWMOutput(uint8_t duty); void Wait(void); int main(void) {...

Quote:??? So are you using the code you posted above, or some other code with 15 and 31 only? This is what I did, if you refer to the code I have pasted in my first post:...

PWM using timer 0 of ATmega16
I tried the code above, but still I see the same issue. The servo moved from left and then it stayed stuck at some position and started twitching continuously. After some time the...

PWM using timer 0 of ATmega16
So that's what I'm doing right? I am varying the servo pulses between 1 ms and 2 ms as seen in the for loop in my above post.

PWM using timer 0 of ATmega16
So based on the above, I changed my code as follows: for(brightness = 15; brightness...

PWM using timer 0 of ATmega16
Hi, Timer resolution = Prescaler/Input frequency = 1024/16 MHz = 64 us Since delay = 1 ms, the timer needs to count 1 ms/64 us = 15.625 timer...
