Timer1 is used for generating 100 Hz PWM and I want to use INT0 pin with Timer0 to find the duty of a input PWM with frequency from 50Hz to 1KHz.įmax = 1 KHz and So T = 1 ms and so I have used 0.5 ms Timer0 Interrupt. I made the changes and got the 100 Hz PWM working. If you use Timer1, you can only get 100Hz with TOP=OCR1C, output on OC1A, OC1B If you use Timer0, you can only get 100Hz with PWM#7. The Analog Comparator's positive input is Clock source: Register & Counter=no clk. Interrupt on any change on pins PCINT0-5: Off Timer(s)/Counter(s) Interrupt(s) initialization © Copyright 1998-2016 Pavel Haiduc, HP InfoTech s.r.l. This program was created by the CodeWizardAVR V3.28 I need to be able to adjust the PWM duty in the fly.
#Initialization of timer1 in codevisionavr code#
This is the code generated by CodeVisionAVR. I am using Oscilloscope to check the pulses. I generated a code using Timer0 in CodeVisionAVR but I don't see any output on PB0 pin.
How to generate 100 Hz PWM using Timer0 or 1 in ATTiny25 Using CodeVisionAVR ?
