ATMEGA328P external interrupt avr gcc won't happen. An external interrupt vector should occur when a 5v input is supplied to int0. The interrupt should change a volatile integer flag to allow a LED to illuminate that is connected to a pin on PORTB. I think if using mode 1, you'd either have to use an external clock source (TOSC1 pin when AS2 = 1) or have to change the clock scale factor of the processor to effect the PWM rate. Not positive though since I've never used the ATmega1284, but from skimming the data sheet that's what it looks like to me.

Timer/Counter2 is capable of running on 4 modes the Fast PWM with a max TOP (0xFF), a Fast PWM mode with a variable TOP (OCR2A), a Phase Corrected PWM mode with a max TOP (0xFF) and a Phase Corrected PWM mode with a variable TOP (OCR2A).

Fast PWM. The ATmega328 has 3 counters and usually runs at 16MHz. We will focus on counters #0 and #2 —counter #1 is a bit different. A PWM waveform is generated from a counter by counting clock ticks, a register and a comparator. The counter's purpose is to create the duty cycle resolution. One complete cycle of the counter is one period of your PWM.

I had read that not all the pwm pins had the same frequency but couldn’t find a list on the Arduino website with the different frequencies of the pwm pins. So I used my oscilloscope to check the frequencies of the different pwm pins.
Mar 06, 2013 · This video show a platform for controlling DC Motor speed and direction with AVR Atmega (speed is not controlled here, it is always set to 100%). The timer/counters are set to phase-correct 8-bit PWM mode and with clock prescaled to system clock divided by 64. However timer0 is set to fast PWM mode for use with the millis()/micros() code. For standard Arduinos the system clock is 16MHz so that the timers are clocking at 250kHz by default.
I think if using mode 1, you'd either have to use an external clock source (TOSC1 pin when AS2 = 1) or have to change the clock scale factor of the processor to effect the PWM rate. Not positive though since I've never used the ATmega1284, but from skimming the data sheet that's what it looks like to me.

Sooner or later, the Arduino starts to feel a little claustrophobic. Your sketches start running out of memory, so you need more RAM. You want to talk serial to another peripheral (like an RFID Module) AND watch the action in the Serial Monitor at the same time, so you need more UARTS.

This ATmega1284-based project can convert the color to sound directly. It can be used as cassette player that plays through a tape of colors. It determines the RGB content of a surface and then speaks the color or plays a musical tone at the sound frequency mapped to the color. ATMega328P PCINT example.

White = PWM input Servo control is done by sending a pulse width modulationor PWM signal to the PWM input pin. The servo compares that signal to the actual position of the servo and adjusts the servo accordingly. The internal circuitry of the servo expects a constant 50Hz PWM signal (a 50 Hz signal is one that repeats every 20 ms). 1/50 Hz = 20 ms The timer/counters are set to phase-correct 8-bit PWM mode and with clock prescaled to system clock divided by 64. However timer0 is set to fast PWM mode for use with the millis()/micros() code. For standard Arduinos the system clock is 16MHz so that the timers are clocking at 250kHz by default. I'm having a hard time to set a 16 bit PWM on atmega328 that works with frequency of 50Hz and have a duty cycle that can be varied. I also have my doubts that if I can have an ADC working together with this 16 bit PWM since both use timer1. I am trying to control LEDs brightness using PWM on the Atmega32. I have one LED connected to each of the 4 PWM pins (OC0, OC1A, OC1B, and OC2). Using the code below, all of the LEDs are functioning as expected except the LED connected to OC1A which is remaining dark.
