However, this isn't the only option for using Arduino to upload code to the microcontroller. In our first example, we used the Arduino to upload code to the ATmega328P. Google Code Archive - Long-term storage for Google Code Project Hosting.After that we configure the Timer0 in normal mode with pre-scalar of 8 by setting appropriate bits in the TCCR0A and TCCR0B registers. Then we have load 206 count value into the TCNT0 register. In this Atmega328p Timer interrupt example program code, we have configured the Port B Pin 0 an output.For other tutorials on PWM see the followings: Generate Sine Wave using Arduino PWM and Simulink

In the next tutorial we will show how to use the Phase Correct PWM with ATmega328P. So in this tutorial on generating PWM signals using timers in the atmega328p chip, we have illustrated the Fast PWM mode with example code.ESP MISO -> ATmega328P MISO ESP MOSI -> ATmega328P MOSI ESP SCK -> ATmega328P SCK What I did so far is the following: Uploaded the "Examples > ArduinoISP > ArduinoISP" sketch using the Arduino IDE to the ESP-12S Made the following connection between the ESP-12S and the ATmega328P. ATmega328P (using an Arduino NANO clone) Arduino IDE.eeprom main main.hex $ avrdude -F -V -c arduino -p ATMEGA328P -P /dev/ttyACM0 -b 115200 -U flash:w:main.hex avrdude: AVR device initialized and ready to.
