ATmega328p Examples

This project aims to provide examples for using the peripherals of the ATmega328p

Everything is thorougly commented to provide traceability for all users

You can use the examples as a foundation for your own projects

Included Peripherals:

• UART
• Twin Wire Interface (TWI / I2C)
• GPIO + external interrupts
• 8 and 16 bit timers, with interrupts
• Pulse-Width Modulation (PWM)

Future Additions:

• ADC
• SPI

Once I get around to it...

References

Refer to the header files of the source code for documentation and use the ATmega328p datasheet to follow along. You can find all the code in demo/.

Usage

---

Uses the Arduino Uno as a hardware platform, without the Arduino IDE. Coded and tested everything under Linux.

NOTE:

Depending on which demos you want to try, you may need some additional hardware (for example a MPU6050 sensor for the TWI demo).

---

To use the examples in this project under Linux install the arduino package, it provides all necessary tools. You also might also need to install the C Development Tools for your distro. You can compile the code using the provided Makefiles and use the flash_script.sh to flash the code to the arduino.

Example:

* cd demo/external_interrupt
* make -> yields ext_int_test
* ./flash_script
* enter "ext_int_test"
* code should now run on the hardware
