Introduction

This explains how to use an Arduino as a programmer to program the microcontroller selected for our project, the ATtiny2313.

Preparing Arduino to be used as a programmer

Upload this to the Arduino (Uno, Dueminalove) from Arduino IDE:

https://raw.github.com/adafruit/ArduinoISP/master/ArduinoISP2.pde

IMPORTANT:

(see attachment .zip for the folder)

• Save file into a folder called ArduinoISP2
• Open the project ArduinoISP2.pde in Arduino IDE
• Select the Tools > Board = Arduino Uno (or Dueminalove)
• Select the Tools > Serial port of your Arduino Uno (or Dueminalove)
• Upload

Connecting the Arduino to the ATTINY2313

Insert the 10uF capacitor between Arduino RESET and GND pin (longer pin in RESET).

Connect the Arduino to the ATtiny2313:

Arduino   Attiny2313

13        19 PB7/SCK
12        18 PB6/MISO
11        17 PB5/MOSI
10        1 PA2/Reset
5v        20 VCC
GND       10 GND

Uploading a program to the ATtiny2313

• In Arduino IDE, change the configuration to ATtiny2313.
  • Tools > Board: ATtiny2313, 8Mhz
  • Tools > Port: your serial port
  • Tools > Programmer: Arduino as ISP
• Open the blink sample.
• Change PIN from 13 to 0
• Upload
