If you've previously installed support for additional hardware configuration, you may already have a "hardware" folder in your sketchbook. Refer to pictures 3 and 4 for the final result Burning Bootloader (if you bought the Bareduino or you are using a bootloaded Atmega328 skip this step) *********IMPORTANT: additional step for Minimal circuit configuration********* 1- Go to and download the Breadboard.zip 2- Create a "hardware" sub-folder in your Arduino sketchbook folder (whose location you can find in the Arduino preferences dialog). ![]() ![]() Now, on your Arduino IDE folder: 1- Create a new folder in "hardware" with the name of leofix 2- Open a text editor and paste this code (picture 2): arduinoispleo.name=Arduino as ISP (Leonardo) munication=serial arduinoispleo.protocol=arduino arduinoispleo.speed=19200 Save the file as programmers.txt (see picture 3) Next we connect some wires to our Leonardo (picture 4): Digital Pin 10,1(TX),0(RX) ICSP MISO,5V,SCK,MOSI,GND (see 6pin pinout on picture 5) Step 3: Target Atmel Microcontroller 1: Atmega328p (materials)įor external 16Mhz crystal and Minimal circuit configuration: 1- Connect the wires from the Leonardo to the atmega328 (please take a look to atmega328 pinouts these are the same with atmega168 -picture 1): Atmega328 Arduino Leonardo (in the picture 1 pins on black) (picture 2- 6pin ICSP) RX pin 2-digital pin 0 TX pin 3-digital pin 1 MISO pin 18-ICSP pin MISO MOSI pin 17-ICSP pin MOSI SCK pin 19-ICSP pin SCK RESET pin1-digital pin 10 And power pins 5v and ground. 1- Open Arduino IDE 2- Open the ArduinoISP sketch (File/Examples/ArduinoISP) 3- Change the following lines (see picture 1): #define RESET SS TO #define RESET 10 #define LED_HB 9 TO #define LED_HB 13 ( we want to use digital pin 10 to reset the target and we are setting the heart beating led on pin 13) 4- Save the sketch as LeonardoISP (so you can use it later) 5- We choose Arduino Leonardo (Tools/Boards/Arduino Leonardo) and the appropriate Serial Port (Tools/Serial Port/COM **) 5- Upload If the sketch was uploaded correctly, you will see the on-board led (the one marked as L) doing a heartbeat sequence. I am assuming that you have already installed and configured the IDE, and you've been able to upload sketches before (If you don't : ). ![]()
