Este tutorial explica cómo usar una placa Arduino como un AVR ISP (In System Prgrammer). Esto te permite usar la placa para programar el bootloader a Microcontroladores AVR (por ejemplo los ATmega168 o ATmega328 usados en Arduino). El programa de este ejemplo está basado en el firmware mega-isp de Randall Bohn. Este ejemplo requiere la versión Arduino 0018.

1. Conecta los cables desde tu placa Arduino a la placa que quieres programar como se muestra en el diagrama de abajo.

Instrucciones

Para usar tu placa Arduino para progamar el bootloader a un microcontrolador AVR tienes que seguir estos simples pasos.

1. Carga el programa ArduinoISP (en Ejemplos) a tu placa Arduino
2. Conecta los cables desde tu placa Arduino a la placa de entrenamiento como se muestra en el diagrama de abajo.
3. Selecciona en el menú Tools > Board la placa a la que corresponda el chip al que quieres programar el bootloader (no la placa que estás usando como programador). Para más detalles mira las descripciones de las placas en environment page.
4. Usa el comando Burn Bootloader > Arduino as AVRISP.

Circuito

Una placa Arduino actuando como un ISP para programar el ATmega a otra placa Arduino. Ten en cuenta que necsitas acceder al pin de reset de la placa, el cual no está disponible en NG o placas más antiguas.

En placas NG o más antiguas, conecta el cable de reset al pin 1 del ATmega en la placa, como se muestra arriba

On NG or older boards, connect the reset wire to pin 1 of the Atmega chip on the board, as shown above.

1. Select the item in the Tools > Board menu that corresponds to the board on which you want to burn the bootloader (not the board that you're using as the programmer). See the board descriptions on the environment page for details.

This tutorial explains how to use an Arduino board as an AVR ISP (in-system programmer). This allows you to use the board to burn the bootloader onto an AVR (e.g. the ATmega168 or ATmega328 used in Arduino). The code in this example is based on the mega-isp firmware by Randall Bohn. This example requires the forthcoming Arduino 0018.

This tutorial explains how to use an Arduino board as an AVR ISP (in-system programmer). This allows you to use the board to burn the bootloader onto an AVR (e.g. the ATmega168 or ATmega328 used in Arduino). You can also use this technique to bypass the bootloader and program the microcontrollers directly. The code in this example is based on the mega-isp firmware by Randall Bohn.

To use your Arduino board to burn a bootloader onto an AVR, you need to follow a few simple steps.

1. Upload the ArduinoISP firmware (in Examples) to your Arduino board.

1. Select the item in the Tools > Board menu that corresponds to the board on which you want to burn the bootloader (not the board that you're using as the programmer).
2. Use the Burn Bootloader > Arduino as AVRISP command.

Using an Arduino as an AVR ISP (In-System Programmer)

This tutorial explains how to use an Arduino board as an AVR ISP (in-system programmer). This allows you to use the board to burn the bootloader onto an AVR (e.g. the ATmega168 or ATmega328 used in Arduino). You can also use this technique to bypass the bootloader and program the microcontrollers directly.

Instructions

To use your Arduino board to burn a bootloader onto an AVR, you need to follow a few simple steps:

1. Load the avrisp firmware (below) onto your Arduino board as you would any other sketch.
2. Wire your Arduino board to the target as shown in the diagram below.
3. Select the appropriate item from the Tools > Board menu.
4. Use the Burn Bootloader > Arduino as AVRISP command.
