用arduino mega2560通过isp给 arduino uno烧录程序

用arduino mega2560通过isp给 arduino uno烧录程序

一直想通过最基本的方式来烧录arduino程序，没有bootloader，不使用arduino IDE，基于avr-libc库来写程序，再用avrdude来烧录。

  • 由于手上有两块arduino板，一块uno，一块mega2560。就想着用mega来做isp工具，来给uno烧录程序，就有了以下过程

  • mega做成isp烧录工具

    1. 在arduino IDE里写入isp程序：

    2. 首先选择工具档： Tools > Board > mega2560

    3. 再选择 File > Example > ArduinoISP

    4. 编译上传

  • 连接meag和uno

    1. 参考这篇文章

      Arduino as ISP and Arduino Bootloaders | Arduino Documentation

    2. 具体是这张图：

    3. 描述如下：

      The Arduino MEGA above is programming an Arduino UNO connecting D51-D11, D50-D12, D52-D13, GND-GND, 5V-5V and D10 to RESET. This type of board needs a 10µF electrolytic capacitor connected to RESET and GND with the positive (long leg) connected to RESET. The capacitor has to be placed after the programmer board has been loaded with the ISP sketch.

      The 10µF electrolytic capacitor connected to RESET and GND of the programming board is needed only for the boards that have an interface between the microcontroller and the computer's USB, like Mega, UNO, Mini, Nano. Boards like Leonardo, Esplora and Micro, with the USB directly managed by the microcontroller, don't need the capacitor.

      注意：reset引脚上要接一 个电容

  • 通过arduino IDE确认烧录命令

    1. 打开一个想烧录的例子程序，比如 Blink
    2. 选择目标板（uno）：Tools > Board > Arduino Uno
    3. 选择工具板 （mega2560）：Tools > Port > 选择mega2560 （来作为"Arduino as ISP"）
    4. 选择 Tools > Programmer > Arduino as ISP
    5. 注意，选择 Sketch > Upload Using Programmer ；而不是点工具栏的 编译。
    6. 第5步之后，就会通过isp方式，擦除uno的flash，并烧录blink的程序。可以在arduino IDE后台的log里找到刚刚执行的烧录的命令：

      • 我的系统是arch linux，我的用户目录为 /home/suah，截取的log的第一行就是烧录的命令，后续我们自己修改目标文件，就可以随时烧录自己的程序了

  • 写个程序，手动编译，烧录

    • 程序 main.c

      #include <avr/io.h>
#include <util/delay.h>void Led_Config();
void Led_On();
void Led_Off();void main()
{Led_Config();while(1) {Led_On();_delay_ms(500);Led_Off();_delay_ms(500);}
}void Led_Config()
{DDRB |= (1 << 5);
}void Led_On()
{PORTB |= (1 << 5);
}void Led_Off()
{PORTB &= ~(1 << 5);
}

    • Makefile(注意修改 烧录时的变量 AVRDUDE，使其与上一大步确认过的烧录命令一样)

      # parameters (change this stuff accordingly)
# project name
PRJ = main
# avr mcu
MCU = atmega328p

    • 把makefile和main.c放在同一目录下，先 执行make ，再make flash 直接烧录，如下log：（注意，提前安装好所需的工具链，如 ：make，avr-gcc等 ）
