mbed 介紹

 

前言:

ARM 推出了全面性的物聯網（IoT: Internet of Things）運用平台，該平台包括了 mbed OS 與 mbed 伺服器設備.

keyword:

iot,mbed ,nordic 51422

 

年前,ARM正式推出mbed IDE(整合開發平台) , 其介紹可見what is mbed.

內容有致有

1.MBED MCU

2.MBED compiler

3.MBED SDK

而其中,MBED compiler及SDK都是在線上完成的.

這邊我把手上一個nrf51422 (nordic dongle)為範例操作.

1.去mbed 註冊

https://mbed.org/

2.進入右上方的develop site

3.再進入右上方的compiler

4.select device

5.new a project(select device)

 

6.new a file(main) and lib(mbed)

(Click the right button on the mouse at the project name,example "blink"))

 

(the file must *.cpp),it use the c++

7.program (you should reference the mbed lib (or other lib))

select the mbed lib and export it to click the DigitalOut

write follow in main.cpp

#include "mbed.h"

DigitalOut led(LED1);

int main()

{

    while(1){

        wait(1);

        led=!led;

        }

}

 

8.compiler and download

(the loader ,the brower will download the bin file)

9.loader (by your develop board,put the into loader mode)

10.reboot your device ,should be work.

MBED 的用途

MBED 是专为实验及反覆操作而设计的，主要是测验某种东西或方法而不是优化解决方案。因此，它适合专业嵌入式工程师，也适合想初次尝试的门外汉

”

最後,這讓我感覺這個像是另一個"arduino". 然而這個應是現階段的部份.

而在之後在在mbed OS出來後.一定會變成下一個arduino.(只是在只是AVR平台而已)

而且也可以跟著不同板子有不同的功能.如nrf5144有radio(ble 'ant and proprotal)
