Blink a LED

Dependencies:   mbed

Seeed_Arch_link_Blinky

Setup

1. Connect the Temperature sensor as well as the Servo to the Seeeduino-Arch-Link board, and then connect the board to you PC using the micro-USB cable.
2. The board mounts as a mass-storage device (like a USB drive). Verify that you can see it (drive name will be MBED).
3. Go to http://developer.mbed.org
4. Create an ARM mbed account if you do not have one.
5. On the top right corner, click the Compiler button.

An IDE should open. Congratulations!

On Windows: To see debug messages, install the serial driver.

Debug messages: We can talk to the board via a serial port, but you might need some software. Read this doc and install required software (like PuTTY or CoolTermon Windows).

Locally: If you like things locally, you can do so by exporting to a supported toolchain.

I very much recommend to just use the online IDE, as it makes it easier for us, but if you want to continue hacking in the future, this is a nice way.

Seeed_Arch_link_Blinky

1. First we need to set up our project and our target. In a new browser window, open https://developer.mbed.org/platforms/Seeed-Arch-Link and click the Add to your mbed Compiler button.
2. Go back to the compiler browser window and click F5 to refresh the page.
3. Click the Import button, then click "Click Here to import from URL"
4. Paste the URL https://developer.mbed.org/teams/znrobotics/code/Seeed_Arch_link_Blinky/
5. Double click to open main.cpp
6. Try to finish the code under ' YOUR CODE HERE : turn on the LED'

1. Now press Compile
2. A file downloads (Seeed_Arch_link_Blinky_ARCH_LINK.hex)
3. Drag the file to the 'MBED' disk
4. The LED on the board will flash.
5. After flashing, hit the 'Reset' button to start the program.
6. Seeed_Arch_link_Blinky runs!
