Get Started‚Äč

enter image description here

  1. Click this link to login or signup to mbed
  2. Import the mbed_blinky program
  3. Coding! Then you can compile the code and download the output binary.
  4. Now connect your Arch board to your pc and long press the reset button, it will automatically appear as a USB driver named CRP DISABLD. Go to the CRP DISABLD, delete the firmware file and copy the download binary file to CRP DISABLD. Quick press the reset button to run the new binary.

You can change the code as following and try again.

    #include "mbed.h"

BusOut leds(LED1, LED2, LED3, LED4);

int main() {
uint8_t count = 0;
while(1) {
leds = count++;
wait(1);
}
}

Programming Arch on Windows, Linux or Mac‚Äč

Arch does not have an mbed interface. It uses USB In-System-Programming(ISP) to upgrade the firmware.

To enter the USB ISP mode, connect the Arch with your computer and long press its button, and then a disk named "CRP DISABLD" will appear.

  • On Windows

    1. delete firmware.bin in the "CRP DISABLD" disk.
    2. copy a new firmware into the disk.
  • On Linux

    1. if the disk is not mounted, mount the disk at {mnt_dir}
    2. dd if={new_firmware.bin} of={mnt_dir}/firmware.bin conv=notrunc
  • On Mac you will need to use Terminal to run the following script to copy you're .bin file to your Arch

    1. dd if={new_firmare.bin} of=/Volumes/CRP\ DISABLD/firmware.bin conv=notrunc

If you are so inclined, you can also create an Automator application to support drag-and-drop of the file to your board. Just create a "Run Shell Script" with the following command:

dd if=$* of=/Volumes/CRP\ DISABLD/firmware.bin conv=notrunc

You will also need to change the "Pass Input" option from "to stdin" to "as arguments"--without this you will get an error "The action 'Run Shell Script' encountered an error" or "dd: no value specified for if (1)" in the log.

Also, an improved form of the script is:

dd if="${1}" of=/Volumes/CRP\ DISABLD/firmware.bin conv=notrunc

Which should handle spaces in the file path and only uses the first file supplied.

Quick press the button to run the new firmware.
