Information

Check that you are using the latest MAXREFDES100HDK firmware for best results. Information on how to update the firmware can be found here:

Getting Started

Connect the HDK to the sensor board

Plug the HDK programming adapter into the health sensor board at the USB type-C connector.

Connect the HDK to a PC

Connect your PC to the HDK board at the micro-USB connector marked HDK. After a few seconds of activity, the PC will recognize the mbed Microcontroller as a standard USB drive.

Press the button on the sensor board

Press and hold the only button on the sensor board for about half a second to wake the PMIC and turn on the board.

Click the MBED.HTM link to get logged in

Go to the new USB Drive, and click MBED.HTM to open it in a web browser. If you do not have an mbed account, choose "Signup", and create your mbed Account. Otherwise, log in with your normal username and password.

This will give you access to the website, tools, libraries and documentation.

PC Configuration

Your mbed Microcontroller can appear on your computer as a serial port. On Mac and Linux, this will happen by default. For Windows, you need to install a driver:

Windows

See Windows-serial-configuration for full details about setting up Windows for serial communication with your mbed Microcontroller. Note this is for the virtual serial port built into the HDK programming adapter

From a host PC to communicate with mbed you will need a terminal application This allows the mbed Microcontroller to print to your PC screen, and for you to send characters back to your mbed.
• Terminals - Using Terminal applications to communicate between the Host PC and the mbed Micrcontroller

Some terminal programs e.g. TeraTerm list the available serial ports by name. However, if you do need to know the identity of the serial port so that you can attach a terminal or an application to it:

Windows

Find the identity of the COM port by opening ''Device Manager''. To do this navigate ''Start -> Control Panel -> System -> Hardware > Device Manager''.

To find the device name under Mac OS X, use the command ''ls /dev/tty.usbmodem*''

Linux

To find the device name under Linux, use the command ''ls /dev/ttyACM*''

Downloading A program

Connect sensor and programming adapter to PC
• Connect the programming adapter to the sensor board as shown below.
• Connect the PC to the programming adapter through the micro USB connector marked "HDK"
• Press and hold the power button for at least a half second to turn the board on.

Save a program binary .bin to the Platform

Download the demonstration program binary:

Note the source code for this program will be seen in the next section.

Save the program binary file to your mbed Microcontroller Disk, just like you would with a normal USB disk. The Status LED will flash as the PC writes the file to the Microcontroller disk. The file is now consumed. Be sure that you turned the sensor board on before saving the file.

Hello World!

The Microcontroller is now running the program flashing LED1 forever! If you reset the Microcontroller, or disconnect and reconnect the power, the program will simply restart.
