MAX32630FTHR

MAX32630 Rapid Development Platform

Overview¶

The MAX32630FTHR board is a rapid development platform designed to help engineers quickly implement battery optimized solutions with the MAX32630 ARM Cortex-M4F microcontroller. The board also includes the MAX14690N Wearable PMIC to provide optimal power conversion and battery management. The form factor is a small 0.9” by 2.0” dual row header footprint that is compatible with breadboards and off-the-shelf peripheral expansion boards. Additionally, onboard are a variety of peripherals including a dual mode Bluetooth module, micro SD card connector, 6-axis accelerometer/gyro, RGB indicator LED, and pushbutton. This provides a power-optimized flexible platform for quick proof-of-concepts and early software development to enhance time to market.

This pinout and form-factor for this board are based on the Adafruit feather series of boards and it is intended to be compatible with many of their peripheral wings, but it is not guaranteed to work with all FeatherWings.

A MAX32630FTHR APPS wiki page is available with more hints and examples.

Firmware¶

Getting Started with MAX32630FTHR¶

1. Connect the MAX32630FTHR to the MAXREFDES100HDK¶

Use the fine pitch 10-pin ribbon cable to connect the boards from the SWD (J3) header on the HDK to J4 on the MAX32630FTHR.

2. Connect the MAX32630FTHR to a power source¶

Use a micro USB cable to connect the MAX32630FTHR board to a suitable power source (no USB connectivity is required). Alternatively, you can power the board from a charged battery as long as you remember to turn it on by pressing the power/reset button next to the battery connector. The board turns on automatically when powered from the USB supply.

3. Connect the MAXREFDES100HDK to a PC¶

Use a micro USB cable to connect the HDK to a PC, through the connector marked HDK. The status light will come on, indicating it has power. After a few seconds of activity, the PC will recognize the mbed Microcontroller as a standard USB drive.

Windows XP example	Mac OS X example

4. 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. This will take you to the MAX32630FTHR platform page. If you end up at a different page, go to our MAXREFDES100HDK wiki page for details on how to load the latest firmware.

If you do not have a mbed account, choose "Signup", and create your mbed Account. Otherwise, login with your mbed 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:

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 Microcontroller

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

Downloading A program¶

1. Save a program binary (.bin) to the Platform¶

Download the appropriate "Blinky" binary:

• MAX32630FTHR: blinky_max32630fthr.bin

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.

2. Press the Reset Button¶

When the Reset Button is pressed, the microcontroller will be reset and the last programmed application will begin to run.

3. Blinky¶

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.

Technical Reference¶

Power¶

• USB or Battery Powered
• 5.0v from USB available on VBUS (when USB is connected)
• SYS supply automatically switches between battery voltage and VBUS when available
• 1.8V regulated output
• Programmable LDO (typically 3.3V)
• Digital IO pins are individually programmable to 1.8V or 3.3V

Battery Charger¶

The MAX14690 includes a battery charger suitable for Lithium Ion and Lithium Polymer batteries. The charge current is set by a resistor attached to the SET pin on the MAX14690. The 20K Ohm resistor installed by default sets the charge current at 100mA which is tolerable for most typical batteries with a capacity greater than or equal to 100mAhr. The default charge voltage is 4.2V, but this is programmable by I2C. Please consult the MAX14690 datasheet and the datasheet for your battery to ensure compatibility.
