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, on board 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.

Features

Please go to our MAXREFDES100HDK wiki page for details on how to load the latest firmware.



Getting Started with MAX32630FTHR

1. Connect the MAX32630FTHR to the MAXREFDES100HDK

Use the fine pitch 10pin 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 recognise the mbed Microcontroller as a standard USB drive.

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 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

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.

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:

WindowsMacLinux
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 "Hello World!" 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.

2. Press the Reset Button

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

3. 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.

Import programmbed-os-example-ble-HeartRate

This application transmits a heart rate value using the Bluetooth SIG Heart Rate Profile. The heart rate value is provided by the application itself, not by a sensor, so that you don't have to get a sensor just to run the example. The canonical source for this example lives at https://github.com/ARMmbed/mbed-os-example-ble/tree/master/BLE_HeartRate

BLE Support in mbed OS

Make sure you are using mbed OS 5.5.5 or later for BLE support on the MAX32630FTHR platform.

Technical Reference

Power

Power/Reset Button

The button located next to the battery connector acts as both a reset button and power button. When the board is on, pressing the button will drive reset signal going to the MAX32630 and the header pin low.

The board will turn on automatically any time power is applied to the micro USB connector. If a only a battery is connected, you can turn on the board by a half second press to the power/reset button. When the board is on, a 12 second long press will turn the board off. If the long press is applied when operating from battery power, the board will remain off. If USB power is available during the long press, the board will turn off for 1 second and then turn back on.

Note that the header pin labeled PWR is connected in parallel with the power/reset button and pulling this header pin to ground will have the same effect as pressing the button. The header pin labeled RST is the reset signal. Pulling RST to ground will reset the MAX32630, but it cannot turn the board on or off.

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.
