Overview¶

Hexiwear has been designed by MikroElektronika in collaboration with NXP to improve support developer projects past accelerating their time to market place, reducing their evolution and manufacturing costs and securing their migration from epitome to production. For only $49, this open-source reference-design for IoT/connected applications brings together everything developers need to blueprint their next IoT application in a very compact form cistron (2" 10 two").

Featuring more than than traditional MCU development platforms, the Hexiwear platform is ideal for connected applications, thanks to its power-efficient Kinetis K64F MCU featuring:

  • ARM® Cortex®-M4 cadre;
  • max frequency up to 120MHz;
  • 1024KB Flash, 256KB RAM;
  • many peripherals (16-flake ADCs, DAC, Timers);
  • interfaces (USB Device Crystal-less, UART, SPI, I2C, I2S, SD-card).

Integration is as well a key feature of Hexiwear, with a Bluetooth Low Energy (BLE) SoC (Kinetis KW40z) and eight Sensors onboard:

  • 6-centrality Accelerometer and Magnetometer combo (FXOS8700CQ);
  • 3-centrality Gyroscope (FXAS21002CQ);
  • Pressure sensor accurate upward to Distance sensing (MPL3115A2);
  • Temperature and humidity philharmonic (HTU21D);
  • Ambience light sensor (TSL2561);
  • Optical Heart rate sensor (Maxim MAX30101).

Information technology also includes a 1.1" OLED color display and a 190mAh 2C Li-Po battery with a charger (MC34671) (encounter cake diagram below).

The Kinetis K64 MCU family remains fully software, hardware and evolution tool compatible with Kinetis MCUs, and existing NXP Freedom projects (using the FRDM-K64F Freedom platform) can be easily migrated to Hexiwear.

The docking station for Hexiwear allows developers to hands programme and debug their code (built-in USB Debug and Flash Programmer) and expand the board features with up to three click boards™ among a portfolio of more than than 200 references.

PC Configuration¶

The Docking station embeds (on the back) a controller, which emulates the latest ARM DAP-LINK debug interface, featuring MSD Flash programming, Debug and virtual Series Series port. You must connect your computer via the USB cable to the micro-USB port of the Docking station. Make sure that the PWR switch of the Docking station is set ON and the green PWR condition light volition come up on, indicating it has ability. The MSD bulldoze and the Debugger are automatically detected yet the Virtual Series port must be properly setup for your figurer. On Mac and Linux, this will happen by default. For Windows, yous demand to install a driver:

From a host PC to communicate with mbed you will need a terminal application. This allows Hexiwear via the micro-USB port of the Docking station to print to your PC screen, and for you to send characters back to your mbed.

  • Terminals - Using Concluding applications to communicate between the Host PC and the Hexiwear via the micro-USB port of the Docking station.

Some last programs (e.g. TeraTerm) list the available series ports by proper name. Nonetheless, if you do need to know the identity of the serial port so that y'all can attach a final or an application to it:

Windows Mac Linux
Detect the identity of the COM port by opening ''Device Manager''. To do this navigate ''First -> Command Panel -> System -> Hardware -> Device Director''. To find the device proper noun under Mac Os X, utilise the command ''ls /dev/tty.usbmodem*'' To find the device name under Linux, use the control ''ls /dev/ttyACM*''
windows mac linux

Get Started with mbed¶

one. First lath connection¶

Plug Hexiwear on the Docking station and connect the one stop of the USB cablevision to your computer and the other end to the micro-USB port of the Docking station. Make sure that the PWR switch of the Docking station is prepare ON and the green PWR status low-cal will come on, indicating it has power. Afterward a few seconds of activity, the PC will recognize the mbed Microcontroller equally a standard USB drive called "DAP-LINK".

two. Connect to mbed¶

Go to the new USB Bulldoze, and click MBED.HTM to open it in a web browser.

If you do not have an mbed account, cull "Signup", and create your mbed Account. Otherwise, log in with your established mbed username and password.

This will give y'all access to the website, tools, libraries and documentation.

3. Download a (.bin) to Hexiwear¶

Save the program binary file to the DAP-LINK drive from your file explorer, simply similar you would with a normal USB disk. The Status LED will flash as the PC writes the file to the Microcontroller disk.

4. Printing the Reset Push button¶

When the Reset_K64F Button located on the Docking station is pressed, the newest plan on the DAP-LINK drive will exist loaded in to the K64F microcontroller FLASH memory. The Condition LED volition flash every bit this happens. When the program has been loaded onto the K64F microcontroller, it will then kickoff it running.

5. Run the Program¶

The K64F microcontroller is at present running the plan; flashing LED1/Carmine located on Hexiwear forepart console forever! If you reset the K64F microcontroller, or disconnect and reconnect the power, the program volition merely restart.
