If you could build a smart wearable tailored for your own needs, what would you do?
Use the nRF5340 DK with a touch display to show a concept smart wearable. Feel free to integrate any sensors you like such as accelerometer, temperature, GNSS (GPS), etc. Also, show the aggregated data on the display and create some form of graphical user interface (GUI). Transfer data or connect to other devices using Bluetooth LE. Try to push the boundaries of what a smart wearable can do!
watching the Doom gaming with the board [1] sparks met to do this project. instead of Doom, i want something like zwift.
Features
-screen to show game play
-various sensors connection
Technical spec
1MB flash memory for the DK
Development Tool
nRF Connect SDK is Nordic's software development kit for developing both short-range wireless and cellular IoT applications. It supports Zephyr RTOS and Segger embedded studio for free (only for Nordic devices)
It is downloaded from https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Connect-for-desktop as of time of this writing. From there install the toolchain manager and we get the nRF SDK v1.5 as well as the SEGGER Embedded Studio. The installation in described in minutes 34 of [4]. Do note that cmake will fail if we install the toolchain in folder with space. i install it in e:\nordicsemiconductor\ncs
command line build is said to be supported but i couldn't get it working
when plug in the DK and the dongle, be sure to find that they are detected in device manager. For my DK, i got to make the power to be from VDD
Architecture
to use as standalone we need a host
