MAX32620HSP (MAXREFDES100) RPC Example for Graphical User Interface
Dependencies: USBDevice
Fork of
HSP_Release
by 
Jerry Bradshaw
This is an example program for the MAX32620HSP (MAXREFDES100 Health Sensor Platform). It demonstrates all the features of the platform and works with a companion graphical user interface (GUI) to help evaluate/configure/monitor the board. Go to the MAXREFDES100 product page and click on "design resources" to download the companion software. The GUI connects to the board through an RPC interface on a virtual serial port over the USB interface.
The RPC interface provides access to all the features of the board and is available to interface with other development environments such Matlab. This firmware provides realtime data streaming through the RPC interface over USB, and also provides the ability to log the data to flash for untethered battery operation. The data logging settings are configured through the GUI, and the GUI also provides the interface to download logged data.
Details on the RPC interface can be found here: HSP RPC Interface Documentation
Windows
With this program loaded, the MAX32620HSP will 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: HSP serial port windows driver
For more details about this platform and how to use it, see the MAXREFDES100 product page.

Removed Bulk Erasing, instead a small number of bytes are sampled from each and every page to determine if sector is "dirty", if so sector is erased
Prevents device from sleeping when the firmware detects a series of binary flash page RPC transfers, this increases flash page transfers by %450
when 200mS elapse with the last flash page transfer, normal sleep behaviour is resumed
