Operating the GUI
1. After the hardware and software installations have been completed, make sure the
MAX32630FTHR is connected to the PC using the USB cable.

4. Press the scan button to auto-detect the Smart Sensor board that shows as PPG under
"Connected Devices".
5. Click "Launch Tool" to run the MAXREFDES220#-specific features.
6. Configure the PPG settings as desired. Do not change the FIFO settings from their default
values.

Updating the MAX32630FTHR firmware
These steps are only necessary if the MAX32630FTHR does not initialize as described above.
1. Navigate to the Maxim Integrated website, enter MAXREFDES220# into the search tool. Select
the entry for MAXREFDES220# in the Product Results section.
2. From the product page, select Design Resources and download the files under "Firmware Files".
3. Extract the .bin file into any directory.
4. Connect one end of the ribbon cable to the black header J4 on the MAX32630FTR.
5. Examine the other end of the ribbon cable carefully. One side of the cable going into the black
header SWD is marked by the red wire. Connect the cable and SWD header, making sure the
red wire is furthest from the letters SWD.
6. Connect a mini USB cable between the USB connector labeled HDK and the PC.
7. Open a File Explorer window. The programming adapter shows as a new USB drive.
