3.3 Running the Demonstration

To run the demonstration, complete the following steps:

  1. Open CCSTUDIO
  2. Import the "blood_pressure_monitor demo" project inside the SDK demos folder as seen in Figure 3-4
  3. Build the project and program the board
  4. Click on the GUI link inside the README file to setup the demonstration GUI to reach Figure 3-5
Note: Examine the README file to understand the peripherals and pins used for this design.

The following list provides a summary of the instructions to operate the GUI and generate the images shown in Figure 3-6.

  1. Go to the Blood Pressure Monitor tab.
  2. Click on the Start GUI button.
  3. The board starts streaming both ADC channels over UART and the channels are displayed on the GUI windows.
  4. Click the Inflate Cuff button to inflate the cuff to a target threshold pressure.
    1. At this point the program stops the pump at the target pressure and starts to open the valve to deflate the cuff and allow for cleaner sensor measurements.
  5. To stop the demonstration, click on Deflate cuff to open the valve and turn off the pump, and then click Stop GUI.
