All digital pins of the device can be used as general-purpose input/output (GPIO). GPIOs can be used for various purposes. The GPIO module on the CC3200 consists of four GPIO blocks:

Each GPIO block provides eight GPIOs. The GPIO module supports 30 programmable GPIO pins, depending on the peripheral used.

Application details

The objective of this application is to showcase GPIO control using Driverlib API calls. The LEDs connected to the GPIOs on the LaunchPad are used to indicate GPIO output. The GPIOs are driven high and low periodically in order to turn the LEDs on and off.

Source Files briefly explained


  1. Run the reference application.
    • Open the project in CCS/IAR. Build the application and debug to load to the device, or flash the binary using UniFlash.
  2. Verify the LaunchPad LEDs (D5, D6 and D7) toggle on and off.
