The objective of this application is to showcase the GPIO control using Driverlib api calls. The LEDs connected to the GPIOs on the LP are used to indicate the GPIO output. The GPIOs are driven high-low periodically in order to turn on-off the LEDs.
The demo application focuses on showing the required
initialization sequence to enable the CC3200 SPI
module in full duplex 4-wire master and slave mode(s).
The serial peripheral interface (SPI) is a four-wire bidirectional communications interface that converts data between parallel and serial. The SPI module performs serial-to-parallel conversion on data received from a peripheral device, and parallel-to-serial conversion on data transmitted to a peripheral device. The SPI allows a duplex serial communication between a local host and SPI-compliant external devices.
