# CC3200
## Overview
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:
* GPIO A0
* GPIO A1
* GPIO A2
* GPIO A3
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
* **main.c**: Contains the core logic to drive GPIOs and inturn blink the LEDs.
* **gpio\_if.c**: Contains the Driverlib API calls to drive the GPIOs
* **pinmux.c**: Generated by the PinMUX utility. GPIO pins are brought out on
the device boundry using the Driverlib Pinmux API calls.
* **startup\_\*.c** - Initialize vector table and IDE related functions
## Usage
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](http://processors.wiki.ti.com/index.php/CC3100_%26_CC3200_UniFlash_Quick_Start_Guide).
2. Verify the LaunchPad LEDs (D5, D6 and D7) toggle on and off.

//! A helper macro for building scatter-gather task table entries.
//!
//! \param ulTransferCount is the count of items to transfer for this task.
//! \param ulItemSize is the bit size of the items to transfer for this task.
//! \param ulSrcIncrement is the bit size increment for source data.
//! \param pvSrcAddr is the starting address of the data to transfer.
//! \param ulDstIncrement is the bit size increment for destination data.
//! \param pvDstAddr is the starting address of the destination data.
//! \param ulArbSize is the arbitration size to use for the transfer task.
//! \param ulMode is the transfer mode for this task.
//!
//! This macro is intended to be used to help populate a table of uDMA tasks
//! for a scatter-gather transfer. This macro will calculate the values for
//! the fields of a task structure entry based on the input parameters.
//!
//! There are specific requirements for the values of each parameter. No
//! checking is done so it is up to the caller to ensure that correct values
//! are used for the parameters.
//!
//! The \e ulTransferCount parameter is the number of items that will be
//! transferred by this task. It must be in the range 1-1024.
//!
//! The \e ulItemSize parameter is the bit size of the transfer data. It must
//! be one of \b UDMA_SIZE_8, \b UDMA_SIZE_16, or \b UDMA_SIZE_32.
//!
//! The \e ulSrcIncrement parameter is the increment size for the source data.
//! It must be one of \b UDMA_SRC_INC_8, \b UDMA_SRC_INC_16,
//! \b UDMA_SRC_INC_32, or \b UDMA_SRC_INC_NONE.
//!
//! The \e pvSrcAddr parameter is a void pointer to the beginning of the source
//! data.
//!
//! The \e ulDstIncrement parameter is the increment size for the destination
//! data. It must be one of \b UDMA_DST_INC_8, \b UDMA_DST_INC_16,
//! \b UDMA_DST_INC_32, or \b UDMA_DST_INC_NONE.
//!
//! The \e pvDstAddr parameter is a void pointer to the beginning of the
//! location where the data will be transferred.
//!
//! The \e ulArbSize parameter is the arbitration size for the transfer, and
//! must be one of \b UDMA_ARB_1, \b UDMA_ARB_2, \b UDMA_ARB_4, and so on
//! up to \b UDMA_ARB_1024. This is used to select the arbitration size in
//! powers of 2, from 1 to 1024.
//!
//! The \e ulMode parameter is the mode to use for this transfer task. It
//! must be one of \b UDMA_MODE_BASIC, \b UDMA_MODE_AUTO,
//! \b UDMA_MODE_MEM_SCATTER_GATHER, or \b UDMA_MODE_PER_SCATTER_GATHER. Note
//! that normally all tasks will be one of the scatter-gather modes while the
//! last task is a task list will be AUTO or BASIC.
//!
//! This macro is intended to be used to initialize individual entries of
//! a structure of tDMAControlTable type, like this:
//!
//! \verbatim
//! tDMAControlTable MyTaskList[] =
//! {
//! uDMATaskStructEntry(Task1Count, UDMA_SIZE_8,
//! UDMA_SRC_INC_8, MySourceBuf,
//! UDMA_DST_INC_8, MyDestBuf,
//! UDMA_ARB_8, UDMA_MODE_MEM_SCATTER_GATHER),
//! uDMATaskStructEntry(Task2Count, ... ),
//! }
//! \endverbatim
//!
//! \return Nothing; this is not a function.
