3.3 DCP Settings

This section describes the graphical user interface configuration of both the DSP and the ADS1278 tabulator in the Data Converter Support Tool.
The interface software for this example project was generated using these settings.

DSP Tab Settings

Converter Tab Settings

`- Serial Port`	`: McBSP1`
`- Serial Port Format`	`: FS, TDM, Fixed`
`- Conversion Mode`	`: High-Speed`
`- Master Clock Frequency`	`: 28125.000kHz`
`- Power Down`	`: All unchecked`

3.4 Application Settings

Sample Buffer

The Sample Buffer is a data field within the C source code where the samples read from or stored to - dependent on the converter type.
This data field is declared in the application file (main.c).
In this example project the Sample Buffer has/have the following parameter:

`- Name`	`: r_buffer1`
`- Size`	`: 2048`
`- DataType`	`: int`
`- Name`	`: r_buffer2`
`- Size`	`: 2048`
`- DataType`	`: int`

3.5 Code Composer Studio Settings

How To Display Data Samples

This section describes how to graphically watch samples collected from the data converter and, thus, verify the proper work of the converter.

1. Start Code Composer Studio

2. Open the Project

3. Download the $PrjDir\Debug\ADS1278-C6713-CCS3v1.out file to the DSP (DO NOT recompile)

4. Open three Graph Window (parameters are listed below)

5. Run the Program

6. Stop the Program

7. Observe the graph windows: You should see collected data samples in the graph window. Buffer 3 will show more signal periods since it was filled using function dc_readsample(), which is slower.

Parameter for the Graph Window(s):

`- Graph Title`	`: Buffer 1`
`- Start Address`	`: r_buffer1`
`- Acquisition Buffer Size`	`: 4096`
`- Display Data Size`	`: 512`
`- DSP Data Type`	`: 32-bit signed integer`
`- Autoscale`	`: on`

Since no compiling took place by now (software is binary the same as during the creation of this example project) the user can check the hardware.
In case the system does not work as expected the problem lies most probably in the hardware.

3.6 Exposed Functions

ADS1278_getFinishedBufferAddress()

- unsigned int: Address of the buffer

- TADS1278 *pADS : Pointer to the data converter object

ADS1278_getFinishedBufferSize()

- unsigned int: Size of the buffer

- TADS1278 *pADS : Pointer to the data converter object
