FPGA personalities consist of predefined FPGA bitfiles for you to program with myRIO. The LabVIEW myRIO Toolkit provides the following FPGA personalities.
- Default—Supports general I/O, protocols, and interrupt. Use the default personality for control applications.
- High Throughput—Supports high-speed analog or digital data access. Use the high-throughput personality for audio signals and projects in need of waveform data.
 |
Note To use the high-throughput personality, you must install the NI High Throughput Add-On for myRIO. Visit ni.com/info and enter the Info Code ex6g5a to learn about the High Throughput Add-On for myRIO. |
You can choose a personality when you create a myRIO project. With different personalities, you can implement different functionalities and use different channels on the myRIO.
To switch between personalities, right-click a myRIO target in the Project Explorer window, select Switch FPGA Personality, and choose an available personality from the shortcut menu.
|
Note You cannot switch between personalities in myRIO projects that include customized FPGA code, such as the myRIO Custom FPGA Project. |
The following table lists the functionalities and channel numbers that each personality supports.
