Overview
Updates the sample rate of each module wire in the system
Discussion
The module is designed to update the sample rate of all the wires in the system.
...
In the typical use case, when the sample rate of the running target changes it causes the target firmware to use Control I/O to change the .sampleRate variable thus allowing the running layout to match processing to the new sample rate running on the target
Type Definition

INT32 updateActive; // Flag to control the state of the boolean output pin.
FLOAT32* wireSR; // Array of all modules wire sample rate info
} ModuleUpdateSampleRateClass; |
