MotoHawk PCA9745B LED Definition

This MotoHawk blockset allows control over a 16 channel constant current LED driver device produced by NXP. Refer to the PCA9745B device datasheet for detailed explanation of the operation and tunable controls. These blocks are available to access the device:

• Definition block - Instantiates PCA9745B resource and attaches reference name, so that other blocks can access by reference
• Group Definition block - Instantiates PCA9745B Group resource and attaches reference name, so that other blocks can access by reference
• LED Definition block - Instantiates PCA9745B LED resource and attaches reference name, so that other blocks can access by reference
• Global Set block - Provides the global settings applicable to all LEDs
• Group Set block - Provides the settings applicable to a PCA9745B Group
• LED Set block - Provides the settings applicable to a PCA9745B LED
• IO FaultStatus - The standard MotoHawk FaultStatus block can be used to access faults.
• Detailed FaultStatus - Alternatively, detailed fault status can be obtained. IO FaultStatus and Detailed Fault Status should not be used at the same time to access PCA9745B faults.
