6.1Additional Driver Specific Map Descriptor Parameters
What happens if you want to poll for one specific type of data more frequently than others ? What if you want more control of the location of where data is stored ? What happens if you want to do diagnostic polls … ?
To be able to achieve solutions to any of these types of questions the driver offers advanced configuration by adding to and extending the map descriptors specific to the Dart Serial Driver.
