22 2013: The ASYN Software Module EPICS Writing ASYN Driver Support u Since the interface to the device support layer has been written for most common
{"Image DocumentName": "Writing ASYN Driver Support", "Image ImageDescription": "Since the interface to the device support layer has been written for most common EPICS records, we are more likely to need to write an ASYN driver. Starting design of a new ASYN based driver. Decide whether your device is synchronous or asynchronous (timing) Choose a number of commands which your driver will implement. Identify which standard interfaces are appropriate for communicating with the device. A driver must maintain a data structure for all its internal storage. Common practice for most drivers \u2013 not just asyn. A pointer to this structure will be passed around as an argument to the various callbacks to the driver code.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
