EPICS module for the LLRF AMC card low level driver llrfAmc. It uses AsynPortDriver for its integration into EPICS.
The modules must be loaded in your IOC in order to configure the LLRF AMC cards. see README.configureDriver.md for details on how to load the module.
When the module is loaded, it will:
- Detect the type of AMC cards used in your application,
- Automatically configure the AMC cards.
The module will also automatically generated asyn parameters which can be used to get information and send commands via PVs. see README.parameterList.md for more details.
The cards are detected based on the devices defined in the YAML files. The llrfAmc driver will look for the DownConverter and UpConverter devices under /mmio/AppTop/AppCore:
- First, it will look for the DownConverter device. Currently, only the device called
AmcMrLlrfDownConvertis supported. - Then, it will look for a UpConveter device. Currently there are two type of devices supported:
- The Gen1 UpConverter device called
AmcMrLlrfUpConvert, - The Gen2 UpConverter device called
AmcMrLlrfGen2UpConvert
- The Gen1 UpConverter device called
If the DownConverter or either of the UpConverter devices is not found, the llrfAmc will thrown an std::runtime_error exception.
When the module is loaded, it will run the initialization sequence to configure both the DownConverter and UpConverter cards. Therefore, it is important that the default YAML configuration is already loaded when this module is loaded in your application.
