Hi Allan,

I am not sure I fully understand your question.  Have you tried to instantiate a controller and load a template file, and received errors, or are you not that far along?

Unfortunately motor does not seem to contain an example for your controller, but it does contain examples for lots of other controllers that use devMotorAsyn.c and asynMotorController.cpp.

Look in motor/iocBoot/iocWithAsyn/st.cmd.mcb4b for a simple example.

It creates a controller object with

MCB4BCreateController("MCB4B1", "serial1", 4, 100, 5000)

In your case I believe this would be:

PI_GCS2_CreateController(const char *portName, const char* asynPort, int numAxes, int priority, int stackSize, int movingPollingRate, int idlePollingRate)

and then loads a template file with several motor records:

dbLoadTemplate "motor.substitutions.mcb4b"

You need to create a template file for your motors.

The motor module is being split into separate repositories for each controller type.  Each repository will contain an example IOC to help with these types of questions.  These example IOCs will require help from the community, since at the APS we don't have all of the types of controllers that are supported, so we can't test examples.

Mark

Subject: asynMotor device support and the motor specific driver (asynMotorContorller)

Hello all,

I need a clarification about the motor module. The asynMotor device support (defined in 'motorApp/MotorSrc/devMotorAsyn.c') tries to find an asynDrvUser interface in init_record function, so that it can find the driver commands with findDrvInfo function. I'm using the asynMotorController driver that implements the PI's command set GCS. How can I connect this driver with the motor record through asynMotor device support?

Additional information:

A class diagram of the PI sources (please ignore the error message; using motor 6-11 now)
