ValveDriverModule()

Description

ValveDriverModule interfaces MATLAB with the Bpod Valve Driver Module. Each valve driver module adds 8 additional solenoid valves to a Bpod State Machine setup.

A ValveDriverModule object is initialized with the following syntax:

V = ValveDriverModule('COM3');

Where COM3 is the valve driver module's serial port.

The valve driver module is controlled in 2 ways:

• Setting the ValveDriverModule object's fields
• Calling the ValveDriverModule object's functions (its methods)

Object Fields

• Port
  • ArCOM Serial port object
• isOpen
  • An 1x8 array of valve states.
    • Each valve state is 0 (closed) or 1 (open)
    • Setting the array will automatically update the device, opening and closing valves to match isOpen

Object functions

• openValve(valveID)
  • Opens a valve specified by valveID (range = 1-8)
• closeValve(valveID)
  • Closes a valve specified by valveID (range = 1-8)

Cleanup

• Clear the ValveDriverModule object with clear:

  V = ValveDriverModule('COM3');
  % ... Use the valve driver module
  clear V
  

• Clearing the object releases the serial port, so other applications can access it.
• If a ValveDriverModule object is created inside a MATLAB function, the object is cleared automatically when the function returns.
