dabs Device API

dabs is ScanImage’s hardware abstraction layer. Every piece of hardware ScanImage® knows about - a DAQ, a stage controller, a PMT, a shutter, an SLM, a camera - is a dabs resource, and every resource is registered in a single, process-wide resource store.

That uniformity is what makes ScanImage scriptable at the hardware level: once you have a handle to a resource, the same reserve / configure / act pattern applies whether it is a Thorlabs stage or a vDAQ analog output.

hRS = dabs.resources.ResourceStore();      % the singleton store

hRS.filterByName('vDAQ0')                  % one resource by name
hRS.filterByClass('dabs.resources.devices.MotorController')   % all of a kind

Note

dabs is a device layer, not a ScanImage layer. A dabs device does not know what ScanImage is doing with it, and can be driven from a plain MATLAB script with ScanImage closed - which is what makes it useful for bench work and for writing your own drivers.
