The design of a computer system which directly controls tunnel barrier width in a scanning tunneling microscope (STM) is described. This capability allows STM scans to be performed at a speed which is automatically determined by the roughness of the surface under study. The computer system is inexpensive and designed with readily available components for the VME bus.
