Executing Sample Programs

Vth and Capacitance Measurement Program

To use the VFP data upload library

If you want to use your VFP data in the program, change the program as follows. Before executing the program, you need to create the VFP data and save it to a file on diskette. And you must link the VFP Data Upload Library to the program. For details, refer to “Using the Virtual Front Panel (VFP) Utility” on page 5-4 and “Using the VFP Data Upload Library” on page 6-22.
