工业工程驱动并口编程时

Experimenting with the MAX7300/MAX7301 Port Expanders from a PC
	
The MAX7300 and MAX7301 are versatile 28-port general purpose inputs/outputs (GPIO) processor peripherals. Control is made through a high-speed SPI (MAX7301) or I睠 (MAX7300) serial interface. This application note describes a utility program which allows a MAX7301 or MAX7300 driver to be controlled from a PC. The utility can be used as a stand-alone simply to help an engineer become familiar with the registers and functions of the drivers. Moreover, it can be used to 'prove' an application board prototype by directly controlling the MAX7301 or MAX7300 registers before the equipment's software is designed. 

Requirements

A PC running Windows 95, 98, 98SE, ME, NT, 2000, or XP with a parallel printer port configured for either LPT1 or LPT2.

Description

The utility is a Visual Basic 5 program called MAX7300.EXE which requires the standard Visual Basic run time library MSVBVM50.DLL in order to run at all. The program uses the DriverLINX
