Project contracted by IMPCO Technologies Inc., Cerritos, California. This Windows 95 software was written using Microsoft Visual C++ 5.0 and Microsoft Foundation Classes. The purpose of the software is to assist IMPCO in manufacturing a hot-wire gas mass sensor/gas valve component. The operator installs a newly manufactured component and the tester software written by me does the following: Testing functionality of the sensor’s on-board electronic circuitry and processor Bootstrap loading the sensor’s software into a blank (non-programmed) processor Testing/validating functionality of the valve Testing for optimal sensor bridge calibration, calculating needed values Characterizing the sensor, building the calibration tables Building new, custom code for the component under test, programming it into the sensor’s processor Building database of tests for statistical/QA purposes Charting software for engineering maintenance (not completed yet) The tester software required extensive support for non-standard PC hardware. This was implemented by means of universal class library. Modules (device drivers) were written for utilizing the following hardware: Am9315 Timer Counter, Digital IO Board CIO-DAS16/330 Analog Inputs Board RTI802 Analog Outputs Board 68HC811 access through custom 11500bps interface
