Section 6. System Testing

6.1 Introduction

This section will first explain how to program the control program into FLASH memory of the MC68HC908QT2 microcontroller. It will then, in detail, provide functional testing of both hardware and user software for the ASB520 infrared remote control reference design.

6.2 Hardware/Software Testing Summary

Because the PC board has minimal user interface, hardware testing will be performed in stages.

•First the control program will be programmed into the MC68HC908QT2’s FLASH memory.

•The keyboard and red LED will be tested next.

•Finally, the ASB520 PC board will be used to control a DVD.

6.3FLASH Programming

The following steps are used to initially program the MC68HC908QT2:

1.If installed, remove the batteries from the battery holder located on the bottom of the PC board

2.Remove jumpers JP1–JP4.

3.Connect the P&E Microcomputer Systems, Inc. MON08 Cyclone’s ribbon cable from the programmer to J1, noting the location of pin 1 on J1.

Follow the P&E Microcomputer Systems, Inc. instructions to program the MC68HC908QT2, with the remote control program file. The file name to program into the device is ASB520.S19.

After FLASH programming is complete, disconnect the Cyclone’s ribbon cable connected to J1 of the ASB520 PC board.

In a production environment, the Cyclone Programmer can be setup so that a single press of a button will initiate an automatic programming operation. The Application Program would be pre-loaded into nonvolatile memory in the Cyclone and no PC would need to be present during production programming.
