5-3 EPLD Test
The file used for the test can be found in the “Software\Example\USB-IK01\EPLD” folder of
the CDROM, and download “epld.hex” and test it.
When executed, the values of PCF8574 and 8051 port A are periodically read and transmitted
through the serial port. The transmitted contents can be checked by using “COMM.exe”, and LED
1/2 lights up periodically. Here, if “Switch #1” or “Switch #2” is pressed, the input value is
changed.
It can be confirmed by looking at [Figure 5-3].
