E
The bit-banging SPI diagnostic utility transmits data
using synchronous serial format (similar to Motorola’s
68HC11 SPI interface). The SPI interface sends and
receives data simultaneously on separate pins. Parallel
port pin 2 drives the CLK_P, pin 3 drives CS_P, and pin
4 drives DIN_P.
The data to be sent is 8-bit data represented by a two-
digit hexadecimal DAC code. The DAC code ranges
from 0x01 to 0xFF. The output is at the higher limit, 90V,
when the DAC code is 0x01, and at the lower limit, 40V,
when the DAC code is 0xFF. The DAC code is entered
in the “Data bytes to be written” box and transmitted by
clicking on Send Now.
Troubleshooting
Problem: Cannot find the MAX1932 EV kit parallel
port connection.
Ensure that the I/O extension cable is connected to a
parallel port and not to a SCSI or other type of port.
Verify that the supplied LPTCON.VXD is in the same
directory as MAX1932.EXE. If a local printer driver is
installed, temporarily disable it. The software does not
work if the program icon is dragged onto the Windows
desktop.
