Hardware and Software Requirements
The MLX71122 program has been developed for Windows XP and has been tested for later Windows ver-
sions. The program uses TVicPort I/O driver to interface to the parallel port.
The EVB71122 can be used either with a USB-SPI converter connected to the PC’s USB port or it can be
directly connected to the PC’s printer port (LPT). If the LPT port is used then port addresses 0x278, 0x378
and 0x3BC (hexadecimal) are supported. A programming cable with a male 25-pole SUB-D connector can be
purchased together with the evaluation board EVB71122.
The following LPT ports can be connected to the corresponding IC pins:

If the PC’s USB port is used, a USB-SPI converter is required. It is available on request or can be purchased
together with the evaluation board EVB71122.
Note that pin 7 of the MLX71122 (SPISEL) is connected to logic HIGH on the EVB71122. This is to set the
receiver to SPI mode.
