Other functions support the LCD module to adjust its contrast and to turn
the white CCFL backlight on and off. A variable resistor between two of
the LCD module’s terminals sets the contrast, which is set either by soft-
ware or manually, depending on the jumper setting on header JP2. Once a
contrast value is set, it will be maintained. A single programmed I/O bit is
used to turn the backlight on or off.
The controller chip used in OP7100’s sold before 2006 supported either
32K or 64K of SRAM. These OP7100s were designed using a dual-
footprint SRAM to accept either one 32K or two 32K SRAM. One 32K
part was standard.
OP7100 units sold after June, 2006, have a new LCD controller chip because
the previously used LCD controller chip is no longer available. The new LCD
controller chip has 32K of internal SRAM. Figure 3-9 shows the area of the
OP7100 that changed to accommodate the new LCD controller chip. The new
LCD controller is not 100% code-compatible with the old chip—the New
LCD Controller Chip section on p. 73 explains how to handle programs
developed for an OP7100 for the older LCD controller chip.
