Get to Know the MPC830x-TLCD

MPC830x-TLCD

The MPC830x-TLCD is a 3.2" QVGA LCD touch screen with a 12-key capacitive touch keypad. The LCD panel
can be driven with a parallel bus, SPI or RGB display interface signaling.

Configuring
Display

Configure the display interface as a
parallel bus interface (DIF_SEL=OFF), SPI
interface (DIF_SEL=ON, DISABLE_SPI=ON
and DISABLE_RGB=OFF) or an RGB
interface (DIF_SEL=ON) with optional SPI
depending on the DISABLE_SPI setting.
Set the TFT_PS0-3 settings in accordance
with the selected display interface. See
configuration switch settings.

Mount
Display

Note: Configure the module before
mounting since the configuration switch
is inaccessible once mounted. Ensure
that the display connector is properly
aligned to the mating connector and press
down. Insert at least one screw through
an aligned mounting hole on the mating
board into a mounting standoff to secure
the module.
