6.1 Description of Hitex LPC1850 board and LogicPD panel setup
The supplied example software is designed to run on a Hitex LPC1850 evaluation board
that is connected to a LogicPD LCD panel (model number LCD-6.4-VGA-10R-A). This
module contains a VGA (640 x 480) TFT Sharp LCD (LQ64D343).
The LCD ribbon cable should be attached to connector labeled “LCD” on the LPC1850
board. The jumpers can be left in the default position when shipped from the factory.
The Hitex LPC1850 board has 8 MB of external SDRAM using a 1 Mbit x 16bit x 4 bank
SDRAM device. This SDRAM memory will be used as the LCD frame buffer memory for
this example. The SDRAM memory resides at address:
0x2800 0000 - 0x287F FFFF using DYNCS0
Using the 640x480 16bpp RGB1:5:5:5 mode, the frame buffer uses 614 kB of SDRAM
starting at address 0x28000000.
The parameters for the LogicPD LCD panel are configured in lcd_params.c; this panel is
configured for operation in 1:5:5:5 mode.
