Using ADSP-BF527 EZ-KIT Lite
LCD Module Interface
The EZ-KIT Lite features a Varitronix VL_PS_COG_T350MCQB TFT
LCD module with touchscreen overlay. This is a 3.5” landscape display
with a resolution of 320 x 240 and a color depth of 24 bits. The interface
is an RGB-888 serial parallel interface, eight bits of red, followed by eight
bits of green, and then eight bits of blue.
To configure the PPI interface, refer to the LCD software example located
in the
…\Blackfin\Examples\ADSP-BF527 EZ-KIT Lite\POST
subdirectory
of the Vi+ installation directory. The values are obtained from
the timing characteristics section of the VL_PS_COG_T350MCQB
datasheet.
The interface is set to control frame sync 1 and 2 (
PPIFS1
,
PPIFS2
)
natively from the ADSP-BF527 processor. The LCD data enable (
DEN
) is
controlled by a Xilinx CPLD XC9536XL. You do not need to change
CPLD code, which should work for the VL_PS_COG_T350MCQB dis-
play. The verilog source code for the CPLD can be found in the reference
resource zip file at:
http://www.analog.com/en/epHSProd/0,,BF527-HARDWARE,00.html
.
The LCD module can be disconnected from PPI by removing the jumper
on
JP2
. Refer to
“LCD PPI Jumper (JP2)” on page 2-21
for more
information.
