hey guys

i have a dmf-5005 ny/ly/ake lcd (uses the t6963 controller).

i have got it hooked up to an atmel mega128 processor (data on port c and control on port d - wr=bit6, rd=bit7, ce=bit4, cd=bit5, reset=bit1)

i am using c to program the microcontroller.

i have attempted the initialisation routine, suggested in the datasheets, but to no avail. the screen still stays blank.

can someone help me please?
my c code is as follows... sorry its so long.....

thanx
simon
