OLEDs / NHD-2.8-25664 OLED Display
« on: September 08, 2014, 10:57:39 AM »
hi everyone,

i am using an oled in my project but am have great difficulty in getting it to work.

i am using parallel 6800 interface.

i can send command oxA4  and the display goes all blank.
i then send command 0xA5 and display all lit.

i have used the init sequence as per data sheet and i get display showing some pixels while other and un-lit (semi random).

i have noticed,  after sending data (instruction)  the next command instruction is ignored. this leads me to thinks there is problem with my sending data command.

i can't see much difference between command and data instruction except the DC line.

i have  run Checkerboard_25664() and i get nothing.

please help

many thanks
