LCD- Display to 8051

Thomas Hinst

Hello, i have a problem. I want to connect a LCD-Grafic-Display with a Hitachi HD61202 Controller to a 80c592. Is it possible? Know someone how to do this? Could someone give me a tip?

Thanks

Thomas

    I am not familiar with the controller you use, but usually, it is not possible to connect the display to the databus and then do the rest with some programmable logic, since the timing of the LCDs are strange and slow. What you can do is connecting the databus and the control signals of the LCD to the I/O-Pins of the processor and then "simulate" the timing given in the datasheet. That usually works pretyt well, but keep in mind, that some LCD controller require to do things pretty slowly.
