  • Product LCD-00569 | about 4 years ago

    Hi guys,
    I’m using the LCD display in a project. I used the Excellent Tutorial by Jim Lynch and my LCD is working.
    BUT
    the problem is …. it’s really SLOW
    It takes ages to display string or clear the screen (and I mean really slow… like 1.5 minutes or so :S)
    I’m using the LCD with epson controller but using xilinx spartan-3E board and 32-bits microblaze processor. The main bus clock is 80 MHz, and the data transferred to LCD using xilinx SPI core. The bus frequency ration to the SPI clock is 16.
    Can anybody help me with this… the functionality of the LCD is crucial to my project since the actions are menu driven through the LCD :S

No public wish lists :(
