Hi Forum, I am using CrossWorks, LPC2888 and Nohau LPC2800 board with SSD1338 LCD (128x128). I tried to setup the clock for the LCD and then send the LCD-specific commands to initialize it, and then fill it with red, but the LCD remains black, or not turned on. After the lcd_init() I write red color using the data_out() in a cycle (128x128times). This cycle finishes, so the LCD i...

I know by now that it is not possible to execute from external FLASH memory and simultaneously drive an LCD. Now, this information is very important. Is it possible to execute from external SDRAM and drive an LCD with LCD frame buffer in SDRAM too without LCD flickering? Let's say LCD is 320x240 TFT. Thank you very much ! ------------------------------------

If I execute the startup routine again, LCD comes back to normal...

I already have a 2*16 LCD interfaced to an LPC2129 but, to be honest, it sucks, (the LCD interface was designed long ago by someone else). It works by polling the busy line to see if the LCD is ready for the next command. This makes the display slow, (the minimum 1ms OS sleep is too long for many commands), and wastes CPU cycles. I want to make the busy flag generate an interrupt when it goes n...
