LPC2478 + TFT LCD -> How to manage multipe page buffers - Felipe de A N L - Oct 10 13:07:52 2009
Hello folks!
I am trying to mannage multiple page buffers for the TFT LCD on the LPC2478,
I did try to change the UP_PANNEL_ADDRESS and LOWER_PANNEL_ADDRESS registers
on the LPC2478 but there was no result, is there another way of doing it ?
Thanks

I've successfully used a two buffer scheme to play a video:
(Assuming that currently buffer1 is being scanned)
1. Fill buffer2 with next frame.
2. Wait for "Base Address Register Update" interrupt.
3. Set LCD_UPBASE to buffer2.
4. Fill buffer1 with next frame.
2. Wait for "Base Address Register Update" interrupt.
3. Set LCD_UPBASE to buffer1.
4. Goto 1
