Dear All,
I'm new to uClinux and I need to replace an original LCD screen (240x320)
which is in the "Embedded Artists LPC2478 OEM Board" to a new LCD screen:
TIANMA TM032LDH18 (resolution 240x400). I think i need to configure some
register of the new TIANMA LCD screen, but i do not know where to change in the
file, is there anybody who has the knowledge of doing this porting?
Thanks
Porting TIANMA LCD screen to Embedded Artists LPC2478 OEM Board

Hi,
as far as I remember, the EA board has a TFT with RGB connection
(typically 18 / 24 pins for RGB + VSYNC + HSYNC + clock) connected and
this TFT is driven by the LPC2478's built-in display controller. I could
not find the TM032LDH18 on Tianma's website, but I assume it's a TFT
display with a display controller already build-in - so it has to be
driven with a 8 / 16 or 18 bit bus with Write and Read signals instead.
If this is the case, you need to modify the hardware accordingly as well.
So you should be aware that this is not a trivial task you have to do ...
Regards
Herbert
