DT070CTFT LVDS board components unavailable

Hello

I am trying to find the parts used on the reference design schematic of DT070CTFT display LVDS board and many of them are not in stock anywhere and have a lead time of 1 or 2 years.

Do you know any alternatives I could use for these parts?

CAT4139TD-GT3

TPS65105PWPR

MBR130LSFT1G

 

Thanks

Library supporting DT024CTFT code sample

There's sample code posted on DT024CTFT webpage and it references numerous other C source and header files.  Are these available and if so, where?  I did a quick Google search and didn't find something that looks like Microchip Graphics Library with the references in the code sample.

CT024CTF-TS LCD

Hi,

I understand that the DT024CTFT-TS has a back-lighting system of three LEDs wired in series which requires +9.6V at a constant current If=20 mA mode of operation. Our system has maximum voltage of 5V. 

1. Do you have a similar LCD (Size and Pins) that uses lower voltage for the backlight LEDs?

2. Will the current LED be able to run on lower voltage of 5V and 20 mA?

3. Any suggestions on how to DC-to-DC step-up the 5V to 10V? 

Thanks a lot for your help.

What initialization steps are required when running the DT018ATFT in RGB mode?

For RGB, there is no initialization code to make this work out of the box, just pin configuration.

For MCU and RGB:

The IM[1:0] bits are used to set the MCU interface to either 16 or 18 bit (01 or 11). IM2 selects either Serial (0) or parallel (1) MCU interface. So for example, IM[2:0] = 011 would mean the MCU interface is running in 18-bit serial mode.

The RCM1 bit is used to select either the MCU (0) or RGB (1) interface modes (for writing display data to frame memory).

If the RGB interface mode is selected (RCM1 =... (More)
