Hello Manish,
I think you have some wrong understanding of what this MCU can do.
[list]
[*] our MCU has a TFT interface. This is a digital interface. There is no VGA signal available on this board. VGA is analog.
[*] our TFT controller can do in maximum 1024 x 768 pixels, but I have doubts that you can fulfill the VGA spec for this resolution (60-72 MHz refresh rate is too high for our MCU, there is too much data to shuffle from the frame buffer to the display)
[/list]
If you want to display images with this resolution you need to use another class of controllers, typically one of these so called SoCs, like Rasperry.
NXP has a TFT-to-VGA device, but the same problem applies here as well: the LPC4300 MCU with its TFT interface is not powerful enough to drive this resolution (as well as all other NXP MCUs with TFT interface).
Regards,
NXP Support Team.
