I have never worked with the details of a TFT interface, but I would guess it would
not be possible because TFT usually special hardware support. I believe the
screen has to be constantly refreshed since it does not have a memory.
You should be able to find a fraphics display which interfaces via SPI or UART. They
make them with processors and memory, so they can easily interface with
a device like a panda.
If all have is a TFT display and a panda, then I think you have nothing.
Controlling FEZ Touch is done through the ILI9325 LCD controller.
ILI9325 also has the RGB interface. In RGB interface mode, the display data is written into the GRAM through the control signals of ENABLE, VSYNC, HSYNC, DOTCLK and data bus DB[17:0].
The display operation via the RGB interface is synchronized with the VSYNC, HSYNC, and DOTCLK signals.
Is panda able to manage a display on ILI9325 via RGB interface?
“Note that FEZ Panda (based on USBizi chipset) doesn’t have high level graphics libraries like FEZ Cobra (based on EMX module) so you can’t load JPG and GIF directly but GHI provides graphical libraries to aid in drawing on this display.”
