NHD-4.3-480272EF-ATXL

Hi, I'm new to this so please forgive a potentially silly question.

I'm using a pi-pico to talk to the ST7282T2 driver for the TFT display.  I have it working via the parallel interface but I'd like to change it to serial.  The ST7282T2 data sheet says I need to pull PARA_SERI low - however it doesn't appear that pin is exposed in the FPC Pin Out.  Am I misunderstanding something, or is this panel/controller hard wired to be only parallel?

Thanks very much in advance!

    Hello,

    Thank you for the interest in our NHD-4.3-480272EF-ATXL display. The display is hard wired internally for 24-bit RGB. If you are looking for a display that uses SPI, I would recommend looking into our EVE2 TFTs as they interface with SPI/D-SPI/Q-SPI.

    Hi - I have a couple of follow up questions...

    Can I use DE Mode timing (no SYNC) or am I required to use SYNC-DE mode or SYNC mode (no DE).  The ST7282T2 supports all three but from my understanding it looks like it's hard wired to only do SYNC-DE or SYNC.  Can you confirm or correct me?

    Also on https://www.newhavendisplay.com/specs/NHD-4.3-480272EF-ATXL.pdf it shows the HSYNC pulse width as being 1 DCLK however on the controller datasheet https://www.newhavendisplay.com/resources_dataFiles/datasheets/LCDs/ST7282T2.pdf it shows HSYNC pulse width as min 2 DCLK and typical 4 DCLK.   I assume it should be 4 and the first sheet is incorrect?

    Many thanks in advance!

    I'm trying to build an application on  NHD-4.3CTP-SHIELD-L . But the application I'm building will be Portrait mode. And all the examples I have seen so far related to this screen are in landscape mode.
    How can I achieve portrait mode in this screen?

    Thanks in advance
