NHD-3.5-320240JF-ASXP-CTP - SPI Configuration

Artur Vieira

Hi

 

I am interested in using this display `NHD-3.5-320240JF-ASXP-CTP` in a new project. I have a question since up to now the RGB LCDs I have used didn't have SPI interface.

According to the display datasheet it seems that there some parameters that should be adjusted via SPI. Is there any special configuration required to be sent via SPI? Or all the configurable values (Gamm, VCOM, etc..) already configured via `OTP`?

One other question, is it possible to rotate the screen (image) via SPI configuration?

Thank You

    Hi Artur,

    The NHD-3.5-320240JF-ASXP-CTP display does allow you to adjust certain parameters over SPI such as timing parameters and display mode setting.  However, in most cases, it is not necessary to adjust these registers.  The display should be able to be controlled with an RGB controller without any adjustments to the SPI-accessible registers.

    The ST7272A IC does not have a built-in "rotate" function, but it should be possible by adjusting the "Display Mode Setting" register.
