Is it possible for nRF52840 to drive an 240RGB x 320 LCD

Ryon_pan

Hello,the SDk is nRF5_SDK_15.0.0_a53641a,the MCU is 52840.

I want to  memory map it and refresh it .

that's 240x320 x bytes per pixel, it's 16-bit RGB, so 240x320x2 = 150k which is the RAM Smaller than on the nrf52840(256K).

So my question is that if I want to  memory map it and refresh it .is it possible for 52840 to drive the LCD?

thx.

    Hello,

    I assume that the display uses SPI as the data bus?

    There is an example called gfx, located in SDK\examples\peripherals\gfx. You can use that as a starting point to test your LCD screen. I don't know if your screen is any of the displays in the example, but it may be a good place to start either way.

    As you say, memory is a challenge. I don't know if you intend to display images, text or figures, but you may not need to store all pixels individually, depending on how you use it.

    Best regards,
