SHARP Memory Display Breakout - 2.7" 400x240 with nrf52840

[Muhammad]

Hi,

I want to use SHARP Memory Display Breakout - 2.7" 400x240 with nrf52840 development kit. I have to interface the lvgl library for the graphics development but from the documentation, I could not figure out how to connect and there is no basic code for interfacing with the nordic SDK. Please suggest any type of reference for examples if available.

Any kind of input or help will be appreciated.

Thanks in Advance,

Hi,

Thanks for the detailed response. I have tried the lvgl example in nrfConnect SDK and the sample you provided. There are two cases that I tested,
1. When I compile the standard lvgl example from the nrfConnect sdk, it compiles and when I flash it to the nrf52840 DK and connect the pins as you described in the previous comment, the LCD does not show any sign of being on or off. Maybe some pins you described or SPI configurations/Pins need changes. Can you guide how I can find which pins are configured for the spi in a specific project?

2. When I add your sample project in the VScode it gives the following error in the compilation step and I can not find any way to resolve it.

Can you comment on this how we should proceed here?

Hi Muhammad, sorry for the delay.

It looks like you are using nRF Connect SDK v1.5.1. The sample I uploaded is targeted for v2.0.2. Try changing to v2.0.2 unless you have any reason to use v1.5.1. You may change the SDK version by going to the "Welcome to nRF Connect tab" and change it under "Quick Setup". Remember to change both the SDK version and toolchain.
