MCX-N947 How to output 8080 8-bit data for LCD(RGB565)

[billie]

Hi,

I'm going to use new LCD which has 8080 8-bit interface with MCXN947.

So, I'd like to check 8080 8-bit data output of MCXN947 with LCD-PAR-S035.

As you know, LCD-PAR-S035 can be changed 8080 8-bit mode from 16-bit mode.

So, I changed that fsl_flexio_mculcd.h and pin_mux.c.

- fsl_flexio_mculcd.h : #define FLEXIO_MCULCD_DATA_BUS_WIDTH 8UL

- pin_mux.c : Flexio_D16 ~ FlexIO_D23.

However, I can't see correct output on the LCD(LCD-PAR-S035) like attached images.

Please let me what to fix in order to get correct output.

Regards,

Billy(Seongjin)

Hi Celeste,

Here are the version of SDK and demo example.

In my testing, latest version SDK doesn't work with LCD-PAR-S035.

• SDK : SDK_2_x_MCX-N9XX-EVK - 2.16.000
• Demo example :  mcxn9xxevk_lvgl_demo_benchmark_bm
