GUIX single frame buffer

vipuljain91 — Thu, 16 Mar 2023 07:57:24 GMT

I am working on MIMXRT1062 board . I took the reference of example code of "EVK-MIMXRT1060-guix_washing_machine". In this example it is using two frame buffer of 480*270 pixel for LCD.

The board I am using has display of 320*480 resolution, and I have to use single frame buffer only.

Please guide me what are the necessary changes I need to made for this.

Hello @vipuljain91,

You could try modifying those values in display_support.h file:

[guix_washing_machine -> board -> display_support.h]

Please modify the DEMO_PANEL_WIDTH, DEMO_PANEL_HEIGHT, and DEMO_BUFFER_COUNT (lines 25 to 29) to the values your display has. Example:

#define DEMO_PANEL_WIDTH 320 #define DEMO_PANEL_HEIGHT 480 #define DEMO_BUFFER_COUNT 1

Hope this helps.

Best regards, Raul.
