Undefined reference to d4dlcd_frame_buffer

[ankurchauhan]

Hi...

I'm using d4d demo code to display string on LCD.

I'm getting error like :

-> undefined reference to d4dlcd_frame_buffer

for the following code  :

D4D_LLD_LCD.D4DLCD_Send_PixelColor(p_CharDes->colorBack);

(void)D4D_LLD_LCD.D4DLCD_SetWindow(p_CharDes->x, p_CharDes->y,

i have definitions of D4DLCD_Send_PixelColor and D4DLCD_SetWindow.

what could be the problem.

Regards

Ankur

Hello Ankur,

This function is part of the D4D low level drivers and is declared in the file common_source\d4d_lldapi.h so please confirm that it is included in your project. I recommend you to take a look into the demo projects that are included in the NXP Embedded GUI Software​.

Best regards,

Earl.
