VGLite for RT1160

[erikraynolds]

Hello,

I am trying to run evkmimxrt1160_lvgl_demo_widgets_bm_cm7 demo and enable vglite. I am setting the LV_USE_GPU_NXP_VG_LITE variable to 1 in lv_conf.h.

/*Use NXP's VG-Lite GPU iMX RTxxx platforms*/
//#define LV_USE_GPU_NXP_VG_LITE 0
#define LV_USE_GPU_NXP_VG_LITE 1

and having compilation problems:

../lvgl/lvgl/src/gpu/lv_gpu_nxp_vglite.c:42:10: fatal error: vg_lite.h: No such file or directory
42 | #include "vg_lite.h"
| ^~~~~~~~~~~
compilation terminated.
make[1]: *** [lvgl/lvgl/src/gpu/subdir.mk:30: lvgl/lvgl/src/gpu/lv_gpu_nxp_vglite.o] Error 1
make[1]: *** Waiting for unfinished jobs....

Is the VGlite supported for RT1160? If so, how to enable it correctly?

Hi @erikraynolds ,

  VGLite code you can refer to SDK:

 SDK_2_11_0_MIMXRT1160-EVK\boards\evkmimxrt1160\vglite_examples

  Your mentioned code is the lvglite, if modify the code like you, really meet issues, even add the related header file, still have other issues, so I think the lvglite still have support issues for that item.

   If you still need it, I recommend you use your company email create a new question post, then we will help you to check internally. Seems your ongoing email is the 3rd part email.

Best Regards,

Kerry

I also want to know how to use RT064. Now I use double buffering to drive an 800*480 pixel screen and find that the frame rate is only about 15 frames.
