Two new LCD panels for i.MX RT EVKs are now available. However this new LCD panel is not supported by the i.MX RT1160/RT1170 eIQ demos in MCUXpresso SDK 2.11, and so some changes will need to be made to use the new LCD panels.
For i.MX RT1050/RT1060/RT1064 eIQ Demos in MCUXPresso SDK 2.11 that use the LCD:
The eIQ demos are only configured for the original panel. However because the eIQ demos do not use the touch controller, all eIQ demos for i.MX RT1050/1060/1064 will work fine with both the original and new LCD panels without any changes.
For i.MX RT1160/RT1170 eIQ Demos in MCUXPresso SDK 2.11 that use the LCD:
The eIQ demos are still only configured for the original panel. MCUXpresso SDK 2.12 will support both panels when it is released later this summer. In the meantime, for those who have the new LCD panel, some changes need to be made to the eIQ demos for i.MX RT1160/RT1170 otherwise you will just get a black or blank screen.
- Unzip the MCUXpresso SDK if not done so already
- Open an eIQ project
- Find the directory the eIQ project is located in by right clicking on the project name and select Utilities->Open directory browser here
- Copy both the fsl_hx8394.c and fsl_hx8394.h files found in \SDK_2_11_1_MIMXRT1170-EVK\components\video\display\hx8394\ into your eIQ project. You can place them in the video folder which would typically be located at C:\Users\username\Documents\MCUXpressoIDE_11.5.0_7232\workspace\eiq_demo_name\video
- Overwrite the eiq_display_conf.c and eiq_display_conf.h files in the eIQ project with the updated versions attached to this post. Typically these files would be located at C:\Users\username\Documents\MCUXpressoIDE_11.5.0_7232\workspace\eiq_demo_name\source\video
6. Compile the project as normal and the eIQ demo will now work with the new LCD panel for RT1160/RT1170.
