You can adjust the display registry settings directly using the iMX6 Display Tool. The tool provides an interactive graphical interface with all the display settings supported by the display driver through registry. Previously, we used this functionality as a part of our Colibri Tweak tool, but for better maintainability, we have now split it into a separate display tool for the iMX6 modules only.
The features are further subdivided into specific configurations to provide a better understanding of the tool.
BPP Specify the bit per pixel which is used in the internal frame buffer. LDDS Specify the number of data lines which are used to connect the display. Out Select the display output channel for Apalis iMX6D/Q modules only. hsp Polarity of the Hsync signal. vsp Polarity of the Vsync signal. pcp Polarity of the pixel clock signal.
Pixel Clock(pclk) Configure the pixel clock frequency. hsw Horizontal Sync Width. Sync setup time in clocks. blw Beginning of Line/Beginning of Frame Pixel Clock Wait Count. (Back Porch in clocks. Yes, our "front" is the back porch). CxScreen Here you can set the horizontal resolution of your display. elw End of line width. Sync setup time in clocks. vsw Vertical sync width. bfw Beginning of frame width (Back Porch). CyScreen Here you can set the vertical resolution of your display. efw End of frame width.
VideoMemSize Allocated memory for display driver in Bytes. BL_GPIO GPIO Used to turn ON/Off Backlight. BL_POL Polarity for Backlight GPIO. DISP_GPIO GPIO used to turn ON/OFF display. DISP_GPIO Polarity for DISP GPIO. UseSplashSettings Uses the configuration used for the splash screen. Rotate Rotate display to according to the requirement.
SavePreset Save the current display settings to a .reg file. Preset Here you can choose a display preset. The display preset files have to be in a folder called "DisplayPresets" which is on the same place as the iMX6_Display_V1.1_WEC7.exe or iMX6_Display_V1.1_WEC2013.exe. Save Save the display settings to the Registry and save the registry to the flash memory.
