A TFT LCD is also connected to the LCD interface.</P><P></P><P>After sending out the gerber file to the PCB manufacturer, I found a mistake about the LCD interface.</P><P></P><P>I have wrongly connected the LCD's R[7:0], G[7:0], B[7:0] to the CPU's R[0:7], G[0:7], B[0:7].</P><P></P><P>I know that some CPU sends configuration via the RGB data bus, some others only sends RGB color data via the RGB bus.</P><P></P><P>I have little knowledge about the I.MX6 Ultralite CPU LCD interface. Would it send only color data via this BUS? If so, then my board would still be used a development board with wrong color displayed on it. Otherwise, the LCD will not display anything meaningful.</P><P></P><P>Anyone could give me a hint?</P><P></P><P>Thanks.</P></BODY></HTML> Thu, 17 Dec 2015 06:43:46 GMT https://community.nxp.com/t5/i-MX-Processors/A-Question-about-the-I-MX6UltraLite-LCD-Interface/m-p/489164#M78402 zongruzhan 2015-12-17T06:43:46Z https://community.nxp.com/t5/i-MX-Processors/A-Question-about-the-I-MX6UltraLite-LCD-Interface/m-p/489165#M78403 <HTML><HEAD></HEAD><BODY><P>Hi Zongru</P><P></P><P>I am afraid bit reordering is not supported, so you will see wrong colors.</P><P>Byte swapping is supported and it is described in</P><P>sect.33.4.2 Write Data Path i.MX6UL Reference Manual (rev.0&nbsp; 8/2015)</P><P><A class="jive-link-external-small" href="http://cache.freescale.com/files/32bit/doc/ref_manual/IMX6ULRM.pdf" rel="nofollow">http://cache.freescale.com/files/32bit/doc/ref_manual/IMX6ULRM.pdf</A></P><P></P><P>Best regards</P><P>igor</P><P>-----------------------------------------------------------------------------------------------------------------------</P><P>Note: If this post answers your question, please click the Correct Answer button.
