I'm working with RGB 16bit mode 565.</SPAN><BR /><BR /><SPAN>I fill SDRAM with 0x1F which should be pure blue then configure framebuffer to point to 0x1C000000.</SPAN><BR /><BR /><SPAN>The problem I see is that after everything is set, display is only noise with several colors. I checked with scope and I do see some pulses on Red and Green lines which is not expected since framebuffer has only blue info.</SPAN><BR /><BR /><SPAN>Can anyone see what I'm missing?</SPAN><BR /><BR /><SPAN>Thanks!</SPAN></BODY></HTML> Wed, 15 Jun 2016 18:23:46 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LCD-controller-outputting-something-different-than-framebuffer/m-p/540025#M11984 lpcware 2016-06-15T18:23:46Z Re: LCD controller outputting something different than framebuffer content https://community.nxp.com/t5/LPC-Microcontrollers/LCD-controller-outputting-something-different-than-framebuffer/m-p/540026#M11985 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by egnascimento on Fri Nov 27 06:19:22 MST 2015</STRONG><BR /><SPAN>Anyone?
