That's work good.</P><P>My lcd is ampire AM-800480L with the same resolution but the size is bigger, that's display well.</P><P>Both of them have the touch panel with 4 line connect to imx53.</P><P>I use the seiko driver to control ampire.I can touch the panel of ampire but the imx not get right position ( error about 2-3mm, I just measure by my eye).</P><P>I don't familliar with os system, that's I can't understand how it works.</P><P>My question is:</P><P>- I want to debug the position when I touch to the panel of LCD.</P><P>What file I need to modify to printf the x-y position to visual 2008 (in debug mode)?</P><P>After that I want to modify to make imx53 understand right position.</P><P>- If possible, can you explain what OS system work? Does it like the microcontroller work in file main.c and if interrupt happen that jump to interrupt function?</P><P>Thanks in advance.</P></BODY></HTML> Thu, 29 Mar 2012 04:44:21 GMT HaiDangSon 2012-03-29T04:44:21Z Touch control? https://community.nxp.com/t5/i-MX-Processors/Touch-control/m-p/149507#M780 <HTML><HEAD></HEAD><BODY><P>Hi every one.</P><P>I have some trouble about the touch lcd.</P><P>The freescale's lcd is seiko&nbsp;43WVFIG.
