protofuse Posted March 22, 2010 Report Share Posted March 22, 2010 hello, I'd like to know your opinion about the compatibility of this LCD with the midibox CORE8 http://www.crystalfontz.com/product/CFAH2002ATMIJT.html I have one. I made a mistake when I first connected it... I probably killed it :-( but not sure backlight is ok (but I guess it is a basic led) even the MIOS version message doesn't appear sometime, I have characters filled a bit it isn't stable etc. so I'd like to know if the compatibility (protocol & power supply) was ok & if there was some tests to do before drop it all the best!CFAH2002ATMIJP-3.pdf Quote Link to comment Share on other sites More sharing options...
philetaylor Posted March 22, 2010 Report Share Posted March 22, 2010 (edited) Hi. It looks to use a standard HD44780 or equivalent controller so should definately be supported by MIOS8. What app did you have loaded on the core? Is it definately compiled defaulting to the clcd driver??? Most LCD problems are related to wiring, so I would double and triple check it, also what PIC are you using? The PIC18F4685 for example only supports 4-bit LCD connections. What mistake did you make when you connected it? Was there smoke ? Cheers Phil Edited March 22, 2010 by philetaylor Quote Link to comment Share on other sites More sharing options...

Cheers Phil hello phil! the app is a basic one and based on MB64: http://svnmios.midibox.org/filedetails.php?repname=svn.mios&path=%2Ftrunk%2Fapps%2Fcontrollers%2Fprotodeck_v1%2Fprotodeck_CORE_2%2Fmain.c I'm using a PIC18F4620. the LCD was VERY hot (the chip inside the black plastic under the lcd especially) when I plugged it bad! no smoke (!)

philetaylor Posted March 22, 2010 Report Share Posted March 22, 2010 the LCD was VERY hot (the chip inside the black plastic under the lcd especially) when I plugged it bad! That doesn't sound good.... If you are not even getting the MIOS welcome screen then unless there is a wiring error, it does look like the display is toast.....
