nILS Posted June 12, 2008 Report Share Posted June 12, 2008 Upgrade to 1.9f, try again, tell us what's up ;-) Quote Link to comment Share on other sites More sharing options...
/tilted/ Posted June 13, 2008 Report Share Posted June 13, 2008 ? do i need a special driver for this one ? I can't remember where i bought it.No, you don't need a special driver.according to the datasheet it uses the Hitachi controller.I would be quick to jump to a wiring error as a conclusion. In each of the characters shown on screen in the photo, the d2 line is set high, and the d7 is set low.

stryd_one Posted June 13, 2008 Report Share Posted June 13, 2008 Heh, I saw that too, but then I realised - the cursor has been set correctly, so I wasn't so sure...Edit: Maybe the RS line is shorted to those two pins? Quote Link to comment Share on other sites More sharing options...

vix Posted June 18, 2008 Author Report Share Posted June 18, 2008 so... i updated to 1.9f and after rebooting the lcd shows me several martians screens then stop on this one :nice isn't it ?i checked my solderings one morrrre time.. nothing (it's simple because at this step i have only the core, the obpl3 and one DIN4 with nothing connected to it, and the LCD)by the way these are readymade midibox.org boardsso this is for sure lcd wiring, thanks tilted !but as this lcd have not "in line" pins, i'm a little confused with the numbers :there are 2 vertical columns of 8 pins :the up-right one is #16and the down-left one is #1but what is the down-right pin ? #2 or #8 ???i think i wired it thinking it was #2 Quote Link to comment Share on other sites More sharing options...
vix Posted June 18, 2008 Author Report Share Posted June 18, 2008 i've seen on the data sheet that i was right, the down-right pin is #2 (seen from the back, oposite to the datasheet drawing)so now... i'm resoldering all the lcd wiring....i'll tell you what happened soon :P Quote Link to comment Share on other sites More sharing options...
vix Posted June 18, 2008 Author Report Share Posted June 18, 2008 so i made a new wiring for the lcd, paying attention very carefully to pin numbersand the result is exactly the same !!i checked with a small 2x16 testing lcd i made, the MBFM works, the display is oki noticed i got a short on the J15 of core module between pin V0 (named VL on the lcd datasheet) and pin Vssis it normal ?thanks guys Quote Link to comment Share on other sites More sharing options...
vix Posted June 18, 2008 Author Report Share Posted June 18, 2008 ok it works now !!! ;Di guess it was my connector, one D# pin was not connected...thanks for your support guys ! Quote Link to comment Share on other sites More sharing options...

vix Posted June 19, 2008 Author Report Share Posted June 19, 2008 i didn't use your table to find the pin (more simple to do a continuity test)but of course it helped ! thanks for your accuracy, i hope u'll see my future troubleshooting posts ;D Quote Link to comment Share on other sites More sharing options...
/tilted/ Posted June 21, 2008 Report Share Posted June 21, 2008 Did you pass my message on?Did it help?i didn't use your table to find the pin (more simple to do a continuity test)Actually vix, I meant my other message...http://www.youtube.com/watch?v=6cid85WBkvcGlad to hear it's working... ;D Quote Link to comment Share on other sites More sharing options...

nILS Posted June 21, 2008 Report Share Posted June 21, 2008 If Martians speak in white noise, then my mbFM kinda speaks martian at times. Quote Link to comment Share on other sites More sharing options...
