leelinn Posted February 22, 2005 Report Share Posted February 22, 2005 Hiis it possible to use a 4x20 LCD blue with backlit? I find one to a very low price.Just a little curiosity: does lcd show only words in midibox sdi? or does it show any graphic? Quote Link to comment Share on other sites More sharing options...
TK. Posted February 22, 2005 Report Share Posted February 22, 2005 No, it doesn't show any graphic, it's already (very) hard enough to bring all the code into the small flash ;-)A 4x20 should work, it allows you to display up to 10 items at once, but you've possibly to do some modifications in the display layout (never tried this...)Best Regards, Thorsten.

nILS Posted February 22, 2005 Report Share Posted February 22, 2005 If I'm not mistaken, the 2 bottom lines are displayed as if it was a 40x2 display. At least that's what my test LCD did =) So, it should display 5 items in the top 2 lines and 5 in the lower 2 without any code changes.nILS Quote Link to comment Share on other sites More sharing options...

If so, I would love to do that and put buttons across the top and bottom, like this:* * * * *------------| |------------* * * * *Can anyone confirm if that is how it works? And..do you have any tips or reasons why my idea wouldn't work? Quote Link to comment Share on other sites More sharing options...
moebius Posted February 24, 2005 Report Share Posted February 24, 2005 Sorry,Can't confirm, but that's how 4*20 HD44780 displays are supposed to do. :DBYe, Moebius Quote Link to comment Share on other sites More sharing options...
Julian Posted February 26, 2005 Report Share Posted February 26, 2005 I can confirm this!I had a 4x20 as test display on my MBSEQ...best,julian Quote Link to comment Share on other sites More sharing options...
Lo-Fi_Massahkah Posted March 13, 2005 Report Share Posted March 13, 2005 So what would happen if I put a 4x40 on the SEQ2 instead af the double 2x40. Anyone have the answer?Regards,Mikael Quote Link to comment Share on other sites More sharing options...
TK. Posted March 13, 2005 Report Share Posted March 13, 2005 A 4x40 LCD has two independent data ports (or at least two independent enable lines), it behaves like two 2x40 LCDsBest Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Lo-Fi_Massahkah Posted March 13, 2005 Report Share Posted March 13, 2005 Thanks Thorsten - you're quick!So that would mean that I could replace the 2 LCDs with one, for the SEQ project...?Cheers,Mikael Quote Link to comment Share on other sites More sharing options...
TK. Posted March 13, 2005 Report Share Posted March 13, 2005 Hi Mikael,you could - but when you are asking me, I would never replace two 2x40 by a single 4x40, the usage with two 2x40 is much better!!!Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Lo-Fi_Massahkah Posted March 13, 2005 Report Share Posted March 13, 2005 Thorsten,Are there any ergonomics that I'm not considering, except for the fact that it won't be alligned with the pots and buttons?Thanks,Mikael Quote Link to comment Share on other sites More sharing options...
TK. Posted March 13, 2005 Report Share Posted March 13, 2005 Hi Mikael,also the position of the LED wouldn't be correct. Just the whole usage wouldn't be so perfect like with two 2x40 displaysBest Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Lo-Fi_Massahkah Posted March 13, 2005 Report Share Posted March 13, 2005 Allright! ;D I'm convinced!Thanks for your time./Mikael Quote Link to comment Share on other sites More sharing options...
