I think the PIC ID is right: Thanks, mischa

YAY now it works fine! Seems that something in the GLCD detection didn't work for me..?

Hello! The MIOS i've used was always the unchanged one - File pic18f452/midi/mios_v1_9f_pic18f452.hex I have uploaded MIOS and the LC App again from a newly extracted package - same result. It really eems I have a hardware problem somewhere, but why does the test app work then... ???

@ cimo: okay, no problem :) Yep I tried all that, changed LCD_USE_SECOND and the INITIAL_DISPLAY_PAGE, but i still see a similar screen. But I remember when I uploaded the LC App 2 years ago with only one display connected, I saw a quite "graphical" Screen that used fonts etc. I don't really know what else to change in the LC Code

Nope, it looks like this:

Hello! now both of my displays seem to work properly, so I uploaded the LC Application. Now it looks like the LC App still thinks I have character LCDs connected. I have already set the PIC ID header to 0000000000001000 with the change ID application. Do i need some changes in the LC source Code? I have played with these values and the screen changes accordingly, but I never get a "graphical" screen. #define LCD_USE_SECOND 0 ; the emulation handles with two character LCDs if 1 #define LCD_EMU_COL 55 ; number of emulated columns (characters per line) ; o graphical LCDs: use 55 (like a Logic Control) ; o one 2x40 LCD: use 40 (unfortunately..) ; o two 2x40 LCDs: use 55 (like a Logic Control) #define INITIAL_DISPLAY_PAGE 0 ; initial display page after startup (choose your favourite one: 0-3) What have i forgotten? Thanks! redagrds, mischa

Thorsten you are a genious! You where right with CS3... When i labeled my plugs I misinterpreted the board layout thinking that J8 was the "row" on the bottom because it's written J9/J8......well i should have rechecked that too, not only my soldering! but now i plugged it in the other way round and.. I even managed to move everything in the center and the knobs far to the right (having a 256x64 instead of a 240x64) --> my first efforts in "coding" MIOS applications, yay :D tomorrow Im gonna continue with the LC App, thanks for your help! Regards, mischa

Okay thank you! I'll swap the CS lines from display 1 and 2 to see if this is the error. I will let you knwo the results! Thanks & regards, mischa EDIT: Yep, you were right, same result with swapped displays....guess I'll have to recheck my wiring......

when i put it "non inverted" and the new app_lcd.inc, its the same result as in the start (this: )

Yes Im able to assemble .hex files... I changed the app_lcd.inc file, but now I have got a nearly blank left screen with some half buttons on it, the right screen remains nearly the same... again, thanks for helping me out!

Thanks thorsten! ....but I fear the inverted CS lines are not the problem......now my screens look like this: far too many knows on the screen i think >:( @cimo: sorry, the images are uploaded to the webspace of my university, maybe the blocked some IPs or something....I will upload them elsewhere as soon as possible! regards, mischa

hi! thanks you for answering! I have found this thread but I do think i have the newest version of MIOS, on my Screen it says 1.9f while booting (as seen on the picture in the first post) I do think i have tho change the code somewhere, but I have no idea where to look..... thanks! mischa

Can you tell me where to do that? As I said, I'm not yet familiar with the MIOS coding. :-[ thank you! mischa

Ok, now I uploaded the LC App (just for testing, without any source code changes) Now the result looks like this: (I don't know yet much about Midibox coding, but I'm working on it 8)) Seems to be quite a mess....as far as I know, the startup screen should spread over both screens, am I right? Anyone now whats wrong? Also, it seems that the most right 16 pixel column is unused (like I have found in other threads), but i think I will take care of this later... Thanks for your help! Mischa

Hello! After a 2 year pause, I've just finished the core module and connected the first lcd. Being quite a newbie to the work with microcontrollers, I was surprised that everyhing worked perfectly. I updated MIOS and changed the PIC ID (graphical LCD). Everything worked, the display reads "READY." Then I connected the second LCD, and surprisingly it nearly also worked. Only there seems to be something wrong with some offset or something similar. It looks like this: (while booting) On the right display, some characters seem to have "moved over" a little. But after that, "READY." is written on both displays correctly. Do I have to change something in the MIOS; can you help me? Or am I completely mistaken and my wiring is bad somewhere? Thanks for your response! Regards from Austria, Mischa
