tongenerator Posted October 21, 2008 Report Share Posted October 21, 2008 Hello,today i tried to install the displays on to the Core Unit.In first sight everything seems to be fine, MIDI is working and also the Displays light up. I have also double checked all pins are properly connected.so now, when i switch on the Core, i get continuously sysex Strings send to the Midi Out, which is probably right. so when i now start to upload of the mios operating system via midi, also everything seems to be done correctly as far as the mios studio application says...but as soon as the mios upload has been fulfilled, the display changes to the first picture, also still midi sysex is sent by core and the the displays seems to flash a little in the speed of syses is being sent.when i then switch off back on, nothing changes, but also for some reason i could recognize, sysexis no sent continuously anymore all the time. so what i mean is, it changes speed of sending messages.after i uploaded now also the sequenzer software, the display turns to the second picture and still sys ex is sent consant continuously without changes of speed.is there anything i am doing wrong? or does somebody know what the issue might be?thanks for any advisepicture 1:picture 2:edit:i have left the core switched on now in the current state. it just started to run a huge amountof sysex messages in very high speed and then stopped. now it is again sending sys ex in short instances again.

Are you using smart mode when uploading mios, and checking the wait for response box? Quote Link to comment Share on other sites More sharing options...
tongenerator Posted October 21, 2008 Author Report Share Posted October 21, 2008 now for some reason it seems right.i switch on the core an only one sysex message appeared, but the display is as the first pictureedit:fking hell...just when i finished writing the post the core started to send continuously sysex messages again ???and now it even changed between the two pictures. i need a cigarette ;Di have put the upload in to wait state and switched the core afterwards on, also i had used smart mode.

cimo Posted October 21, 2008 Report Share Posted October 21, 2008 seems like it goes on and off, can you check voltages at j1 and j2?can you tell us what you ve uploaded? Quote Link to comment Share on other sites More sharing options...
tongenerator Posted October 21, 2008 Author Report Share Posted October 21, 2008 hmmm ???actually i don't think that it goes on and off.if so, during uploading mios it should get of course interrupted and abort the upload,not give me upload success message. also the display back light should go on / of is well???i have just measured again the voltage is on j1 about 9 volt and on j2 around 4,96 voltsi have downloaded the mios_update_v1_9f.zip file and tryied to upload the mios_v1_9f_pic18f4620.hex file.as i mentioned, upload sucess, after on /off screen as picture and still sysex send... sometimes it starts to run thru fast...could it be there is something screwed up with the PIC oder Core Quote Link to comment Share on other sites More sharing options...
cimo Posted October 21, 2008 Report Share Posted October 21, 2008 .. puzzling, can you try to reupload MIOS, smart mode, wait for upload request. Quote Link to comment Share on other sites More sharing options...
tongenerator Posted October 21, 2008 Author Report Share Posted October 21, 2008 well, what do you think what it might be if nothing gives a positive result.i can upload mios in any way, i want. the core still keeps sending the messages.after switch on / off, first only one, then after a minute or so all the time...shall i get a burner and delete the core an reprogram it? or should i even think about building a new core with a clean pic?

tongenerator Posted October 21, 2008 Author Report Share Posted October 21, 2008 i found a relating thread, so i tryed now once again exactly like Mios Wiki.Switch on "display is like the 2nd Picture"Continuous sysex is sent by coreuploading mios 1,9 update.hexdisplay changed to the 1st picture, no more sysex messagesswitch off / on... only one sysex message appeared display like 1st pictureupload setup_mbseq_v3.hexcore again start to send continous sysex messages, display stays sameswitch off / on display changes to picture 2 and continuous syssex messages ???

cimo Posted October 21, 2008 Report Share Posted October 21, 2008 How can you be sure that MIOS is correctly uploaded?Have you checked the "wait for upload request" and used smart mode? (smart mode only for application upload)Can you upload an application while the core seems to be functional?Have you tried to disconnect the LCD?Have you checked 5 times every single component and every single point (with a multimeter for example)Simone shall i get a burner and delete the core an reprogram it? or should i even think aboutbuilding a new core with a clean pic?i would wait Quote Link to comment Share on other sites More sharing options...
tongenerator Posted October 21, 2008 Author Report Share Posted October 21, 2008 as far as mios wiki says. mios is installed properly when after switch on, only one sysex message appears...this is what happens when uploading mios...but then when uploading an application, for some reason the primary bootloader gets activated again.i had this problem allready before i even buy the displays... i thought there is something wrongwith the midi connection, because sometimes it wouldnt let me upload smething. i have made the holemidi troubleshoot 5 times... for fuck sak some reason now all midi is ok.i dont know, i realy spend lots of cash for the parts...i will build a complete new core and burn my own pic, hopefully it will work Quote Link to comment Share on other sites More sharing options...
cimo Posted October 22, 2008 Report Share Posted October 22, 2008 I don t want to sound arrogant or anything but what about answering at least some the questions i am making you? Sometime it is better to switch your head off and let somebody else doing the debugging for you (i ve learned at my own expenses)SimoneEDIT: maybe you can pass by the chat sometime, always packed with debuggers Quote Link to comment Share on other sites More sharing options...

tongenerator Posted October 22, 2008 Author Report Share Posted October 22, 2008 ;D sry, if i might sound a little harsh or what you would call it in englisch..., but i realy start to get headache...i never thought to run into so many problems. one by another. at least now i understand the schematics of the core@topic:i am now sure MIOS is running :-Xfor some reason still it screws everything up when uploading the sequencer software,but for now i dont even want to know why that is ::). but for a fact, other applications are running,so mios has to be ok. i installed for exampel midi benchmark, ok. it ran nice.. i could see it working :)but the display is not working like it schould do. i installed the lcdinterconnection.hex it semmeslike id did something to the display, but not realy schowing anything, exept of the display of the1st picture i post earlier, maybe sometimes a little flickering. however i have checked at least 5 times that the pins are properly connected. at the paper i downloadedfrom the web about my display it says as picture that here is pin1 and at the other side pin2. if so, it mustbe pin7 starting for d0 above the pin1???i can also adjust contrast and brightness by the trimpots, so i guess i did the proper pin connections...i just don't get a clue out of the hole story. i just see, that with every problem i get, i create new problemswhich have to get fixed. well, mios is running.could it be that my displays wont work with the core at all because there are not compatbile?it says it is KS0066 or Equivalent??? As far as i heard it schould be compatible? Quote Link to comment Share on other sites More sharing options...
tongenerator Posted October 22, 2008 Author Report Share Posted October 22, 2008 if somebody out on this planet is reading this???maybe i have found another question.is it correct to have 4,97 volts on Pin 33 of the PIC (D0) ?on pin 33 i have +5V on all other data pins +0V, but -5VRS is having 0,08V all other pins nothing except of +5V on E and Vä Quote Link to comment Share on other sites More sharing options...
stryd_one Posted October 23, 2008 Report Share Posted October 23, 2008 I assume that you're testing it with the PIC off or better yet removed.... But no, that's not normal. You've shorted something there... Quote Link to comment Share on other sites More sharing options...
tongenerator Posted October 23, 2008 Author Report Share Posted October 23, 2008 no, i messured with the pic on.when i take the pic of i dont have any voltage on this pin.when i put it on, i hve +5 volts on pin33, all other data pinshave nothing.

stryd_one Posted October 23, 2008 Report Share Posted October 23, 2008 Is this a 4620?Did you use smart mode? Wait for upload request?Did you burn the bootloader or is it from smash? If it was you, please burn it again, and paste logs.Upload MIOS again, and then a test app. Paste the logs here. If it is not working, do the midi troubleshooting, and paste the logs here.

tongenerator Posted October 23, 2008 Author Report Share Posted October 23, 2008 now it works with the display ::)yesterday i realy started to think about what it might be andstartet to unsolder everything near the J15 and cleaned everything to make sure there are no shorts.but i thought not about trying it once again.so now i was realy wondering why the upload did work properly and the appliction is running as it schould.now i again beeing realy carefull by soldering the wires into J15 (i solderd the wires directly on to the boardwithout the pins)and it fucking works now ???i had to many problems to solve, one by one and with every problem i found i fucked up something else... :-Xoh dear, at least i learned something this way. and i am realy surprised about how robust it al is, because when i think about how much i messed around it realy is a wonder nothing is realy damaged.
