shobley Posted September 3, 2007 Report Posted September 3, 2007 I just connected everything up and I got this in SysExBox..."Received SysEx Block from Device 3F with 8 bytes in MIOS format - cmd 01 (not saved)"at a regular interval...Does that mean my core module is working OK?? :DSteve Quote
abcmann Posted September 3, 2007 Report Posted September 3, 2007 You see your upload request :). but it says only that your midistrain is working atm. there CAN still be errors in other sections of the pcb!congratulations :) Quote
shobley Posted September 4, 2007 Author Report Posted September 4, 2007 OK as far as I can tell the Core module is working. I uploaded MIOS 1.9f and MidiBox64 and it worked OK with all the checksums intact.I just finished wiring up an LCD and I just get the block pattern on the top row. The contrast/brightness work OK, but no messages.Any ideas on what could be wrong?I've checked my pins and they seem to be OK. Quote
midiboxxer Posted September 4, 2007 Report Posted September 4, 2007 Please check the cabel a second time, what kind of LCD do you ue (size, controller...)?GreetingsMarkus Quote
stryd_one Posted September 4, 2007 Report Posted September 4, 2007 OK as far as I can tell the Core module is working. I uploaded MIOS 1.9f and MidiBox64 and it worked OK with all the checksums intact.I just finished wiring up an LCD and I just get the block pattern on the top row. The contrast/brightness work OK, but no messages.Sounds like the bootloader is starting, but not MIOS. Did you use MIOS studio in smart upload mode? (You should!)What do you recieve on your midi interface at this point? Quote
shobley Posted September 4, 2007 Author Report Posted September 4, 2007 I checked the wiring on the cable - I am using the standard 2x20 VK2220 module. Conductivity is good, and all the pins are wired correctly. I do have a rev3 board but I took the jumper pins from the latest rev documentation. The brightness/contrast dials work OK so I assume I have these the right way round.The midibox seems to work - I have uploaded MIOS without error, and the Midibox64 application and all the checksums are OK. I did have an issue originally when I uploaded the wrong hex file. Now when I start the board I get a single request to upload, and then a whole bunch of messages (blue in MIOS studio) from the Midibox64 app - basically a set of controller data. I have not wired up the AIN or DIN module yet - but I don't think this would stop the display from working.Not sure what else to do... Quote
stryd_one Posted September 4, 2007 Report Posted September 4, 2007 I do have a rev3 board but I took the jumper pins from the latest rev documentation. I would check the doco for your revisionThe midibox seems to workYou think? ;D I'll just stop helping then. heeheheheI have uploaded MIOS without errorAsking again.. did you use smart mode?I did have an issue originally when I uploaded the wrong hex file. What were the issue, the file, and the solution?Now when I start the board I get a single request to upload, and then a whole bunch of messages (blue in MIOS studio) from the Midibox64 app - basically a set of controller data. Fell free to paste it... and don't forgetI have not wired up the AIN or DIN module yet - but I don't think this would stop the display from working.auaimbctgNot sure what else to do...Hang in there...

shobley Posted September 4, 2007 Author Report Posted September 4, 2007 Sorry - yes I did use smartmode, after each block I get the checksum OK response.I will post the output, as soon as I can work out how to cut and paste. Quote
shobley Posted September 4, 2007 Author Report Posted September 4, 2007 I don't seem to be able to find the pinout for a Rev3 board. :(Actually one thing I do find confusing about the docs I have read is that there is no orientation information on the pin assignments, jumpers can go on 2 ways y'know...

shobley Posted September 4, 2007 Author Report Posted September 4, 2007 Issue with uploaded the wrong version was...[From memory]Checksum OK...Checksum OK......Write Error...(This error was expected)Write Error......Aborting after 16 errorsUploading the correct file...Checksum OK......Upload successful.

cimo Posted September 4, 2007 Report Posted September 4, 2007 hiI have not wired up the AIN or DIN module yet - but I don't think this would stop the display from working.in my MBLC in OSX with MIOS Studio the LCD gets stuck and even Mios studio and the whole system hang if i don t ground the AINs when they are activated in the application...Simone Quote
Echopraxia Posted October 2, 2007 Report Posted October 2, 2007 I am having a similar problem with the 2x40 lcd. I am only getting black bars on the top row and nothing on the bottom row.The blacklight is working just fine and I adjusted both trim pots on the core aswell. Is this normal? I don't have the ICs in place on the core yet (still testing). Do I need to put the ICs in and load MIOS to get the second line to show? Quote
TK. Posted October 2, 2007 Report Posted October 2, 2007 Do I need to put the ICs in and load MIOS to get the second line to show?yes, exactly: so long MIOS hasn't been booted, your LCD isn't initialised. Also the black bar is normal, see this oversight:(steps must be read from bottom to top)Best Regards, Thorsten. Quote
Echopraxia Posted October 3, 2007 Report Posted October 3, 2007 Thanks TK. I got it to work just fine! My sequencer is up and running. I typed in 64k for the banksticks in the asm and I think thats all you noramlly need to do right? Now I just need to get my encoders and switches so I can actually do something with it. Quote
