d2k Posted October 1, 2003 Report Share Posted October 1, 2003 Hey...I've added 3 internal banksticks to my SID CS box, but I still want the option for an ext bankstick...Should the 9pin plug (and subsequant ext banksticks) be connected like the forth eeprom in this image: http://www.ucapps.de/mbhp/mbhp_multi_bankstick.gif or do i just connect as before - straight to J4 on core and keep everything wired like this: http://www.ucapps.de/mbhp/mbhp_bankstick.gifI guess either way will work, but the later option would mean when an ext bankstick is plugged in it'd replace the 1st internal bankstick right?BestDan Quote Link to comment Share on other sites More sharing options...
pay_c Posted October 1, 2003 Report Share Posted October 1, 2003 I think the 1st way is the one to go. You will handle the bankstick as a fourth one. Easy.The other solution (just put it parallel there if I understood you) will certainly bring up problems! You have 2 banksticks in *parallel* which is absolutely not good. I would say this wont work at all. Quote Link to comment Share on other sites More sharing options...
TK. Posted October 2, 2003 Report Share Posted October 2, 2003 The wiring doesn't matter (so long as vss, ground, SCL and SDA are connected together in parallel), it's only important that every BankStick in the IIC network has its unique address.Best Regards, Thorsten.

pay_c Posted October 2, 2003 Report Share Posted October 2, 2003 Yeah, that´s what I meant said much more shortly! ;D Quote Link to comment Share on other sites More sharing options...
d2k Posted October 13, 2003 Author Report Share Posted October 13, 2003 Is is possible to select a diff bankstick from the 3 I have connected via a sysex/midi msg?* Reason being - I no longer have a control surface, since I decided to make proper pcb's for the button/led/encoder brds cos I was sick of troubleshooting amongst a mass of wiring...so i ripped it all out in frustration, but the new brds aint done yet...BestDan*Same goes for selecting each SID, setting LINK mode etc...

TK. Posted October 14, 2003 Report Share Posted October 14, 2003 Hi Dan,the BankStick select feature has not been integrated into the application yet, just wait for the next release. I don't see a reason why you would like to select a SID without the control surface?Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
d2k Posted October 15, 2003 Author Report Share Posted October 15, 2003 the BankStick select feature has not been integrated into the application yet, just wait for the next release.great. i'm guessing a few buttons to select each bank would also be possible...? I don't see a reason why you would like to select a SID without the control surface?well, so i can load/edit diff patches on each SID seperately. However, I can't do anything now as I cant get the SID app to load at all :(. I was using the 18F in another core to test some 2x40s LCDs. When putting it back in the now controller-less SID box and loading the SID app back on I keep gettin endless 'Formatting Bank' loops on the LCD...tho there's no banksticks connected. I tried Mios 1.4/with lastest SID rls - tho i did test prior ones too, same deal - the only version that loaded correctly was when i used mios 1.3 with a old sid 1.4 f/w rls...BestDan Quote Link to comment Share on other sites More sharing options...
TK. Posted October 18, 2003 Report Share Posted October 18, 2003 Did you stuff the 1k pull-up at pin RA4?Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
d2k Posted October 18, 2003 Author Report Share Posted October 18, 2003 Hey T...Yes, all brds have been working (this is the original quadsid box i had goin....so 1k resistor is stuffed...and cheks ok...BestDan Quote Link to comment Share on other sites More sharing options...
TK. Posted October 18, 2003 Report Share Posted October 18, 2003 Could you please check it with a connected BankStick, just to give me more input?Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
d2k Posted October 18, 2003 Author Report Share Posted October 18, 2003 Doesn't make a diff when a bankstick is connected - same deal...turn on, says loading setup from bankstick, then proceeds to format the bankstick in a continous loop...Just to clear - this happens regardless if a banksick is connected or not Quote Link to comment Share on other sites More sharing options...
TK. Posted October 18, 2003 Report Share Posted October 18, 2003 Very strange - the problem must be hardware related, because I didn't notice such bankstick problems on any MIOS core.Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
d2k Posted October 18, 2003 Author Report Share Posted October 18, 2003 well, that cleared that up then :(...any ideas what 'hardware' would cause this? I dont - and it was working fine before...CheersDanBTW: If it was a h/w prob as u say - why would mios 1.3 with the midibox_sid_v1_4_18f_stepB f/w load up okay?When i use this, it just does the formating bank bit at boot once, then goes to the main SID o/s screen. Yet with mios 1.4 and any 1.5 sid rls it's not, but was before? what a shitter....another box in bits Quote Link to comment Share on other sites More sharing options...
TK. Posted October 18, 2003 Report Share Posted October 18, 2003 I'm not sure why it does only work with MIOS V1.3 at your board, either you are not using the original MIOS and SID releases (download them again, ensure that MIOS V1.4 is correctly uploaded by using the CRC test), or MIOS V1.4 is more sensible to a hardware error. There is only one reason for an endless reformat: if the 1k pull-up at RA4 is not connected, regardless if a BankStick is available or not this is a *must*. You could measure the voltage at this resistor just to ensure that the +5V are there.You could also try another application which uses a BankStick like the bs_xfer example to ensure that MIOS can access your bankstick.Best Regards, thorsten.

d2k Posted October 18, 2003 Author Report Share Posted October 18, 2003 Scratch all that...:DNew PIC sorted it...!SO, are 18F's prone to failures or is just a freak event? Quote Link to comment Share on other sites More sharing options...
smashtv Posted October 18, 2003 Report Share Posted October 18, 2003 SO, are 18F's prone to failures or is just a freak event?Heya D2!I guess I'll speak up here, since I have probably handled more 18F's than anyone around here.... ;)I do know that quality control on the 18F's is a bit lacking, I have had 5 or so that were bad out of the tube (out of 100+ that I have handled) and each batch seems to have it's own personality. Some will program without issues on a stock JDM, some need the extra 10k resistor on the JDM, and some require that they be erased before they will program.They are extremely sensitive to static when handling only the bare chip, and for some reason seem to be more so before they are programmed. (that might just be coincidence, not sure yet)That said, I put the static wrist strap on and keep it on, from the time I pull the tube, through programming, until I seal it in it's short tube and anti-stat bag.Luckily the vendor I am using for the 18f's now is pulling from a stock of 3000+ 18f's that they have on hand, so I don't have to figure out the "attitude" of each batch as they come in. :)Have fun!SmashTV Quote Link to comment Share on other sites More sharing options...
d2k Posted October 18, 2003 Author Report Share Posted October 18, 2003 Well, mebbe i spoke too soon...:/Although, all sids seems to working, and the banksticks are all good - i'm getting a very nasty high pitched whine after a play a few notes into the SID...Here's what she sounds like:http://notapplicable.co.uk/mbhp/sidwhine.mp3Again, i'm not sure of the prob...*EDIT*went back to the prior rls (midibox_sid_v1_5b_18f_stepC - working fine and with no whine! :)CheersDan Quote Link to comment Share on other sites More sharing options...
TK. Posted October 21, 2003 Report Share Posted October 21, 2003 SmashTV: I noticed the same, some PIC18F are working fine with an unmodified JDM, some others require an additional external power supply for programming, even if they are from the same batch.But the 10k resistor is required anyhow. After production the so called low voltage programming mode is enabled by default, it has to be disabled with the 10k pull-down. If pin RB5 is floating, you've a 50:50 chance that the programming procedure will pass (depends on supply voltage, ambience temperature, etc...). Once you've programmed the PIC, the LVP is disabled and therefore the programming will also work w/o the 10k pull-down.Dan: could you please try the most recent version again - I don't believe that the small changes made in the update are the reason. If you hear this sound again, create a backup of your system like described here:http://www.ucapps.de/mios/mios_backup.txtand send me the files so that I'm able to "clone" your setupBest Regards, Thorsten.
