Thanx for the reply Justin. Yeah, I only have 48 pots right now, and have tied the extra 16 inputs to ground. I will try your suggestion and tie the channel select inputs on the Core to ground and see if that solves my jitter problem. (only happens on the Edit Pot Names and Edit Events pages, everything else seems to display and function correctly). I have a couple of hundred 10K pots on order and should be able to finish my pot board in a week or so. Have a GREAT DAY!!! gb

Hey Guys!! Well I did finally get the '452 core to function. But I still have a few problems. the major problem is... when I go to the 'Edit Events' page, the lcd is erratic. The cursor will not stay on the selection to change and only goes to the first and second positions on the bottom row. I can't get it to change the pot number, or if it is.. the lcd is scanning so fast I can not see where the cursor is. Any ideas? thanx in advance, gb

WOOOOHOOOOO!!!!! it was the opto-isolator! loaded the main.syx... now getting MIOS version and 'hello world' !!! let's see if I can get any farther along the path to enlightenment. thanx for all the help! gb

I have included a link to a picture of my MidiOX screen. can anybody tell anything about what this says? http://www.ggbnet.com/midibox-midiox-capture-a.GIF thanx in advance gb

Well, there are times when I can really be dense, and this appears to be one of those times. I never set MidiOX to display HEX.... duhhh. did that and at least the core is sending the (F0 XX XX XX XX) request to send string to MidiOX, so I am assuming the core is doing what it's supposed to. I am beginning to think my midi-in to the core may be disfunctional in some way. I will test that today. Moebius, I was under the impression that TK had posted all of the (already converted) .syx files to the website, so I have been using those. Do I really need to run the perl scripts against the original hex files and use those instead? Thanx for the help!! Have a GREAT DAY!!!!! gb

>> Then convert MIOS and Applications from HEX to sysex with hex2syx.pl using -device_id [id] for each core. this part has NOT occured!!! will try it when I get home tonight!!!!! THANX Moebius!!!! will keep my fingers crossed. gb

thanx for the reply DOC, yeah, that's the procedure I have followed.... still get the same SYSX message as stated in my original post and the lcd displays all blocks on the top row (forgot to mention that yesterday). When same board is stuffed with a `877 DINX4, lcd, pots, buttons all work fine. Of course, I have only had a couple of hours a day to play with this since getting the `452, so will have a bit more time this weekend to dig deeper. Have a GREAT DAY!!!! thanx gb

yeah, I changed the bankstick lead to pin 28 (RD5) I don't use a SID and only have one DIOX4, with nothing else attached to SC. however, I have had a hard time getting my head around the ID of the chip. when I bring up IC-Prog and load the bootloader, the ID appears to already be set to 000000000 (however many zeros it is) I will want to use this in a multi midibox config eventually. Am I still missing something? thanx gb

I have been using my midibox based on the 16f877 for a while. Now I am attempting to start with MIOS. I have made the hardware mods to the JDM programmer. swapped the 20MHz xtal for a 10MHz xtal and added the extra 10k resistor to fix LVP. When I plug power into the core module....MidiOX shows: SYSX: 240 0 0 126 64 0 1 247 I have no idea what this means. I am using a standard 2 x 16 lcd , one DINX4, one AIN(32 pots), and one keypad plugged into the DINX4. All of this stuff works with the '877 version/chip Any help whould be greatly appreciated. thanx in advance :) gb
