Need help with 16/14 segment led display code

The above is the code I'm using only added 4 more digits with a 2nd PPDB which had been damaged & now otherwise worthless.

The problem is 8 of 10 characters work as expected, however the 2 on the far right does not. They both display jarbled junk. On the program all I had changed is the paramaters for the pin set up from 6 to 10 on the two lines at the top. All other characters display correctly, so I know it's can't be a wiring issue. Can anyone help me on this?

    This is the problem. It seams to be combining characters into those 2 sections. I tried adding 12 characters, but get 4 char like that instead of 2. Maybe Steve Stuart the guy who wrote it could chime in? I tried moving the I/O pins around but no help. I'm at a loss here.

    So there's no body here who could possably help me with this? I've started looking over every single line of code, and so far can't find anything.

    Hi, Joe:

    I haven't looked at the 16-segment object, but I wrote the 7-segment object in the OBEX. Is it possible that the digit select pins aren't being controlled correctly? It looks like the segments on those last two characters are a union of all the segments from all the other characters. That would happen if those select pins were always low.

    It looks like it's doing that to me as well. I'll look at the code that's producing the display & check it out. Thanks.

    Well so far nothing there helped, I tried adjusting values in the 16 seg program & adusted the charaters, but not the screwed up ones. I'll keep looking though.

    After changing 3 byte variables to word ones in the PRI ShowSTR block. the screwed up parts vanished, however all the text looks alien now. H has been replaced with $, so if that helps someone figure out what I need to adjust here, cause I'm not sure what needs adjustment, cause I tried adjusting several values & not even remotely straightened out yet.

    Can you post your code and your wiring?

    I just tried the object you link to and it works fine.· I modified it for 10 digits without too much trouble.· It displays fine on the two PPDBs I have.

    Wonder why I'm having issues then? I'll redownload it, maybe it's been updated since I got it. I'll post it all alittle later, I gotta get it off of my laptop.

    Joe

    I just redownloaded it, my version is 1.3, I just got 1.4. I'll try it now.

    I just tried ver 1.4 & same problem. Checked my wiring, and I don't think that's the problem. I dropped the count to 8 & the display is fine.

    By what user name does Steve Stuart go by? I'll talk to him about this program & see if he can help since he wrote the program. I don't know what it is, but I can't figure out why my right 2 digits are stacking all the other characters togeather & displaying it on those 2 displays. I've continued using a different way for the moment using
    outa[noparse][[/noparse]9..0]:=%0000000000
outa[noparse][[/noparse]26..10]:=%00000000000000000
waitcnt(150_000+cnt)


    in a repeat loop setting each digit & the character in the outa sections. I've added a DAT area with all the letters & numbers already filled out, just using the ol variable bit to reduce program size. I've tried going through each section of the program Mr Stuart wrote & I can't seam to find the answer to my problem, so if he could pop up or if someone could tell me his board id it would be much appreciated. Thanks.

    Sorry I missed your original post, Joe. I don't make it to the forum every day. Your PM got my attention.

    I have made a change to the object and posted an update to the obex.
