I have attached my modified version of the ROBOLYMPIC code. 

Jon - I hope we can call a truce as I certainly didn't mean to upset you. You and others from Parallax, incl Bean and a few others on the forum have provided great support. 

I have taken your previously attached code and I think I have it close now to what I want done to display data on an LED matrix. 

However, it won't compile with an incorrect statement in the Interrupt code area (it is commented so you can see it). 

' ---------------------------
INTERRUPT
' ---------------------------
ISR_Start:

'RC = 0       'CLEAR DISPLAY OUT TO PREVENT GHOSTING
'Inc RA       'INCREMENT COLUM ADDRESS (RA I/O PINS)
'RC = NOT Display( RA )     'LOAD NEW ROW DATA TO RC

RC = 0
Inc RB
[b]testVal = GET_BIG RB[/b] ' PROBLEM IS THIS LINE OF CODE ??????
RC = NOT testVal
If RB > 63 then
RB = 0
EndIf


ISR_Exit:
RETURNINT 63


++++++++++++++++++++++++++++++

testVal = GET_BIG RB  

'or any value or number in place of RB (e.g. 0, 63, etc.) does not work.

 

However in the LOAD64 subroutine the "testVal = GETBIG pntr" does work. I tried moving the SUB statements before the Interrupt section, but it made it worse. 

Any ideas?  Anyone?

 

PS: I just received my BS2PX from Parallax today (UPS misrouted it and it took it a week overdue to get to me). I will start looking at this too to convert this code over LATER if possible (but no interrupts on the BS2PX).

Thanks,

Timothy Gilmore
