No go so far I'm afraid tried the new code but there are a number of errors which I haven't checked out yet. Tried switching watchdog timer off and have put lots of capacitance across the 4.8 volt supply to the pickit2. (There are only three octal darlingtonds in circuit and there is no sign that the voltage drops when they are all on. The program runs until the "expanding multicolour disc" section. It then appears to go about seven times round the for next loop (For delay = 400 to 0 step -25) . and then starts again at the beginning of the program i.e. It resets. BTW Like the look of the shortened code although I haven't figured it all out yet !
