OK, experts.  I need held. B_A_A_A_D

Here is my code for driving a 595 shift register, at the present time uss an
F877 in Flash Lab.


serout2 so, 84, ["Starting", 10, 13]
low PortB.1
serout2 so, 84, ["Low latch", 10, 13]
shiftout PortB.2, PortB.0, msbfirst, [%10101010]
serout2 so, 84, ["Shiftout", 10, 13]
pulsout PortB.1, 100
serout2 so, 84, ["Pulsout", 10, 13]
low PortB.1
serout2 so, 84, ["Receiving Plan", 10, 13]

The debug screen displays

Starting
Low latch
Shiftout

but never gets to the "Pulsout",  It just goes back to Starting.  It's like
it doesn't like "pulsout PortB.1, 100" and just ignores it and restarts.

Why ?

Someone's going to say it, so I might as well...

Wrong list for that buddy.  :-)

Otherwise, no clue what Flash Lab is.

Assuming the code does what I think it does, I'd look at what is
connected to portB.1.  It could be you are causing brownouts/shorts by
pulsing that pin, or creating too much noise.

I'd isolate that insturction and see if it does it by itself.  Chances
are the program is ok, but not the hardware.

Hi,

look at the assembly listing and/or the pulsout routine. Obviously u get a
WDT restart which is very well possible at 100 msec delay. Or you may
experiment instead of 100 say with 8 to check whether I'm right.

Regards,
Imre
