Hi

i want to assign a byte into a 500 byte array.when return from int,some times the microcontroller hangup.

sample code:

dim i as word
dim h(500) as byte

config int0=falling
enable int
on int0 assign_value

do
loop
end

assign value:
incr i
if i>500 then i=1
h(i)=portb
return

what should i do?

thanks

Perhaps is your code not complete, I see some errors...

assign_value to jump to, but there is only a assign value

enable int should be enable interrupts

dim i as word
dim h(500) as byte

config int0=falling
enable int
on int0 assign_value

do
loop
end

assign value:
incr i
if i>500 then i=1
h(i)=portb
return

Have fun

Hi,

Are your stacks large enough?
You also need to enable int0 and enable the global Interrupt:-

enable int0
enable Interrupts

Hi

thank you for note about code

yes,it is not complete code, i write here some part of its for example.

i test all section of my code part by part, all of code is about 800 lines and it is very complicate for reader to debug it, so i write the last code here to show my purpose.

for stack :

$hwstack = 40
$swstack = 40
$framesize = 50

thanks
