No sign on life in a chip...

I just recieved the breadboard for the 2p40 chip i have from a while
back and upon updating an older 2p40, i go to load the sw into the
chip and the software says it was successfull.
Problem is one of the commands is to make mainau pin15 on but the led
does not light up.
I assume that if it loaded the sw the chip is not toast right?

Generally true, but one port may be blown and the rest of the chip may be okay.
Did you use the appropriate AUXIO or MAINIO command in the program ? Is the LED
connected correctly ?
You might also want to change the port assignment and try a different I/O port
to see if Port 15 is indeed blown. You may additionally want to add a DEBUG
statement as the first thing in the program: DEBUG "Executing" to ensure that
program execution has begun.

16-31 aux I/O. could you post your program? if not just simply do the
following
i always use the debug command when using outputs. it kind of prevents the
stamp from going to sleep.
also make sure the LED is good.
Debug cls
main
high 15
end

going to sleep, but you may need to use it on your laptop computer to
keep the serial port from going to sleep.
The BS2p40 has two groups of pins: MAINIO and AUXIO. You must first
select the group, then pin fuctions will work in that group thereafter.
So, if you want to turn on AUXIO P15, you would do this:
Test:
AUXIO
HIGH 15
STOP
And yes, make sure your LED is good before assuming you've got a duff
Stamp.

mainio
output 15
test:
out15=1
pause 1000
out15=0
pause 1000
goto test
Then i put the volt meter to the pin15 and it read 0 volts for a few minutes.
It send the commands into the chip successfully and that is why i wonder if the
chip itself is hosed.
Thanks

Pins 16-31 are addressed as pin 0-15 as well. You have to add the AUXIO
command to access them, then remember to include a MAINIO command when you
want to address the main pins after having used the AUXIO command.
Forgetting the MAINIO or AUXIO has buggered me more than once.

all of the stamp I/O lines are OPEN COLLECTOR. A pull up resistor 1k to 10k
should be fine, MUST be used to achieve valid logic states.
