uC Hangs after second serout command
Hello,
I'm using the following configuration:
1 PIC 16F876A
PIC Basic PRO 3 (demo)
Why does the uC only runs this code one time. It does not loops it:
Code:
Include "modedefs.bas"
Define OSC 20

Re: uC Hangs after second serout command
NL2TTL,
Probably the code is getting hung up somewhere in the program. You need to determine where it is getting hung up. There are several ways to do it. I would move the next line around in the program and see how far the program goes
TOGGLE STATUSLED
This is just one way to do it.

Hi,
At first look I'd say you need to change the RETURN to something like GOTO Main.

Are you stating that because the status led is always on?
If this is the case, take note that you turn off the status led only in the subroutine CHECK_DATA and there is no gosub to this sub in your code.
Cheers
Al.
Re: uC Hangs after second serout command
Hi I take notice off that.
There are more strange things:
After the:
SEROUT2 XBEE_TX,84, ["Nieuwe kaart",13,10]
The uC starts at INIT again and does not go back to the main routine.

Re: uC Hangs after second serout command
In Check_Data you have RETURNs, but you're not using GOSUBs to get there, so replace the RETURNs with GOTOs to get back.
Re: uC Hangs after second serout command
Funny in 2.47 version of the compiler the timeout lable works with returns
I see that 3.00 does not accept the return.
Re: uC Hangs after second serout command
As far as I know, the timeout/label option has always used a GOTO to get to the label after the timeout period has expired. I can't say why it would have worked on an earlier version. Maybe luck...:)
Re: uC Hangs after second serout command
time out....go sit on the bench,
timeout only needed for serin !

Re: uC Hangs after second serout command
NL2TTL, The statement: Funny in 2.47 version of the compiler the timeout lable works with returns
I see that 3.00 does not accept the return. Only makes sense if the timeout actually happened inside of a subroutine. Otherwise, where are you returning to?
Re: uC Hangs after second serout command
could check PARITY BIT 13 in mode, manual says must=1
