Thank you very much Ttelmah!

I overlooked the fact that an UART pin normally goes high. (My hardware already changed the polarity for me and I measured only at the SDI-12 side.

I made the choice ...

Hello,

I'm trying to connect a PIC18F8722 to a #use rs232(baud=1200, BRGH1OK, parity=e, bits=7, stop=1, xmit=PIN_G1, rcv=PIN_G2, ERRORS, stream=SDI12)

Now sending works as expected (chec ...

Hello,

I am trying exactly the same as described above. Now I cannot recreate an easy version.

What I try to do is make common functions in one file and include this file with the bootloader. Th ...

For more reactions you might want to explain your problem a bit further. I can understand what is going on, but I do not entirely know what you want to happen.

I suspect you want to get rid of the ...

I would say: look at your voltage divider.
What sort of hardware do you use to get these high voltages to the low voltages the PIC accepts?

If this PIC however supports high voltages (I'm unaware, ...

Hello,

I have updated today to version 4.084 but this gave me trouble. I cannot connect to my icd since this update. It only gives the message: try power cycling the icd.

When I go back to my pr ...

CKielstra is right, give some more information and the replie you get are more to your liking.

What I think you search for is the following:
int32 data = 23832442;

printf("DATA: %l ...

I've never seen a PIC not just start after a clean power-up unless it was broken. Yours is running after some RS232 communication so I suspect the problem is in your software.

If you post your code ...

2 things come up in my mind:

first: How are ClientID and ID defined?
second: Buffer is bigger than AIS_String, how do you handle this possible overflow?

AS answer on your question about handlin ...

first: can you post your simple test program? The guys here can give you more useful hints and tips when they see your code.

second: the compiler v4.016 is known to be buggy, in fact all compiler b ...

most modems I know turn at command echo off with the ate0 command...

But I can advise you to make a more advanced respons filter. Maybe you should try a receiving buffer or something like that? Sea ...

there is a modbus example included with the compiler.

Look in your examples file

I think you should connect the Slave Select Pin to a output pin of the master. Then, when the master starts communication, the master should first take this pin low, and after that send the spi data a ...

Why not just delete the line Intcount = 0; ?

This way the Intcount will overflow to 0. (as long as it is an int)

It is not the most dynamic approach, but it works in this case.

you could try adding the #separate directive in from of your calc_windows() function.

like this:
#separate
void calc_windows()
{
...
}

If this works, your ROM is not to s ...
