Serin serout problem

[lerameur]

LCDOUT "datain: ", BIN 5 ------------- ???? what's this for?
I was just testing my LCDout

lcdout $FE,$C0, "datain2: ", bin encoded22.HighBYTE , ".", dec datain2," ",$DF,"C" ---------- where is datain2 getting set at?
Past program , forgot to remove it, was just using the first line for LCDout


In the receiving chip, nothing is happening, its going in but not recognizing it.
This is the code I have, nothing is going to the lcd screen. If I remove the SERIN line, then the LCDOUT work, but gives me all 1. (thats normal its not seeing anything)
How do i output this on the lcd ?
It seems that i cannot use the command SERIN and LCDOUT in the same program...


serin portB.2, n2400,[ encoded22.HighBYTE, encoded22.LowBYTE, encoded11.HighBYTE, encoded11.LowBYTE]

LCDOUT "d: ", BIN encoded22.HighBYTE ,".",bin encoded22.LowBYTE ---------------------not outputting what i want
lcdout $FE,$C0, "datain2: ", bin encoded22.HighBYTE , ".", bin encoded22.HighBYTE," ",$DF,"C"
Pause 500

Little steps like I told you before...
Get the basics working. Add in the temperature correction code after you get the basic temperature displayed. Blow on the element, make it change, get it 'in the ballpark'. Forget about the encoding/decoding. If you can't get temp to be displayed as it is without the wireless, how are you going to get it to work with the wireless? Magic? Me thinks not...
Make your LCD work for you. Notice I added a bunch of lines telling me what the PIC is doing. Use them often!
And you had your C to F conversion backwards, and there was no way your original program was going to work. You had your decoding happening after you displayed the results. If you're going to send the whole code, send the whole code.
Post back when this works. If it doesn't work, you've got other problems, hardware.

about the LCD_RWREG, I stuck my lcd pin to ground, so it should always be write function.

I still get the same problem , The lcdout do not display the inpuT from serin. tHE LCD shows on the second line : 'Waiting...'
It seems to me that the as soon as it sees the serin command it skips all the lcdout afterward, and loops again.

LCD_RWBIT....ok, understood. I'd define it anyways to an unused pin just to keep PBP from thinking otherwise.

Screwed up a bit overall. You can't send words thru a bytewide serial port!

Try this instead:

The same thing is happeneing as before,
the LCD is just showing 'Waiting ... ' on the receiving unit
And I can see on the scope a signal coming in on portB3

Anything showing up on the first line? Something like:
Tc=100C,Tf=212 or anything similar?

[lerameur]

the first line of the receiving unit is blank
the second: waiting ....
