serial comm from Pic to STAMP

[d1camero]

Hello, I am new to uProcs, Pics and PicBasic, but things are going well.

I am using SEROUT2 to communicate with a Basic STAMP and it appears to work well, but the STAMP only receives every second transmission. I hooked a scope to the serial line, and yes, the PIC is transmitting correctly.

Here is the PicBasic Code:
<code><b>
@ Device PIC12F675,WDT_OFF,PWRT_ON,PROTECT_OFF,MCLR_ON,BOD_ OFF 'sets configuration

INCLUDE "modedefs.bas"

Serial VAR gpio.2
Stuff VAR word

TRISIO = %00000000 ' Set all ports to output
CMCON = %00000111 ' Disable Comparators
ANSEL = %00000000 ' Turn off all ADC

Pause 1000 ' Wait to allow Hardware to Settle

gpio = %00000000

' Loop, sending a value out on the serial line
Stuff = 0
testloop:
stuff = stuff + 1
serout2 Serial, 16780, ["Value:", DEC Stuff]
PAUSE 1000
goto testloop

END
</b></code>


And here is the BASIC Stamp code:

<code><b>

'{$STAMP BS2}
'{$PBASIC 2.5}
INPUT 0

Value VAR Word
Waits VAR Word

Waits = 0

DO
DEBUG HOME
DEBUG "Waiting... ", DEC Waits, CR
SERIN 0, 16780, [WAIT("Value:"), DEC Value]
DEBUG "Got Value. Value=", DEC Value
Waits = Waits + 1
LOOP


END
</b>
</code>

Any ideas?

thanks

Found the problem: with the SERIN command, when expecting a number, it will read ASCII numbers until a non-numerical ASCII code is discovered. Since I did not put a CR on the end of the SEROUT2 data, the STAMP reads the number, then waits for the next non-decimal ASCII - which is the next transmission. The remainder of the transmission is tossed, because the stamp is then waiting for "Value:"
