Let me re-phrase that last comment
Ya gotta page thru the resulting .asm and possibly .lst file to figure out where the problem is. Then trace it back to the source code lines.

Hi,

May be

Loop:result = result - 1 :if PORTD.0 && result.11 then Loop'

instead of

Loop: result = result - 1 : if PORTD.0 & result.bit11 then Loop

... here it compiles !

may be you're not LOGICAL enough ... LoL !

Good one!

Yep, I finger-flubbed that one apparently...

Excellent help guys. Compiled with the && so I learned something new today....... but now I just get 16 on Humidity and Temp. I have a 10K pull up resistor on the DATA pin of the SHT71, and the leads are about 5cm long. I found that the program stops here:

ReadSensor: gosub TransferStart : gosub WaitSensor
shiftout dpin,cpin,0,[Sensorcmd\8]
input dpin : cpin = 0
while dpin = 1 : wend
cpin = 1 : pause 1 : cpin = 0
while dpin = 0 : wend '<-----------------program stops here
so obviously the Data pin is not doing what its told to. Any more ideas out there???

How do you know the data pin isn't doing what it's told to do?
How do you know that the sensor received the Sensorcmd correctly in the first place to trigger it to kick back some data at you? Do you even have to wait for the dpin to go low and/or high? How about just pausing for a bit longer and see what happens?

All good questions............let me stick some LED's in there and see whats going on then
