Me again, but need REAL help now

What else have you built so far? Anything?

Hi Ski,

Yes, I built a temp/humidity regulator, using the PIC16F877A, an LM35 temp sensor, and a non linear resistive humidity sensor, with 2X16 LCD, and a user menu to set the paramaters. Once the temp or humidity goes outside these paramaters, a relay is triggered (Through a ULN2003A) which will switch on either a humidifier, dehumidifier, heater, cooler. But the analogue stuff isn't very accurate which is why I'm searching like a maniac for help with this digital stuff.

Apart from that, various LED strobe kits for volunteer firefighters, again using the darlington pair chip, which can give you current output of 500mA per leg, or more if you run them in parallel.

But I'm still a newbie

Well, all that being said, that link posted above should give you one heck of a head start at getting that SHT71 working without much problem.

Excellent guys, thanks. The conversion to PicBasic doesn't look too hard, so thats my project for tonight. Wish me luck!!!!!!

Actually, I had my mind in another thread with that last comment.
The link above to mikro is good, but if you search HERE, on these forums, you'll find some code practically already done, waiting for your modifications.
Ya know...that search button, towards the top of the page, offset to the right a bit, little down arrow next to it, white letters, blue background...

Done that a few days ago, and was lead to the SHT-71 code by cocacolaKid. the thing is, I don't understand the code well enough to make the correct mods. Unfortunately, maybe I'm not as well up on PicBasic as I could be, so I don't fully understand "shiftout DataPin,clk,1,[SensorCmd\8]" DataPin and CLK are pins on the SHT, so I define them, but SensorCMD/8????? No idea. Some hand-holding seems to be the only answer......

but SensorCMD/8????? No idea. Some hand-holding seems to be the only answer......

"SensorCMD\8" isn't in the book, but the definition of what those positions in the command "SHIFTOUT" are fully explained in the manual.
