Me again, but need REAL help now

[gringobomba14]

O.K. I Searched, found the code for the SHT71, thought I understood it, and am now more confused than a porcupine in a brush factory. I am trying to make a 16F877A have a generally good conversation with the SHT-71, and display the results on an LCD. I have mastered the LCD bit (really easy with picBasicPro), had an LM35 read an analogue temperature, but I just can't get my head around this SHT-71. is there anyone out there who has a few minutes to write an idiots guide??? Or has anyone got a finished full code so that I might learn from it??

Thanks in advance,

Gringo

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

Hi,

Some ideas ( in english ! ) There :

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...
