status of atmega 128 now on aug- 2009
Hi,
I only use the Pic micros and when I tried to do the same with a SHT10 I soon came to a similar halt.
It uses a Serial method of communication but its a custom software method as shown in the datasheet, using standard i/o ports, and you have to write the complete routine as its unique to those sensors.
Unforunately thats only the begining of the hard work, once the data is received it has to be 'converted /linerarised ' to produce the final results for displaying.
I could not understand how to do that at all, one for the gifted maths guys, fortunately a lot of searching did locate one program in Pic Assembler that I could use and adapt to my chip etc.
If you are programming in C there are several bits of code out there including Sensirons site.
If you are doing it in Assembler you might find something for your chip or possibly my Assembler code might a least give to at path to follow.
