[wxsig] Family Codes and ds2438

While you are on this topic.  Can you recommend which 1 Wire products are
compatible for use with the T238+?  I am looking for a Humidity/Temp sensor
and a barometer.

I purchased a Humidity/Temp sensor from AAG, but it has since failed.
I purchased a barometer from hobby boards and it is not compatible.  I think
it uses the ds2438.

Thanks and let me know what you think.

You have the right idea.  I had actually written you a reply several days
ago that I "discovered" in my drafts folder.  Let me review the two emails
and get back to you in a day or so.

Hi Will:

I tried to solve by myself the problem with ds2438's clone.

What i have done:

1- downloaded all code from your website.
2- downloaded casm08z.exe from pemicro
3- I walked trhough the code, and found 2 files with related entries to
family code 26:
	wx08.asm, and humid.asm
4- Change any prefix 26 into A6
5- compile the code
6- upload to the 238+ with mon08 program.

When done, t238+ works, so compile process went good, (it did not give
any bad message), but humidity keeps on not being showed on the screen.

What i am doing bad?

Did I miss any other place to tune?

Is this process right?

Thanks in advance.
