lacross tx20 on arduino

Hi,
I read here Arduino Forum
that's possible to connect the wind sensor on arduino, but after few hours, I'm a little ]:smiley:
in this topic, it's write that 37bits data but on an other website it's write 41bits data (La Crosse TX20 Anemometer Communication Protocol – john.geek.nz)
If somebody have code to do it, it will be fun

thank's

Ciao,

maybe this link can be useful (TX23 and TX20 protocols should be the same)

In this section of his 3 pages TX23 website You can find how he fixed the "timing problem".
Code is for PIC, but can be adapted for the ATmega.

You can also use Arduino as logic analyzer.

Ciao,

I saw the two links yet, but don't works.
the tx20 have an other cable.
in the italian section they talk about grd for this cable.

thank's for the other links, I'll take a look on it.
