weewx, raspberry pie & LaCrosse TX22u
« on: June 05, 2017, 09:12:44 PM »
Hi everybody,

It's my first time posting on this forum, I'm a little bit newbie with weather stations but I'm using a Lacrosse wind sensor (TX22U) hardwired on the serial port of a raspberry pie and I would like to know if somebody already tried this kind of setup or as designed a specific weewx driver to interface the TX22U and it's own serial command.

Thanks and can't wait to see your suggestions...

Seb

if someone has already written a driver for the TX22U, i would encourage him/her to post a link to it with some of the other contributed drivers on the weewx wiki:

https://github.com/weewx/weewx/wiki

if you have the serial commands and any programming experience, it should take an hour or two to write a driver.  start with a simple driver such as texas weather instruments driver:

https://github.com/matthewwall/weewx-twi/blob/master/bin/user/twi.py

or the maxbotix driver (just the driver part, not the service part):

https://github.com/weewx/weewx/wiki/maxbotix

if you do not have the serial commands, then you'll have to create a serial sniffer (a physical tap on a serial cable - just a bit of soldering and a second serial connector), watch the serial traffic, then decode the commands and data.

post any questions and progress at the weewx development site:
