Digital readout is nice but for $100 needs an Auto-Off timer feature… 30 minutes no use and OFF.

I’ve been working with the RN-XV for a few weeks building a WiFi Garage Door Opener (cool project) and I got to say it’s been nothing but a struggle using this module. Why - because the documentation sucks! The RN-XV data sheet doesn’t even show the three status LED’s, it’s just incomplete! Basically they took the RN171 and put an IP stack on it and renamed it the RN-XV but there are other subtle changes as well and many inconsistencies. So you really need three documents to try to understand what’s going on (RN-XV Datasheet, RN-171 Data Sheet, WiFLY User Manual & Command reference) plus a lot of on-line research.
IMO they need to complete re-write the GPIO and Analog sections so they make more sense. The implementation could be easier too, having the deal with the bit masks and reference that to actual pins could have been done better. In fact they use 0 for input and 1 for output… why not O=0, I-1 like the PIC? Another grip I have is there is no command reference table or summary. You need to scroll through pages and pages to find what your looking for.
So I did finally understand and get all my GPIO working, and then wanted to use an analog sensor pin for a TMP36 temp sensor and hit another brick wall. The documentation is SO POOR on this part that your lucky if you have a clue to what’s going on. After much research on this I finally found the best answers here on this forum.
This might help anyone wanting to use these analog sensor pins. Now is this a cool device - YES Absolutely VERY COOL so let’s hope that Microchip (assuming they acquired Roving Networks?) can get the documentation and examples up to a higher standard that make it more fun to work with!

Personally I would never use this “slamming technique”. Get a Hakko 808! Well worth if you do a lot of desoldering. Doesn’t stress the board if used properly and it’s pretty easy to clean and maintain. had mine for several years now.

I ordered a few of these inexpensive rotary encoders to play with and electrically they work fine. I have some simple PIC test code to inc/dec a 7-segment LED and seems pretty reliable. What I don’t like about this part is the action… it’s too easy to get stuck in the middle of the 12 indents, especially when turning slow. I’m assuming a higher quality part would do a better job of only stopping on the 12 position indent and not in the middle of two positions.
