WiFi connections

Post by basicchip » Thu Dec 25, 2014 1:03 am

Twas the night before Christmas, and a storm is moving through. White Christmas tomorrow, yeah get those skis waxed up...

Anyway, we've been working on a version of BASIC that runs on the TI CC3200, which is a dual core WiFi module, where we can grab one of the ARM cores and run BASIC on it. Actually it is pretty close to being ready for prime time, expect to be able to download code for it in January 2015.

But we also got sidetracked a bit playing with the ESP8266, available on ebay for around $5. Sure who needs FCC, it's $5. As long as you aren't trying to make a product looks like it might be a good tool for DIY projects. It is an ARM core, but has only limited IO, and already a bit overloaded juggling the TCPIP stack. So why not combine it with one of our boards. Initially got it hooked up to a SuperPRO or PROplus, and have a web page service that can interact with a BASIC program. We are thinking of doing the same with an LPC824, which for a couple bucks opens up the applications a lot.

Here is the connection diagram for the SuperPRO / PROplus. Expect some proto boards with the LPC824 in Jan.

You figure out how to load the SuperPro firmware via that little dongle, and you really will have made MY day!
I have (now) a bunch of them deployed, and I'm still having to take off access hatches to re-program.

Not to take away from the wifi angle, but couldn't you do an IR transfer???
Well, you'd still have to go to each station. Wifi you would be able to just
put their address URL in a database and loop through it from a 'server app'.
Okay - what Lloyd said....

Hi Bruce,

New gadget is looking awesome! It would be great if you could program it to look at an FTP server once in awhile to check for firmware updates! Store 4 parameters. Those being address, user name, password, and interval in minutes/hrs/days/etc.. It would be nice to have built in functions to work with cloud sites like http://www.mailparser.io or SparkFun's new free cloud server http://www.data.sparkfun.com
