Like anything in electronics, things change very quickly. We are now working with an ARM based WiFi module that costs only a buck or two more than the ESP8266. The advantage is that this one has enough horse power to do BASIC and serve web pages. We have some initial code working on it, and it merges a user BASIC program easily with displaying or updating BASIC variables in the web page. To program it, you use BASIC tools and combine that with some simple HTML.

So we will release the LPC812/LPC824 designs as open source.

We have a few of these boards to give away, we would just like you to use them and publish what you did with them

what was the outcome for this issue:?
'I took a look at the webpages.bas program and am curious about the HTTP_AD subroutine.
You refer to AD2,3,4,5 -- looking at the data sheet and user manual, the tssop20 uses
these ADC names - ADC2,3,9,10
corresponding to: name(tssop-pin) P0-14(20);p0-23(1);p0-17(2);p0-13(3)
1) are your AD4,5 mapped internally (codewise) to ADC9,10 respectively??
'
'
Thank you for releasing the hardware into the Open Source Hardware community.

I have a project in mind for an 824. I've got an esp8266-12 and a 4 opto-relay board to
use on my outdoor fish-tank. Lights, air-pump, circulating pump. [ I had trouble with my 812 HVAC
project with mechanical relays - inductive kick got into the 5v line and caused hangups]

again , Thanks Gary

On the TSSOP20 package only AD2 and AD3 are available.

Our code is based on more generic NXP code which only has AD0-7, but not all those pins are available on that package.

That code source in C is published in our MakeItC download.
