Thanks for noting. Done

Ask Geo service has updated their service and new posted code here incorporates the changes required.

For me uninstalling Secretlabs SDK and .NETMF and the re-installing 4.1 helped (and it uninstalled GHI too). The 4.2 was somewhat useless for my project as I could not fit the program into memory of the N+.

The N+ only stream out data, that is it tells the uVGA (or other 4D screen) current temp is X and humidity Y and moon is Z etc.
The N+ also tells the uVGA the time and date.

The uVGA itself then is running a program I wrote (it is programmable using 4GL language) that split the screen to tiles, changes font sizes, colors and what have you. Icons and bitmaps are stored on SD card of the uVGA. That code and content of the SD is part of the ZIP file.

The N+ updates the uVGA only once in few minutes. In the mean time an internal timer on the uVGA is interrupting once a second so that you get a clock with seconds displayed.

Both N+ and uVGA have very inaccurate timing, but the N+ is slightly better. This is why the NTP is polled once in 6 hours and fixes the drifts of the N+ time, and then the N+ is also updating the uVGA.

The uVGA has two firmwares, the one I use that requires you to program in 4GL and another one that lets you send graphical commands from UART. Switching between the two is simple. Take a look at their site.

Thanks Hanzibal! Regarding #1, yes I do determine location based on external IP of the network the N+ is connected to. Good enough for weather information and likely to work at any home. Proxies will cause some problems. Regarding #2, I am not sure exactly as the screen I used does not report the complete VGA settings. It is a 800x480 in resolution but not sure how many Hz for the refresh. If your question is about the speed at which the display is updated, it is very good. The reason is the mentioned adapter has a "GPU" on it from 4D Systems, and all the graphical commands and layout of screen is done on that "GPU", and not by the N+.
