[En-Nut-Discussion] Ajax on ethernut

[Ulrich Prinz]

Hi!


It is always an idea to attach simple to use and cheap external storage, to serve high volumes of data. You get several megabytes of FLASH in a serial NAND or NOR Flash chip for the price of only one SD-Card holder, not to mention the card itself. The use of axternal flashes is supported by Nut/OS and the flash file system is available too.
As Nut/OS supports FTP you can easily compile your application code including an FTP and flash it to CPU FLASH. Then you upload the server content to the serial-flash.
On AT91 an other powerfull CPUs SPI serves up to 25Mbit an more. Using PDC you can transfer the content from the SPI flash directly to the TCP queue without many CPU interventions. In the code you just need to handle the html tokens for AJAX/CGI.


Best Regards
Ulrich

Sorry... I misread your post [serves me right for replying before I've 
had my coffee:)]

Personally, I used ExtJS and Ext-core from http://www.sencha.com/
They've also just released "Sencha Touch" for working with touchscreen 
devices like iPhones and iPads, etc.

ExtJs would be quite heavy to carry if you've limited storage, but does 
give some mighty powerful widgets, and I find it very productive.

There's a lot of other choices, and for sites where you can assume full 
net access, you can save a lot of your own storage by using Google's CDN:
