Hi, I need to Read sensor with ADC(AD7730) and then send out value continuously via Rs232 or Rs485,or turn off or on some GPIO Pins but for calibration (in Application layer) I wanna use from web management(Http server). The user must be able to login to device using LAN interface and change some Values. Can I use From NXP LPC 17xx and FreeRTOS? How Can I do it? How Can I start? Please Guide me Regards,Hesam.H.Motiee

There are lots of ways you can do this. Have a look at http://www.freertos.org/FreeRTOS-Plus/Nabto/Nabto.shtml for a light weight option. I think the live demo is running on an LPC1769.

Hi, thanks for your attention,Nabto is realy amazing but you know the system should not be dependent on an Internet connection to work,I need to local direct connection to device(for example connect to printer server or ADSL modem routher via browsing 192.168.0.1 and then set configurations). Please tell me more,how can I start?What PCB should I use?

I’m not sure if it relevant as I don’t understand your requirements/topology, but Nabto does not need an internet connection to work, it is quite happy on a local area network. Regards.
