Hi Group, I have a few questions about creating a custom device connected to the internet. The device will have two primary functions
1) act as an embedded (dynamic) web server with the ability to download new html code remotely
2) act as a conduit to a microcontroller where TCP/IP packets can be sent and received with a simple protocol riding on top to control stuff (say switches and lights for arguements sake) Interface to microcontroller could be parallel, SPI or RS232.
The device would act as one or the other and sometimes both. At this point there is no particular requirement for amount of html code, speed, cost, security etc. I have a Coldfire development kit and have the option of writing the code from scratch based on PD tcp/ip routines but I don't want to spent months creating the ability to download dynamic web pages remotely. I have also looked at some devices like the Digi connect ME or XPort devices. It would appear that they would make a good stand alone web server but it is not clear if they are restrictive in terms of sending raw tcp/ip packets. I also don't know if I can download web pages remotely to these devices. I can provide more details if this description is too generic but I also don't want to make this post too lengthy. Basically I am looking for any advice concerning off-the-shelf modules vs. writing the code from scratch and pros and cons of each. Thanks, Max
