OUR APPLICATION Operating the dsPIC30F with the CMX MicroNet TCP IP stack gives you the ability to send data across the Internet However you must decide how to use it in your design If you are simply looking for an interactive method of monitoring real time values as they are changing within your target device you may want to utilize the HTTP protocol and server already developed By setting up a series of URLs or links you can have the HTTP module format the information in the form of HTML files If you require a more efficient or a secure form of interaction you could set up a proprietary method of communication and deliver it within the payload of the TCP packet itself A Windows application could be created in order to communicate interact and manage a group of your devices on the Net One step further may be to give the ability of the devices themselves to interact with each other 2004 Microchip Technology Inc DS51471A page 59 PICDEM net 1 and dsPICDEM net 2 Connectivity Dev Board User s Guide NOTES DS51471A page 60 2004 Microchip Technology Inc dsPICDEM net 1 AND dsPICDEM net 2 CONNECTIVITY DEVELOPMENT BOARD MICROCHIP USER S GUIDE Chapter 5 FTP Server Demonstration 5 1 INTRODUCTION This chapter describes a sample program that demonstrates remote monitoring and control of an embedded application using File Transfer Protocol FTP communication 5 4 HIGHLIGHTS Information in this c
