Build a true Webserver with only 2 chips. We did it! The used CPU (MSC1210Y4 from Texas Instruments) has 16kB Flash (up to 32kB available) and 1.2 kB RAM. Enough for a Webserver (provided you are using uC/51โs included TCP/IP stack).
Add Internet-Connectivity to your Applications with only a very few lines of C-Code. Many demos are included in uC/51, like: Webserver, E-Mail, Time-Client, TCP, UDP. Make Control System with remote Internet access to your sensors or actuatoors.
