【正文】 nter generation. Based on the existing embedded Inter and pared several recent microcontroller access Inter, under the precondition of realizing scheme used a based on single chip the characteristics of its own specific solution: embedded TCP/IP protocol. Based on TCP/IP work protocol, the indepth analysis of TCP/IP protocol, reasonable simplified embedded in its limited resources to the interior, so as to realize microprocessor by Email remote data transmission.
