EB390/D 5/2002 Porting AN2120/D UDP/IP Code Avnet Evaluation Board
Motorola application note Connecting M68HC08 Family Microcontroller Internet Service Provider (ISP) Using Point-to-Point Protocol (AN2120/D) describes methodology connecting Motorola microcontroller Internet using protocol exchange UDP/IP data. UDP/IP (user datagram protocol/Internet protocol) similar TCP/IP, except that being connectionless protocol, sends messages host without establishing connection. AN2120/D also includes code that implements UDP/IP protocol. This code first developed using Cosmic development environment. Since then, UDP/IP code been ported Metrowerks CodeWarrior development environment1 onto 68HC908GP32 Avnet evaluation board. UDP/IP methodology provides mechanism allow remote device, this case M68HC08 Family microcontroller, connect ISP. When remote device established connection with ISP, remote device broadcast data other hosts Internet. UDP/IP network connectivity illustrated Figure

This debugging discussion deals with issue network establishing connection. steps resolve this type network determine network designed remote device must configured accept connection. Debugging network, this case, requires understanding network implemented what configuration network functional. addition, requirements remote device must considered. remote devices must compliant with network's design structure protocols. When network configured correctly, devices will connect. Defining, Setting Configuring Network With understanding network design connection capabilities, network restrictions, underlying communication protocols (i.e., TCP/IP NETBEUI), user configure network remote devices. configuration process network remote devices this demo illustrates this. overview configuration process included below provide guide define network.

UDP/IP connection implemented with different network configuration, using instead dial-up server example, correct network setting must implemented. guide above applies other network setup variations well. Following this guide will ensure that network defined correctly.
Network Connectivity Debugging
Once device establish connection, network still require tweaking. primary problem that arises that devices unreachable network connection misdirected. that case, network address, network port information, modem setting, network components, network protocols, server type must reviewed, and, with this information, server (ISP) remote devices tweaked necessary described section entitled Defining, Setting Configuring Network.
