STM8 with WIZ550io This project add STM8 with WIZ550io for Ethernet connection.
STM8S Discovery board and WIZ550io. An optional RS232 adapter is used for debugging purpose.
The main program and settings of SPI is from this project using STM32 to connect WIZ500
Use the free version of COSMIC C compiler for STM8.
The IO libray used is from https://github.com/Wiznet/ioLibrary_Driver
Some changes are necessary because of name conflicts.
Use telnet to connect to defined IP and port. In this example, connect to 192.168.1.192 port 5000. The telnet client will receive a message and port closed.
For porting to other MCU, Ping.c need define Endian correctly for the function htons. STM8 is Big Endian, so nothing is needed to do. For STM32, ATMEGA, you will need to define LITTLE_ENDIAN.
STM8S Discovery Board, switch power to 3.3V(JP1 to 1)
