I tried to make the WiFi Shield for GR-KURUMI.
For GR-KURUMI WiFi shield, WizFi250 is select as WiFi module which provides UART-to-WiFi and SPI-to-WiFi.
To test simply, FI250 library which uses UART interface for Host Interface is select as WiFi Library.
GR-KURUMI and WizFi250 could be connect to “Serial1″: serial1 is UART interfae which is consist TXD(7) and RXD.(8).

WizFi250 Shield is one of Arduino WiFi shield. WizFi250 Shield is consist of WizFi250(WiFi Module) and interface board which has Arduino connector. There are 2 kind of WiFi shield by using WizFi250. (WizFi250-EVB and Fi250)WizFi250
WizFi250 is an WiFi module for embedded system and provides UART and SPI interfaces which enable connections to any embedded design utilizing an 8/16/32-bit…
