Original post: http://kaizen8501.blogspot.com/2014/10/frdm-kl25zwiz550io-shield-porting-guide.html WIZ550io Shield-A is arduino shield for using ethernet more easy. FRDM-KL25Z is also compatible with arduino shiled. So If WIZ550io Shield-A attach on FRDM-KL25Z, it can use ethernet easily. But WIZ550io Shield-A has some problem. If using Arduino Board, it has two method to use spi signal. First, it can use Digital pin 9 to 12 for SPI communication. ( 9: SCSn, 10: MOSI, 11: MISO, 12: SCLK ) Second method is using ICSP. But WIZ550io can support only second method for using SPI. So I did need…
