You could always just do SPI in software, it's just a matter of twiddling some I/O lines.

But I found the wireless senging chip cc2420 also connect with atmega128 through SPI,and I cannot make sure that the hardware allow me to share SPI in different time. So,I want to ask you ,it there a good way to solve the proplem? Or,dose the cc2420 hold the SPI and we cannot use SPI to other way?? Thank you for your patience. Best regards, Johnson 04/20/2008
