Hi all

 

I am a college student trying to utilize SPI protocol as a method of communication between a master (MCF51JM128) and three AVR microcontroller for my final project. I wonder, is there any limitation regarding bus/cable length to implement the SPI? I have read somewhere that the cable length should not be longer than 20 cm. Is that right?

 

Thanks in advance
