Lots of parts use I2C. Used it since my HC05 days. That's now 20-years ago ! http://en.wikipedia.org/wiki/I%C2%B2C You might be thinking of the DS1307. It needs an external 32KHz xtal. I2C Interface is a bit odd, but manageable with modern uCs. Many uCs have dedicated I2C ports, but its simple enough to be made from 2 general purpose IO bits. Especially if you are just using a single "master". SPI, on the other hand, is simple enough to do exclusively in hardware. That's if you choose to do it that way. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To post to this group, send an email to [email protected].
