16MHz SPI? #2

Closed AloyseTech closed 8 years ago

AloyseTech commented 8 years ago

HI, in the spitx example, you setup SPI at 16MHz, isn't the SPI of the zero constrained to 12MHz? It would be great if 16MHz is achievable though. By the way, thanks for bringing a DMA lib :smiley:

yep, it is limited to 12mhz (24mhz does work but is not recommended per atmel)
