ATMEGA8535 SPI to DS1305 nvram
2004-06-04 by sguhrofst8
can anyone help. I have not been able to successfully talk to my nvram on the DS1305 using the SPI interface from the ATMEGA... I am not using the the calendar/time, etc options of the DS1305 just the memory. It seems that each time I read the SPDR register, it contains the last byte i sent. Thanks in advance.
