SPI + I2C ?
Posted: Thu Jan 31, 2008 9:52 pm
Hi:
It is possible to use the hardware SPI and the hardware I2C at the same time?
When I am reading or writing on a spi device, I use the CS pin to select it.
But If I connect a external eeprom (to PORTC.3 and PORTC.4)
what happens to the eeprom when I am accesing the SPI...?
Or do I need to "float" the eeprom lines..?
Thanks in advance...
