Hi,
I am working on a arduino mega 2560 project that sniffs 12 bit SPI data being output from an ADC sampling at 1.5 kHz repetition rate with a 1 MHz SPI clock on an existing board. Note that this is a slave and the SPI clock, SS etc are generated on the existing board. My intent is to then transmit that on a either a serial port or direct USB connection. I have code working that receives the first 8 bits but don't know what to do with the other 4 bits that wiz by.
Is there a way to accomplish this with the standard library or should I look into software SPI?
Thanks in advance, Bill
