If you had to choose between SPI and I2C on a single board, which one would it be?
I'd use SPI if I had one or two chips and only needed simple transfers of data from one internal register. Use I2C if you have a chip such as the Analog Devices AD7991, which has several registers to set operating modes. I2C is the only way to connect to it. Look for the external devices you need first and let them govern the type of MCU interface you need. --Jon
