Hi, How can I connect many components with SPI interface on the same McBSP port of a TMS320C5416 ? Thanks, Jerome |

If they are really SPI (Clock, Data in, Data Out and ChipSelect) then you connect them all to the SPI bus (clock,din,dout) and use a GPIO line for the chip select of each device. I2C is a bit nicer for things like this, each device has a unique ID that can be addressed over the bus and you don't need a seperate chip select for each. Brian ----------------- Brian C.
