I would like to know if it is possible to have an SPI interface with the propeller.

I need to connect several ADC chips to the propeller using SPI. The idea is to read the info of each ADC in order, using the same SPI channel.

Help is welcome!

    There are several objects in the Propeller Object Exchange for using different ADC chips with the Propeller, most with an SPI interface and some with an I2C interface. You can't use the same SPI channel for several chips. Each chip must have at least its own chip select line. The clock and data lines usually can be shared. There are a lot of SPI devices used with the Propeller, many with existing drivers in the Object Exchange, including different kinds of memories, SD cards, ADC chips as mentioned.
