SPI Bus?

Archiver

Can the Basic Stamp be used with SPI Bus devices? How would this be done?
Also, Can someone explain to me exactly what an SPI bus is?


Thanks in advance,

Check out the Stamp Project of the Month
(http://www.al-williams.com/awce/som.htm).
This month I've interfaced an SPI UART from Maxim to the Stamp.

SPI is a serial bus that uses two data lines and a clock line. Usually one
data line is an input and the other is an output. The UART is odd because it
sends and receives at the same time. You can usually use SHIFTIN and
SHIFTOUT to talk to SPI, but in the case of the UART you have to do it a bit
different because it is bidirectional.

Hope that helps.

My article "Using Serial EEPROMs" describes SPI, Microwire, and I2C. It's
