Software SPI

I need to acess a device using SPI with the Zigbee modules, this of course is an issue becuase the lines are nor broguht out. I searched the forum for software spi which yielded this...

http://forums.freescale.com/freescale/board/message?board.id=8BITCOMM&message.id=15&query.id=2514#M15

which may or may not help... I have to dig some, but does anyone have any links or resources for setting up a software SPI port.... the zigbee module would be the master and the device is the slave..

thanks

Hi Mike,

Here are some documents that implement a software spi:

Hi Peg,

I see you're an expert in the documentation
You should apply for a job in Technical Publications !

Cheers,
