[Paparazzi-devel] using SPI slave on Tiny2.11

Hi all,

I'm trying to use SPI to let Tiny2.11 and Gumstix talk to each other. The 
mission is to have Gumstix as SPI master and gather some data from some devices 
such as humidy sensors, heat- and pressure sensors. The gumstix will also do 
other things like controlling a GSM/GPRS modem to send the data to a data 
store. I want the tiny2 to be the autopilot and use SPI for communication with 
Gumstix. This means that it has to be an SPI slave since the Gumstix is the 
master. The problem is that all the modules in paparazzi are using the SPI as a 
master. There are some definitions for an SPI slave in the hardware code for 
SPI but I don't see any other code using that. It would be good to know if 
anybody else is working on a similiar project. Is anybody else using the Tiny2 
as an SPI slave?
