i am trying to integrate a vectornav VN100 AHRS sensor to the paparazzi board (tiny2) through the SPI port. There is the code inside the modules/ins folder. I connected the wiring properly (I guess) and configured the module in the airframe file and added -DUSE_SPI, _DSPI_MASTER, DUSE_SPI_SLAVE0 too as cflags. But there is no connection with the sensor. Any help is highly appreciated
