[Paparazzi-devel] barometer ms5611

[Cédric Marzer]

> 
> Hi all,
> I made a custom board (STM32F4) with the barometer (ms5611) and the MPU 
> (MPU6000) that share the same spi (spi2). It is similar to one of the aspirin 
> configurations.
> My problem is that the MPU is working fine but the barometer doesn't.
> I tried to use it with or without the corresponding module without success.
> 
> My changes to the baro_board.makefile are the following :
> 
> # imp baro
> else ifeq ($(BOARD), imp)
>  BARO_BOARD_CFLAGS += -DBARO_BOARD=BARO_MS5611_SPI
>  include $(CFG_SHARED)/spi_master.makefile
>  BARO_BOARD_CFLAGS += -DUSE_SPI2 -DUSE_SPI_SLAVE0 -DUSE_SPI_SLAVE1
>  BARO_BOARD_CFLAGS += -DBB_MS5611_SPI_DEV=spi2
>  BARO_BOARD_CFLAGS += -DBB_MS5611_SLAVE_IDX=SPI_SLAVE0
>  BARO_BOARD_SRCS += peripherals/ms5611.c
>  BARO_BOARD_SRCS += peripherals/ms5611_spi.c
>  BARO_BOARD_SRCS += boards/baro_board_ms5611_spi.c

> The board C files contains the following lines (I tried with both the
