If the LPS27 pressure sensor works fine under I2C, I cannot make it repond through the SPI bus.
The SPI interface is setup as 4-wire Motorola format (phase 1 polarity 1). CS, the clock SCP and SDI are driven from the SPI controller; SDO is connected to the SPI interface POCI pin.
Is there something I forgot? Is there a special configuration to setup at power up to avtivate the LPS27 SPI interface?
I don't know what else I could try.
