The driver mentions that the first group of sensors have a WAI of 0x3c: #define ST_MAGN_1_WAI_EXP 0x3c And when I print out the WAI read from the device: Requested device: lsm303dlh_magn - read WAI: 0x3c I guess I could have been lied to again by the board's datasheet again and the attached device isn't actually a LSM303DLH, but how can I tell for sure? -- Lee Jones Linaro STMicroelectronics Landing Team Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
