Posted on March 05, 2015 at 18:58we are using the LSM303DTR. 4 wire spi. we initialize CONFIG 1,CONFIG5 and CONFIG 7 only....assuming defaults on all others. on power up, we get the pitch and roll always returning 0x8008 (our gui displays this as -...
Posted on March 23, 2015 at 23:28Why if the LSM303D a steady-state on a horizontal surface measures 0 g on the X-axis and 0 g on the Y-axis, whereas the Z-axis measures 1g = 1000mg?Direction of Z detectable accelerations is upward (see pag. 8/52 Do...
Posted on December 05, 2014 at 21:12I only seem to be able to power the LIS3DSH down to about 70uA by writing a 0x00 to CTRL_REG4 (0x20). CS is High. SEL is Low. I am using I2C. Running at 2.5V What do I need to do to get to the spec power down curr...
Posted on January 19, 2015 at 10:35how can i manage the self test in LIS3DSH.after enabling this option what i do? where can i found the result of test?
Posted on June 13, 2014 at 10:07after power up the LIS2DM the current consumption is about 100uA ?!The connection is:Pin1 : SCL with a external 4K7 to 3VPin2 : SDA with a external 4K7 to 3VPin3 : SA0 connected to GNDPin4 : /CS connected to 3VPin5: I...
Posted on February 15, 2014 at 11:59Hi, I am looking for SPI driver interface for magnetometer LSM303D thanks #lsm303d-spi-driver
Posted on March 17, 2015 at 13:38Does ST have any mems engineers?.... specifically an expert on the LSM303??? I'm having hardware issues with this part...(it is connected properly, board layout 100%, spi interface working.....not a hobby/hack deal.....
