Posted on October 10, 2013 at 02:52The RDY is used to indicate a new data is available. The problem is that the ODR can not greater than 160Hz,otherwise after a period of time of dataoutput,the RDY goes low,and the value of STATUS_REG is changed to ...
Posted on October 12, 2013 at 08:30hi,guysI'm working on LSM9DS0 with STMEVAL-MKI109V2,using 4-wire SPI communication?read gyro's WAI reg is ok if keep CS_G=0 and CS_XM = 1 after EVAL board power on, but if CS_G=0 after CS_G=1 and CS_XM = 1,read WAI...
Posted on November 13, 2013 at 00:38If I measure the zero rate level for a few seconds, I can get an average measurement and use it to cancel out drift. However, the zero rate level changes over time. I want to choose a gyro with the smallest drift....
Posted on November 05, 2013 at 10:01Hi, So time to get right to it, I am using 2 LIS3DH Accelerometers ( Two Different Addresses Assigned to them), they are both using the same I2C lines and the same INT line on my microcontroller. That is the way...
Posted on October 23, 2013 at 11:48As Interrupt sources, what means the ''X/Y/Z High Event'' or ''... LOW Event'' in the datasheet? Are there defined trigger values for these events, and are they changeable in some registers? #h3lis331dl #acceler...
Posted on October 22, 2013 at 16:32Hi,Where are the land patterns for LIS3DH, LLGA16 (3x3x1.0) 7983231 filed?I have tried searching for all of the above keywords but still come up empty handed, the closest i get is a land pattern by maxim, 90-0396.T...
Posted on November 14, 2013 at 08:34Hi, The accelerometer was generating the interrupt when the value of CTRL REG 3 was set to 0x80. But AS CHANGED TO 0x84 to check the latch interrupt request there is no more interruppt generation. Can anyone prov...
Posted on November 13, 2013 at 18:10Hello, I need to configure a LSM330DLC in a way outlined in the DT0005 document. Essentially, on data ready interrupts (INT1_A) from the accelerometer feed into the DEN_G pin, telling the gyro to push a conversio...
Posted on November 05, 2013 at 18:21Okay - I've got data flowing from the L3GD20 into the microcontroller using the DRDY/INT2 signal. As I examine the readings that I am receiving from the sensor chip, though, it appears that I receive ''bogus'' va...
Posted on November 02, 2013 at 07:04Different LIS2DH chips shows various frequencies even they are all configured at 400Hz. The actual frequency value can range from 390Hz to 400Hz.
