I2C1 hangs at while(!I2C_CheckEvent(MPU6050_I2C, I2C_EVENT_MASTER_TRANSMITTER_MODE_SELECTED));
Posted on July 19, 2012 at 09:48 I have STM32-P103 board which uses STM32F103RB micro. I connected I2C sensors to I2C2 pins as shown below : I use only 4 pins of the sensor, SCL, SDA, Vcc, GND.I have the following Initialization code ...
L3GD20 DRDY stability
Posted on February 06, 2014 at 09:59Hi, I'm testing L3GD20 with SPI on my small test board. It looks like OK so I can get gyro data and DRDY signal with 760Hz. But when I monitor DRDY signal with my oscilloscope, it has a jitter sometimes. The dif...
A3G4250D data conversion
Posted on February 06, 2014 at 04:50Hi, I am evaluating the A3G4250D gyroscope, could any one give me formulae or steps to convert the gyro and temperature data into deg/sec, degC respectively. Regards, Kantha
Start-up state of L3GD20 and SPI bus
Posted on January 10, 2014 at 20:15On power-up, does this gyroscope come up in operating, sleep, or power-down mode (i.e., when all SPI peripherals in my instrument are powered up by a common bus, how much is the gyro drawing?The datasheet says that...
Want to evaluate the new LSM9DS0 and LSM303C, what evaluation board do I get and what software?
Posted on December 04, 2013 at 10:11I'd like to evaluate the LSM9DS0 and LSM303C. I can't find any evaluation boards to order for these parts. Can you help me out?Thanks,Ian #lsm9ds0-lsm303c
LSM9DS0 4-wire SPI communication
Posted on October 12, 2013 at 08:27hi,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...
About LPS25H
Posted on February 05, 2014 at 04:07 Hi, Besides, about LPS25HTR, what are the Wake time from power down to �communication ready� and acquisition time in high resolution mode for this chip? I think this chip is very good. Changhong #barom...
