Hello there, I'm using a BMX0155 sensor connected to a STM32 thanks a SPI Bus. I've already implemented High-G interrupt for the accelerometer (IT is genererated when Accel X value is > 0.150g) and it works perfectly. After this implementation i tried to do the same thing for the gyroscope but without succes, here is some code : (a) Gyroscope register values : (b) Gyroscope Interrupt register values : So first, I  configure the right port the same way as i configured accelerometer IT port Then, I set GYRO registers with values of picture (a). Then I set IT GYRO registers with values of picture (b). finally i enable the right IT (high_en_z (bit 0) of 0x26 register is set) The fact is that the interrupt is generated (high_int (GYR 0x09) status flag is set and high_first_z (GYR 0x0C) is set too)... ... but i can't catch this IT with the STM32. Did i miss something with IT gyro configuration ? Thanks Regards ... View more

Hi everyone, I'm using a BMX055 (connected to a STM32) but i'm a little bit lost with acceleration values read. I think that my BMX is well configured (you can check the picture that i've attached) and i read these raw values : acc_x = 4094 acc_y = 4092 acc_z = 250 are these values in two’s-complement format ? or can i directly convert these values into g (acc_x_g = 1g = 4094*8/32767 = acc_y_g and acc_z = 0.06g), it should be 0 g for x and y axis and 1g for z right ? Also, i try to understand what is the bias accelorometer value but i'm not sure of what i've done : i've read 100 times the acc_x/y/z values then i get an average and i store the result into offset_xy/z registers. But the fact is these registers are only 8bit registers. Are the offset_x/y/z register values atutomatically substracted from x/y/z data registers when we read them ? Thanks for your help Regards   ... View more
