FusionFX and quaternions - stationary drift

Hello, I'm using the FusionFX library(V2.5) to calculate quaternions and therefore estimate an object position. I'm using an X-NUCLEO-IKS01A3 that has the  LSM6DSO (ACC + Gyro) and LIS2MDL ( Mag). I'm using an 16G scale in acc and 2000dps in the gro...

Resolved! BMI055 interrupts problems

Hello,I am writing a code to initialize the BMI055 IMU on my STM32F765. To do so I am using the HAL libraries to enable the SPI connection through DMA and the drivers provided by Bosch: bma2x2 and bmg160.The two sensors work perfectly when only one o...
