Hi, am working with iks01A1 expansion board (specifically LMS6DS0 sensor) and i need to change the Output data rate, could someone please tell me how ? thank you.

Hi @NAsma.1​ ,

A fast solution could be use the Unicleo-GUI for the IKS01A1 interface and to change the ODR settings there..

For a code-level interaction with the LSM6DS0 device, unfortunately, the X-NUCLEO-IKS01A1 is no longer support by ST. However, you can try to use the X-CUBE-MEMS1 package, and in particular the examples related to the IKS01A2 and the sensor_commands.c

**
 * @brief Set sensor output data rate
 * @param Msg the pointer to the message to be handled
 * @retval 1 if the message is correctly handled, 0 otherwise
 */
static int SC_Set_ODR(TMsg *Msg)
{
 float odr = 0.0f;
 int ret = 1;
 
 ArrayToFloat(&Msg->Data[5], &odr);
 
 /* Sensor Type */
 switch (Msg->Data[4])
 {
 case SC_ACCELEROMETER:
 if (IKS01A2_MOTION_SENSOR_SetOutputDataRate(AccInstance, MOTION_ACCELERO, odr) != BSP_ERROR_NONE)
 {
 return 0;
 }
 break;
 
 case SC_GYROSCOPE:
 if (IKS01A2_MOTION_SENSOR_SetOutputDataRate(GyrInstance, MOTION_GYRO, odr) != BSP_ERROR_NONE)
 {
 return 0;
 }
 break;
 
 case SC_MAGNETOMETER:
 if (IKS01A2_MOTION_SENSOR_SetOutputDataRate(MagInstance, MOTION_MAGNETO, odr) != BSP_ERROR_NONE)
 {
 return 0;
 }
 break;
 
 case SC_TEMPERATURE:
 if (IKS01A2_ENV_SENSOR_SetOutputDataRate(TmpInstance, ENV_TEMPERATURE, odr) != BSP_ERROR_NONE)
 {
 return 0;
 }
 break;
 
 case SC_HUMIDITY:
 if (IKS01A2_ENV_SENSOR_SetOutputDataRate(HumInstance, ENV_HUMIDITY, odr) != BSP_ERROR_NONE)
 {
 return 0;
 }
 break;
 
 case SC_PRESSURE:
 if (IKS01A2_ENV_SENSOR_SetOutputDataRate(PrsInstance, ENV_PRESSURE, odr) != BSP_ERROR_NONE)
 {
 return 0;
 }
 break;
 
 default:
 ret = 0;
 break;
 }

It is not a plug-and-play solution, it has to be adapted to IKS01A1 devices.

Thank you so much,

Is there any way i can recuperate the tilt angles without using the unicleoGUI, a code-level interaction i mean ( since LSM6DS0 provides acceleration and angular velocity ) ?
