How to configure acceleration range of Nicla Sense ME (BHI260AP)?

[chinoramas]

Hi,

I have a nicla sense ME IMU sensor and I want to evaluate the various sensitivity range of the accelerometer?

Does anyone have an idea how to change the acceleration range parameter in Arduino?

Or any sample code that I can refer to?

I tried to search and found something but still, I cannot get it how to implement it on the program.

Thank you

Regards

Hi 

This has actually already been implemented, you could refer to the: 

https://github.com/arduino/nicla-sense-me-fw/blob/main/Arduino_BHY2/src/BoschSensortec.cpp

BoschSensortec::configureSensorRange() invokes the API: bhy2_set_virt_sensor_range() to change the dynamic range.

you could refer to the datasheet  section 13.2.8  for more details such as the units of the range. 

Let me know if this helps and / or if you have additonal questions. 

void BoschSensortec::getSensorConfiguration(uint8_t id, SensorConfig& virt_sensor_conf)

gets the configuration (incl. the dynamic range) of the sensor.

Where do I put this command into? Ignore my stupidity, I'm pretty new to this stuff, trying to do a school project.

Hi Jbarton

no worries. 

you could try this, e.g.:

in the example sketch: https://github.com/arduino/nicla-sense-me-fw/blob/main/Arduino_BHY2/examples/Standalone/Standalone.i...

you could add a line, 

void setup()
{
Serial.begin(115200);
while(!Serial);

BHY2.begin();

accel.begin();

accel.setRange(16);  // this is an example, you might need to change this to 4, 8 or 16 based on your needs
gyro.begin();
temp.begin();
gas.begin();
rotation.begin();
}

BTW, there is a new PR on the github which adds a new example on how to read and reconfigure the range of the IMU on Nicla Sense.

Please check the details here:

https://github.com/arduino/nicla-sense-me-fw/pull/65/commits/9c6858f55613c9ee8944aba8e47c8a79a63ba5b...

you could find a new sketch which does exactly that.

Thank you for your  solution. Is there any way to set range from Host side? for example, i read nicla sensor data from portenta h7 by BHY2_Host libra, but there isn't any function to set range
