BHI160B : bhy_get_physical_sensor_status(&accel_status, &gyro_status, &mag_status)

[Eyalb]

I use BHI160B.

I call bhy_get_physical_sensor_status(&accel_status, &gyro_status, &mag_status) and get all parameters zero value.

other than that I have gyro example working, but I want to know which dynamic range value is set after I called :

bhy_enable_virtual_sensor(VS_TYPE_GYROSCOPE, VS_WAKEUP, sample_range, 0, VS_FLUSH_NONE, 0, dynamic_range);

this because I want my computation to be right : float_tmp = pi_const * (sensor_data->data_vector.x) * dynamic_range / 32768 / 180 ;

thanks.

Hello Eyalb,

Before you call sensor API, have you finished sensor initialization?

By the way, which example code you used?

hello.

Yes. I finished sensor init  and then called func to get parameters.

I use this code :

bhy_driver_init(&bhy_fw);

semTake(imuSem,WAIT_FOREVER);

if(bhy_install_sensor_callback(VS_TYPE_GYROSCOPE, VS_WAKEUP, sensors_callback))
{
DEBUG("Fail to install VS_TYPE_GYROSCOPE callback\n");
return;
}
/* enables the virtual sensors : */
if (bhy_enable_virtual_sensor(VS_TYPE_GYROSCOPE, VS_WAKEUP, sample_range, 0, VS_FLUSH_NONE, 0, 0/*dynamic_range*/))
{
DEBUG("==========================Fail to enable sensor id=%d==================================\n", VS_TYPE_GYROSCOPE);
return;
}
if (!( bhy_get_physical_sensor_status(&accel_status, &gyro_status, &mag_status)))
{
dynamic_range = gyro_status.gyro_dynamic_range;
DEBUG("read dynamic_range. value is : %d \n",dynamic_range);
}
else
DEBUG("error read dynamic_range. \n");

while(1) {

semTake(imuSem,WAIT_FOREVER);
/*while (!ioport_get_pin_level(BHY_INT) && !bytes_remaining);*/
bhy_read_fifo(fifo + bytes_left_in_fifo, FIFO_SIZE - bytes_left_in_fifo, &bytes_read, &bytes_remaining);

...... 

thanks.

Hello Eyalb,

There was a example in github to read sensor status, could you test it on your platform?

I'll test it ASAP. thanks.
