Example 2: Reading acceleration data from BMA456 (example: low power mode)

-setting data processing parameters (power, bandwidth, range) and reading sensor data

Further steps:

The BMA456 has many more capabilities that are described in this document and include FIFO, power

saving modes, synchronization capabilities with host processor, data synchronization and integration

with third party sensors, many interrupts generation and more features like step counter, etc.

End

start

enable acquisiton of acceleration data.

disable the auxiliary interface

write_reg(addr=0x7D,val=0x04)

disable the acc_perf_mode bit;

Set acc_bwp to 2 repetitions;

set acc_odr to 50 Hz

write_reg(addr=0x40,val=0x17)

enable the adv_power_save bit;

leave the fifo_self_wakeup enabled

write_reg(addr=0x7C,val=0x03)

read sensor data

accel_data[]=burst_read(addr=0x12, bytes=6)

Wait until the first data come

Wait for the DRDY interrupt is triggered
