Missing public method accelerometer.whoAmI()

[bobwilmes]

The file microbit-dal/source/drivers/MicroBitAccelerometer.cpp appears to be missing a declaration for the public method accelerometer.whoAmI() as described in the documentation here:
https://lancaster-university.github.io/microbit-docs/ubit/accelerometer/#whoami

I think this is the case. In fact the whoAmI function is not implemented yet. PR #373 was to implement whatAmI.

From https://lancaster-university.github.io/microbit-docs/ubit/accelerometer/
"There are two variants of the micro:bit , one uses the MMA8653 and the other a uses the LSM303 combined accelerometer and magnetometer."

If you need to determine which accelerometer is in use now, as a temporary workaround, you could try using the isDetected functions. These functions make a call to I2C to see what hardware is present, whereas whoAmI/whatAmI would return the previously detected state.

For example,

#include "LSM303Accelerometer.h"
int isLSM303 = LSM303Accelerometer::isDetected(uBit.i2c);

microbit-dal/inc/drivers/MMA8653.h

Line 124 in 9164922

static int isDetected(MicroBitI2C &i2c, uint16_t address = MMA8653_DEFAULT_ADDR);

microbit-dal/inc/drivers/LSM303Accelerometer.h

Line 148 in 9164922

static int isDetected(MicroBitI2C &i2c, uint16_t address = LSM303_A_DEFAULT_ADDR);

microbit-dal/inc/drivers/FXOS8700.h

Line 225 in 9164922

static int isDetected(MicroBitI2C &i2c, uint16_t address = FXOS8700_DEFAULT_ADDR);

Thank you Martin - I tried the work around and it works. Slight nit - on the public class names for the accelerometer - the MMA8653 and the FXOS8700 use class name's based on the device as in
::isDetected.

The LSM303 uses LSM303Accelerometer::isDetected.

Not sure I understand, but yes, we should only need to use functions in MicroBitAccelerometer (ie. uBit.accelerometer). Accessing the device specific class is the only workaround I can see, until whoAmI gets added.
