///
/// Read analog values into `buf` at a rate set by the `timer` object.
///
/// `buf` can be bytearray or array.array for example.  The ADC values have
/// 12-bit resolution and are stored directly into `buf` if its element size is
/// 16 bits or greater.  If `buf` has only 8-bit elements (eg a bytearray) then

/// triggers.  The timer must already be initialised and running at the desired
/// sampling frequency.
///
/// To support previous behaviour of this function, `timer` can also be an
/// integer which specifies the frequency (in Hz) to sample at.  In this case
/// Timer(6) will be automatically configured to run at the given frequency.
///
/// Example using a Timer object (preferred way):
///
///     adc = pyb.ADC(pyb.Pin.board.X19)    # create an ADC on pin X19
///     tim = pyb.Timer(6, freq=10)         # create a timer running at 10Hz
///     buf = bytearray(100)                # creat a buffer to store the samples
///     adc.read_timed(buf, tim)            # sample 100 values, taking 10s

///
///     adc = pyb.ADC(pyb.Pin.board.X19)    # create an ADC on pin X19
