Scale and Offset
Scale and offset were introduced in Chapter 3 for managing input values from the
accelerometer. In Chapter 3, we used the
operator for scaling (multiplying) by
**
fractional values. In this example, we'll just use the
operator because a variable in the
*
next example program only needs to be multiplied by the integer value 2.
Take a look at Figure 5-3, where a graph with both positive and negative axes has been
printed in the Debug Terminal. The horizontal, or x, axis has a space between each
numeral, and the vertical, y, axis does not. In order to position the cursor in a particular
spot using the
command, we’ll need mapping between the axes printed in the
CRSRXY
Debug Terminal and the axes used by the
command.
