Develop a Gumnut interrupt handler that responds to interrupts from the incremental encoder input of Exercise 8.4. The handler should increment or decrement a value stored in memory as the knob is turned clockwise or counterclockwise, respectively. The value should be limited to the range 0 to 100.

Exercise 8.4

Show how the input controller described in Example 8.13 on page 364 can be used for a volume control knob with an incremental encoder.

Example 8.13

Design an input controller that has 8-bit binary-coded input from a sensor. The value can be read from an 8-bit input register. The controller should interrupt the embedded Gumnut core when the input value changes. The controller is the only interrupt source in the system.
