The fact that the state machine based firmware always returns to the same point in the
code also makes the firmware easier to debug. When a bug is encountered, set a break
point at the jump station. Then, step through the program state by state until the bug is
found. An example of a bug would be the SV being modified incorrectly in one of the
states. If this happens, the wrong state will be called the next time the program flow
returns to the jump station. However, because the SV is being monitored, it will be very
easy to see when an unintentional change is made to the SV and in which state the SV
was incorrectly modified.
Note:
MPLAB IDE contains a built-in simulator. See the MPLAB IDE v6.xx Quick
Start Guide available on the MPLAB IDE CD-ROM included with the
PICkit 1 Flash Starter Kit
Another benefit of state machines is that it naturally promotes modular code. Modular
code has its own list of benefits:
1. Upgrades and special features can be easily added to the code in later revisions
or as a product evolves.
2. Modules can be cut and pasted into other applications quickly and easily.
3. Other developers will be able to understand the code in order to support it. The
jump station, if commented well, can be an index to each of the software
modules.

Implementation
GENERAL THOUGHT PROCESS
When implementing a FSM, first brainstorm all the states needed to complete a partic-
ular application. Once this is done, identify the first state. Next, the following question
should be answered: “What needs to happen to exit this state, and what state will it exit
to?” Usually there is more than one answer to this question. Depending on what hap-
pens while in a particular state, the state machine may advance a state, decrement a
state or skip several states entirely. As mentioned before, it is generally a good idea to
visually construct the state machine in the form of a flowchart. Finally, create a software
module for each of the states and tie them together according to the flowchart just
created.
