Robotc if else code#

In the state STOPPED, the code checks if Start is pressed if it is, the new state becomes ACCEL. Two states can be added, ACCEL and DECEL. Now, imagine that the motor has to do ramp-up and ramp-down. Motor = Knob // rotate with the speed given by Knob Motor, Knob, Start and Stop all are I/Os that another thread care to read or set. This machine has two states: STOPPED and RUNNING. When you press STOP, the motor stops (until START is pressed again). When you press START, the motor turns with the speed set by the knob. Suppose you have a motor, a start button, a stop button, and a knob to set the speed of the motor. Among the checked inputs, one of them can trigger a state change. The transition from one state to another is conceptually separated, but often is performed by the same code: this way, in some state a set of inputs can be checked (and other ignored), and in another state a different set of inputs can be checked. In a finite state machine, for every different STATE, the machine carries out a certain set of operations. The order of IF and SWITCH statements is not important in the OP example. You need to give reading a way to get a value. Of course, keep in mind that in the way you have written your code right now, reading cannot receive any input. Then, in the switch statement your SystemState variable would always be State1. Taken in from external sensors in real time Suppose that you had if and switch statements the opposite way, like this : task main() So the correct order is to have your if statement, so that SystemState variable takes the desired value, and then examine the value of SystemState in your switch statement. Your switch statement examines the value of the SystemState variable, which is set through your if statement. Can't wrap my head around the order of my 'Switch' and 'if' statements (which should come first).
