1/8 2007 C Programming For FIRST FRC Competitions Keith M. Hughes 1/8 2007 easyC Pro come with lots of examples and tutorials. Look at them with copies of these slides by your side and you will see how it all fits together. DONT PANIC! 1/8 2007 Programming. Who Needs It? Every team will most likely need some programming. It is necessary to connect the controls on the Operator Interface to the motors, relays, etc,  on the robot. Autonomous mode requires the most programming, though it doesnt necessarily have to be that sophisticated. 1/8 2007 Warning Dont wait on understanding the programming or thinking about it until towards the end of the build season. The programmers need to be involved early on with the planning for hardware since they have to write programs for the sensors,  because they have to think about what can and cannot be done in software. This means the programmers need to understand programming sooner than later. 1/8 2007 What Well Cover The basics of the C programming language. I am not telling you everything as I am trying to keep this a short introduction. Experienced C programmers will notice that some things I am saying have to happen dont always have to, but it takes too long to explain everything. 1/8 2007 Variables Variables are named bits of memory in the processor. You use variables to keep bits of computations that you have done or to control the robot. pwm1 = p1_x; pwm2 = 255 - p1_y; speedLeftMotor = GetAnalogValue (3) * 2; speedRightMotor = speedLeftMotor / 2; The variables above are pwm1, p1_x, pwm2, p1_y, speedLeftMotor, and speedRightMotor. 1/8 2007 Variables Variables in C must be given a type. The type says what kind of information can be stored in the variable. The type for a variable is given in a variable declaration. unsigned char speedLeftMotor; int leftWheelCounts; The underlined parts are the type of the variabl ...
