Declare timer variables
· TrackTimer will manage how often we run stepper tracking
· GameTimer will manage how long we have to make a selection
· LeftToggleDebounceTimer will manage debounce timing of the left toggle button.
· RightToggleDebounceTimer will manage debounce timing of the right toggle button.
· SoundPlayTimer will monitor how long the sound should have been played so we can turn it off early.
· GameTimerLED will manage the timing of the countdown Game Timer LED's.
Declare other variables:
· CurrentTime will be used for performing timer logic
· leftlatch will be used for running code only once per button push
· rightlatch will be used for running code only once per button push
· InitReturn will be used for evaluating whether the Analog library was configured correctly.
· EncoderResult is used for evaluating where the penny dropped.
Initialize Timer variables
Set TrackTimer.Delay to 7 = 14ms.
Set LeftToggleDebounceTimer.Delay and RightToggleDebounceTimer.Delay to 25 = 50ms.
The Sound plays for approximately 20seconds. Set SoundPlayTimer.Delay<20 seconds so we don't retrigger it. 9500=19seconds.
Set GameTimer.Delay to 14000=28seconds
Set GameTimerLED.Delay to 1666=3.333 seconds
Initialize IO variables
Configure the coin sensor input at port M, bit 4.
Configure the drop button input at port AD, bit 5.
Configure the left toggle button input at port E, bit 0.
Configure the right toggle button input at port E, bit 1.
Configure the sound play output at port T, bit 0.
Configure the right limit switch input at port T, bit 3.
Configure the left limit switch input at port T, bit 2.
Configure the stepper outputs at port T, bits 4-7.
Configure the encoder inputs at port AD, bits 1-4.
Configure the swag open output at port M, bit 2.
Configure the swag closeoutput at port M, bit 3.
Configure the prize LED clock output at port M, bit 0.
Configure the prize LED data output at port M, bit 0.
Configure the game timer LED clock output at port AD, bit 6.
Configure the game timer LED data output at port AD, bit 7.
Initialize libraries
Initialize analog library so that pin AD0 is analog, AD1-AD5 is input, AD6-AD7 is output.
Initialize TIMERS12 library.
Initialize Stepper library.
Initialize Swag library.
Initialize PrizeLED libary.
Initialize GameTimerLED library.
Begin Game Code
Repeat
Set Playsound output high.
Reset Stepper to right limit switch
Reset prize LEDs
Reset game timer LEDs
Wait for coin sensor to see the coin
Reset prize LEDs
Reset game timer LEDs
Play Sound
Wait 200 ms to allow coin to fully fall into dropper before proceeding
Set sound play output high after it is triggered.
Reset timers to current time
· TrackTimer
· GameTimer
· SoundPlayTimer
· GameTimerLED
Begin non-blocking loop. All code within may not use Wait().
While the drop button is not depressed
Set CurrentTime equal to the current time using TMRS12_GetTime()
If the tracking timer has expired
Execute stepper tracking
Update the timer with CurrentTime
If the GameTimerLED timer has expired
Count down on the LED's by 1
Update the timer with CurrentTime
If the GameTimer timer has expired
Leave this while loop.
If the Left toggle button is not pushed
Update the LeftToggleDebounceTimer with CurrentTime.
Reset leftlatch.
Otherwise, if it is being pushed
If the LeftToggleDebounceTimer has expired and leftlatch is reset
Shift the prize LEDs left one slot.
set leftlatch to prevent running this if statement from running more than once per button push
If the right toggle button is not pushed
Update the RightToggleDebounceTimer with CurrentTime.
Reset rightlatch
Otherwise, if it is being pushed
If the RightToggleDebounceTimer has expired and rightlatch is reset
Shift the prize LEDs right one slot.
Set rightlatch to prevent running this if statement from running more than once per button push
If Sound Timer hasn’t reached 20s (sound still playing)
Trigger the sound play output to stop the sound.
Wait 100 ms
Set the sound play output high.
Repeat CheckSlot until see the penny pass through one of the bottom Slot
If this is one of the winning slots
Drop Swag
Forever
