Controlsystem for compact sporting (clay shooting)

[Fredrick]

Hi

I´m trying to to make a control system for 8 clay throwers for compact sporting.

This is how a compact sporting place can look like.

(We do not shoot whit 6 shooters as in the example)

4.4 Shooting sequence for a round
Shooters position (See Annex 3):
The shooters in the squad go to on the stands in the order set out on the score sheet.
The shooter waits behind stand # 1, is ready to take the shooter’s place, once the
shooter at stand 5 has finished shooting the clays on his/her menu.
The shotgun position is free at the time of calling for the target (at the shoulder or
not).
All the targets must be fired at with the gun at the shoulder.
The shooters fire in turns at each single and double target in the order on the menu.
A time lapse of 10 seconds at most is allowed for each shooter to call for his target
or targets after the shooter at the previous stand has finished firing.
The Referee must announce to the shooter at the station # 1 when it has to shoot.
When the shooter at stand # 5 has finished firing at the targets on his menu:
• He moves to stand # 1 and waits behind it
• The other shooters move to the next stand on their right
• The shooter who was waiting previously takes his place on stand # 1.
It is always the shooter on stand # 1 who starts the round of five targets

The control system I want to make is a box with 2 buttons THROW and REVERSE.
Now we have a big box whit 8 buttons for each thrower and manual push the different combinations for each stand, I want to make this by steep throw a program whit just one button.

I tried to make this whit 20 loops and wait for the throw button to be pressed and just jump to the next loop or back to the previous loop if REVERSE button what pressed.

This works for 5 shooters but I also want to tell the program if the number of shooters for example is only 1, 2, 3, or 4, I will store number of shooters in a variable that is set by the user via a LCD before the game starts (1 to 5 shooters)

If three shooters they will start on stand 1, 2, 3 and after the menu move to 2, 3 and 4 and then to 3, 4, 5 and then to 4, 5, 1 and that last shooting on stand 5, 1, 2.

How do i do that, should I still use 20 different loops and write a lot of IF THEN ELSE within them to decide witch loop that should be the next to jump to?

Or how do I do it in a good way?

My English is not perfect so I hope you understand what I trying to do here.

Do I understand correctly . . . You want to DeSelect the unused stands from automatically throwing the clay? So you would throw in sequence 123, 234, 345, 451, 512 for 3 shooters . . . 1234, 2345, 3451, 4512, 5123 for four shooters . . . ? You should be able to do that using an array and shift the bits over.

[Fredrick]

Yes that´s correct.
How do i do an Array and shift bits, do you have an short example?

Got 1 ready now, incomplete but it serves as example, change the shooters var to change lights lit

@MyConfig = _INTRC_OSC_NOCLKOUT & _WDT_OFF & _PWRTE_ON  
@MyConfig = MyConfig & _MCLRE_ON & _BOR_OFF 
@ __config  MyConfig 
include "modedefs.bas"
DEFINE OSC 4
PortA = 0
PortB = 0
PortC = 0
TRISA = 1
TRISB = 0
TRISC = %00000000
i var word 'locks up @ 255 with byte
ANSEL = 0
ANSELH = 0
CM1CON0 = 0
CM2CON0 = 0
shooters var byte
total var byte
serout PortA.2,t9600,["enter shooters"]
' too lazy to do input routine
shooters = 2

lookup shooters -1,[1,3,7,15,31],total
main:
portc = 0
'pause 200
for i = total  to 255
portC = i
i=i  << 1-1
pause 500
next i
i=0
portC = i
pause 500

goto main
end

not a typical array as we normally see them, but it works using pickit2 & lowpin demo board

Sorry... but I don´t understand how to do the program with the lookup function.

Where comes the numbers [1,3,7,15,31] from and what does it do?

How to i use the lookup to point the program to the right loop that contains the right clay combination?

What does it do . . . It tells your program how many shooters are there, from the input I was too lazy to code for you. You get that input from a key routine or waste 5 ports as inputs, either way you answer the question, how many shooters. I answered it by coding shooters = 2, you I expect will want to select 1 to 5 at will.
The numbers in the lookup table are decimal representations of their binary equivalent. Think of PortC as a 8 digit binary display, 1 would light just bit 0, 3 would light bits.0:1, 7 lights bits 1:3 . . . I urge you to try this code snippet and alter the numbers and see what it does. The lookup table just makes the counter count read differently, when it sees 1 it reports 1, 2 it reports 3, 3 it reports 7 . . . in binary. The -1 in the lookup just makes 0 invalid as you would never have 0 shooters.
