Vb and stamp Rc time

Hi group:
From: Jimmy
I am building a shiting simulator for a driving school for 18 wheelers I
have got the whole thing working except the analog input I need to monitor 2
analog inputs one for tac and the other clutch to make sure they hit the
friction point each time and to make sure the rpm is not to high or low I am
thinking about using rc time in my code and please bear with me I have a dumb
question if I put this in a loop in the bs2 how can I get the processor to loop
at other loops conditional branch or if then but I need both loops to run
together I realize this processor is not multitasking but this project does not
really need high speed just 2 loops running together any Ideas and thanks for
all your help.Happy stamping. jimmy

Sure hope you mean "shifting" (sorry).
I would think you could use RCTime and just read both inputs, do your
processing, and go again, right? So:
Loop:
do RC #1
do RC #2
do computations
goto loop
I'm not sure if that's the gist of your question or not.

This uses 'TaskID' and the 'BRANCH' statement
to do three 'tasks', then wait 100 mS and do
them all again.
This code can be condensed a little,
(The TaskID cycle can be simplified
using the 'mod' operator) but this
is a general expression.
TaskID VAR BYTE
MaxTask CON 3
TaskID = MaxTask
MAIN:
Do_Important_Stuff
TaskID = TaskID + 1
IF TaskID >= MaxTask THEN Skip1
' ELSE
TaskID = 0
Skip1:
BRANCH TaskID, [noparse][[/noparse]DoTask1, DoTask2, DoTask3]
' DoTask1 'GOTO' when TaskID == 0
MainContinue:
IF TaskID = (MaxTask-1) THEN Main ' do three rapidly
PAUSE 100 ' THEN pause...
GOTO MAIN
' Tasks...
DoTask1:
Do_Stuff

I don't have to direct my tasks back to another label -- the return is
handled by the GOSUB. And, by structuring tasks as subroutines, they
can be called from any point in the program; even from each other if the
situation warrants.
MaxTask CON 3
taskID VAR Byte
Main:
Do_Important_Stuff
ON taskID GOSUB Task0, Task1, Task2
task = task + 1 // MaxTask ' point to next task;
auto wrap to zero
GOTO Main
Task0:
Do_Task_Stuff
RETURN
Task1:
Do_Task_Stuff
RETURN
Task2:
Do_Task_Stuff
RETURN
This is a fairly simple structure. If we move the taskID update to the
task code, the program can be much more dynamic in it's operation --
this is particularly useful in robotics.
MaxTask CON 3
taskID VAR Byte
Main:
Do_Important_Stuff
ON taskID GOSUB Task0, Task1, Task2
GOTO Main
Task0:
Do_Task_Stuff
IF (some_condition) THEN
taskID = new_task ' run conditional next
task
ELSE
task = task + 1 // MaxTask ' run *normal* next task
ENDIF
RETURN
Task1:
Do_Task_Stuff
IF (some_condition) THEN
taskID = new_task
ELSE
task = task + 1 // MaxTask
ENDIF
RETURN
Task2:
Do_Task_Stuff
IF (some_condition) THEN
taskID = new_task
ELSE
task = task + 1 // MaxTask
ENDIF
RETURN

The only reason I would use the
'BRANCH' version is that it is 'native'
2.0 PBasic. Once the 2.5 PBasic becomes an
'alpha' version, I'll use it. Even then,
there's a lot of 2.0 code out there.
And your point about changing/incrementing
the 'TaskID' state variable inside the Tasks
does give you lots of flexibility with
how often tasks repeat, or what task runs
next. I would use it sparingly, though,
or you'll have the 'spagetti' factor --
it becomes hard to know what SHOULD
execute next -- which becomes hard to debug.
