Wow! Thanks for taking the time to write the code. I just had time to run it on my robot and it ramped up and down nicely in both directions. Will have time later today to study the code and learn. Now that I have got motor control I can move on to the ping code and make it roam safely around.
I don't technically have a Stingray either had to build my own and I'm calling it "Banshee". I've put all my plans up on the forum I posted above. Maybe you could build one for your self. More than glad to help if you have any questions.
Thanks for the update! Works as smooth as silk. Will be working with the pings using the program in the Demos for a start. I will post the code as I get it developed for running on three pings and ultimately roaming on pings.
EDIT: Solved it. Changed multiplier in Ping task from 10_000 to 1_000 works good. Updated file for those who may be interested in looking at the code.
EDIT2: Changed 1_000 to 500 to remove the out bound trip of ping sensor. Updated file for those who may be interested in looking at the code.
Could you look at this code for me and help me see why when the pings task writes to the distance hub variable it isn't being passed or read in the main loop. In other words wheels spin, ping works but when I move my hand within 12 inches of the ping it does not stop the wheels.

Use BASIC on the Propeller with the speed of assembly language.
I just wanted to report, that I have worked with PropBasic some more hours and everything was working completely stable. I can now use LMM, for my user interface, totally stable too, only my own bugs....
One question, constants cannot be used in DATA, is this true?
And another question. I know, some people will be shocked, that someone is even thinking about it. What do you think about (single) float maths? Together with LMM it should be possible, I think? I do use float sometimes with BASCOM, where it is very easy·and have allways missed·a seamless possibility in spin. Yes, I know, everything can be done with integer maths, but float makes life easier sometimes....
DEVICE P8X32A, XTAL1, PLL16X
XIN 6_000_000
LED PIN 27 OUTPUT
LEDX TASK
Start:
COGSTART LEDX
Main:
GOTO Main
END
TASK LEDX
'LED PIN 27 OUTPUT
DO
LED =0
pause 1000
LED =1
pause 1000
LOOP
ENDTASK
When I run above program led does not flash, however if I define LED in Task LEDX only it works fine.In the first case LEDX appears to define the pin as an input(according to spin file produced) and in second case it defines it correctly as an output pin.
I understood PIN could be defined at start of program and that it was not necessary to define in each task ??
Gerry
Pin masks are in fact global but, for the moment, anyway, each task has its own DIRA setup. What this means is you have to tell the task that the LED pin is an output -- you can do it like this:
TASK Flasher
OUTPUT #LED
DO
LED = 1
PAUSE 500
LED = 0
PAUSE 500
LOOP
ENDTASK
Doing this allows your top level program to define the pin # for an output in the event you are controlling it from two cogs (main and task cog).

Gerry,
Yes, what Jon said. The PIN modifier is only for the current TASK (or the main code).
If you made a pin an output in all tasks you would not be able to control it. If ANY task made it high, it would be stuck high. Also if you wanted to make it an input later in your code you couldn't because other TASKs would still have it as an output.

I'm sure our questions will get answered no matter where we post, but in general: should propbasic questions/issues/requests·be directed only to this thread, or should we start (or is it okay) making new threads, maybe with a "Propbasic: Topic"
It just seems like this thread is awfully long to me, ·but can understand up until a point.· Then again, it may be·simplier for Bean, Jon, (et al).

Do I understand that only one file is needed for PropBasic or only one file is being updated? I am confused over your post about propcide not beinig used.

This does get updated more often at the moment as I'm in the throes of some additions/improvements and of course lots of bug fixes.
It happens in fits and starts. There might be no updates for a month, and then I get some time to work on it and you might get 4 in a day.
It is not required to update every time there is a pre-release posted, but it is recommended to be running the latest release code (0.19.3 at the moment)

You only ever need two tools in life. If it moves and it shouldn't use Duct Tape. If it does not move and it should use WD40.
Worked up this code to help another individual on another post. The code controls 6 servos (4 standard and 2 continuous rotational) using three Cogs. The code was ran on Propeller Robot Controller Board.
I know it is way simple so don't laugh to hard, but I thought it my help some other beginners with PropBASIC. That's why I did it in the first place and it was great practice writing code in PropBASIC.
Tony,
Thanks for posting that code. One comment... It really doesn't make sense to create a custom Delay subroutine for 2 uses. It's just my opinion, but I think it makes the code alot more complecated than it has to be.
If you have BIG programs, then yes it pays to create subroutines. But for 2 calls...No...For short programs...No.
As a teaching tool it DOES show how to use subroutines so that is a benefit.

Yeah, I could see in the webserver logs people were still constantly downloading old versions with known unpleasant bugs, so I moved them. It had not occurred to me people would link to specific versions.
I posted my newest robot "4 Paws" on the robotics forum which is running on a Propeller chip and PropBASIC of course. I plan to use PropBASIC on all my Propeller projects. http://forums.parallax.com/showthread.php?p=894042
Don't laugh to loud at the code. I'm still learning and it is only testing code. I hope by the time I'm done with 4 Paws I will be at least an intermediate programmer in PropBASIC.
I haven't given up on the Banshee robot. I’m still trying to come up with the code to read three pings and control motor speed and direction. It’s a little harder than I thought.
A new release of PropBASIC should be available shortly.
Version 00.00.88 fixes the following problems:
FIXED: "DO WHILE|UNTIL pin =|<> value" performed opposite condition
FIXED: "DO WHILE|UNTIL pin =|<> var" caused error
FIXED: If pin group starts at 0, omit "shr xxx,#0" instruction
FIXED: "IF P0 = P1 THEN"
FIXED: Added INIT and __INIT to INVALID.TXT
FIXED: subtracting a defined long constant performed an add instead of a subtraction
FIXED: Allow pin group as right side expression for DO and LOOP
FIXED: Allow pin group as right side expression for IF...THEN
New features:
LMM support - Create Large Memory Model code for PROGRAM and TASKs
RDSBYTE, RDSWORD - Reads a signed value from hub memory
name TASK AUTO - Task starts automatically BEFORE main code
Multiline comments - Curly brackets can be used to create multi-line comments
__RAM - Virtual array to access COG ram by address
FOR..NEXT - Uses step -1 if start is greater than limit
STR - Destination can be HUB or DATA string
As soon as BradC has time to post it on his website it will be available.
