Found the problem!

This PC had an old version installed. Although I used the add/remove software option, obviously it didn't do the job properly. Only now, after installing to a different folder, is the new version of the software running.

Hi,

I would like to do a demo of the formula flowcode buggy tomorrow at an open day. Is there a demo version of flowcode that contains the buggy modules. When I load the test examples provided, I get a warning that the demo is written in a newer version.

Also the formula flowcode component is ...

Thnaks Ben,

Will do.

Dave

Hi Ben,

Looks like that may be the problem! :lol:

Thanks Ben. I had already attached the board to the chassis before I made the electrical connections. When the board is the correct way up, the cross over doesn't happen - the left connection is above the left motor etc. :shock:

I either didn't ...

Odd now!

For some reason, the "reverse" component is now working - forwards!

I put a meter over the pins of the motors whilst in "forwards" mode (200) and the meter was reporting a voltage of -1.99v - I guess thats why the motors are running backwards, but it doesn't explain why the other ...

Just seen that you can save the flowcaode as a JPG, so that's a start I guess.

Dave

Thanks Steve,

I will send the file as requested.

Just as a thought, is there a way to see the flowcode "code" in text form, for posting examples here for example.

Dave

Sorry about the photo focus - think you can see that the connections are correct...

Hi,

I have been tinkering with the new components. A simple routine I wrote was like this...

Delay 1s
LEDOn 0
WaitForSwitch 1
WriteLEDs = 0

When this is downloaded, I expect that after 1 second, the first LED should light until I press the button.

After programing, after the 1 second, I get a ...

Well done everyone, brilliant components.

Very useful examples,

Many thanks,

Dave

Hi Ben,

Well done to you all for the new components for the Buggy. The components and test routines are fantastic.

Right, I still have the same problem with the buggy using the new components. Assuming the line-following circuit is at the "front" of the buggy, then...

"Forwards" component makes ...

Hi Ben,

I'm looking forward to it, and quite undestand that these things do indeed take time!

Many thanks

We are keeping you on your toes!!!!

At least it shows we are interested in the product!!!

Hi,

I've used the example flowcode to get the buggy moving with PWM - in reverse (assuming the line following module is at the "front"), but not forwards.

Also, using the turn example, the buggy turns with one motor stopped, and one turning instead of them going opposite directions, so again, the ...

Hi,

Having read Ben's instructions, I am now a little confused about the table of speeds at the bottom of the article.

I understand with PWM, a set voltage is applied to the motor for a set period of time, and then switched off for a period of time. By switching the power on and off with different ...

Thanks Steve,

I think you are right about the registry key - this may be of use for others.

I will sort out the PWM, but will raise it as a separate post, as it is not to do with this thread.

Cheers,

Dave

OK, Flowcode and PPP re-installed, and all seems to be working fine!

Now just got to get my head round PWM, but thats another matter!!!!

Thanks for all your help,

Dave

Hi Steve - stop looking!!!!

OK, what I did was this....

Uninstalled ALL flowcode software that had been installed. Rebooted the laptop.

Installed the drivers from the version on your website.

Rebooted the Laptop

Checked in the registry, and the RunOnce key was missing from HKEY_LOCAL_MACHINE ...

Thanks Steve.

I unplugged the buggy, booted the laptop from scratch, and installed the software directly from the installer in the ZIP file.

I then plugged in the buggy, and selected Automatic install when asked. At the end of the install, the following message appears ...

Hi Ben,

I think these were the drivers I tried. Anyway, no luck. :cry:

Same problem, the install of the drivers ends with an error, and that’s why the whole thing starts up again.

I have just plugged the FF buggy into a newer laptop with USB2, and it all installed ok from the drivers you ...

Hi,

I am having troubles installing the buggy on a laptop with USB1 not USB2.

I plug the buggy in, LED RD0 and RD1 both flash together, and the new hardware detection wizard starts after a bubble pops up saying Found New Hardware Formula Flowcode Buggy

I try to install the usb driver either from ...

Hi Ben,

I installed the full version of flowcode to get the pwm working. When trying to compile your code, it complained the the pwm models was missing, even though I bought the full version only last week. Think it was 3.1xxx

I downloaded the newest version, and the complier is now happy with the ...

Hi,

I too had problems with a loose battery, but as noted, I bent the terminal out a bit to get a better spring action.

I have used this type of chassis before, and you also have to watch out for the joining steel wire (between the 2 battery packs) as it wasn't soldered to the battery contacts in ...

Thanks Ben,

That should get things moving!!!!

Dave

Thanks John and Steve,

I am trying to use the flowcode for the first time. Its very exciting.

New to Flowcode and the buggy, there is a huge "learning curve" as they say - even to the extent of knowing where to look for information.

The penny dropped last night as I was on this forum, that the ...
