PWM not supported

stafvg · Post by **stafvg** » Tue Jul 10, 2007 9:44 pm

Today I've received my formula flowcode (via elektuur). After problems with the USB-driver, solved with the tip in this forum, I tried the program the robot. I tried a PWM signal as discribed in the user guide buth when I tried to compile the program I got the error message that only certain modules are compiled and PWM was not in the list !!
So how can I program now my robot ?
Must I buy the professional version of flowcode ?
Thanx for any respons.

Hello Staf,

The free version of Flowcode that accompanies the Formula Flowcode buggy does have certain limitations, one of which is the lack of a PWM component.

Here are your options:

1) upgrade to Flowcode pro

2) program the robot without PWM (i.e. turn the motors fully on or fully off)

3) interface to the PWM module in the PICmicro using 'C' or assembly via a 'C' icon

4) create your own PWM-style output

I hope this helps. We can provide a bit of help with the 'C' code if you are not able to program in 'C'.

Hello Staf,

Please see these 2 posts:

With these updates, it should be much easier to program the buggy with all versions of Flowcode - including the free/demo version.
