RBG Component (FC5)
Hi
I've been pulling my hair out trying to get the RGB component on hardware.
The Simulation is fine, but on hardware It always has 2 of the outputs high at any time.
Ive tried various configutations. Ive tried having the tick macro in the main loop and calling it as a seperate macro using various timer interupt settings.
But it still wont cycle the 3 basic colours.

Hi,
I ran it in V5 , using ECIO 40P and using an LED board, so 3 LEDs rather than the 3+common of an RGB. I got the same 'inverted' logic you saw.
Changed the polarity in the componet properties and got the expected bahaviour. But this I guess would only work with a common anode type RGB, I think

Hi Jay Dee

I initally tried it with a comon cathode RGB LED.
I can get it to cycle correctly if I program it by setting the relevant port bits high or low, but not using the component.
I did try it using the LED e-block and got the same results, i.e. 2 leds on at once.

Just tried your suggestion and set it to active low, and its works
Just missed that setting.

Thanks

it is possible to get it to work by calling the tick macro using TMR0 interupt as well
Ive attached a simple test program though the interupt time may need fine tuning to match the application.
