Slowing Down RGB PWM Routine

[Tissy]

OK, i think i know what you mean, but being new, how do i do that in the code i have. Would you mind giving me an example using my code?

I'm guessing it will use a loop where i call that routine, say ten times and then jump to the next sequences etc.

Many thanks.

That is not so hard let me help ya;

 

main:

for rainbowval = 0 to 255

for a = 1 to 100
gosub rbgrainbow 
next a
next rainbowval
for rainbowval= 255 to 0 step - 1
for a = 1 to 100
gosub rbgrainbow 
next a
next rainbowval

goto main

of course you have to adjust the value's and you have to create the variable "A" (if your gone use high value's create a word size variable)

Edit: you could also let a timer run in the background that keeps sending the pwm signals and change the value's in the mainloop

Hi Tissy,

Since the software PWM command only works while that statement is active. It's going to be difficult to get the LED's to work the way you're wanting.

Take a look at this link
Multiple Slow speed Software PWM

This will allow you to have all 3 PWM's running in the background at the same time. Then you can just cycle thru the PWM levels as needed without worrying about the timing.

Exactly what i meant ......

FOR X = 1 to 10
GOSUB ledpwm
