need help with a program

stilgar

Hello,
I am having trouble with a program from the object exchange by Colin Fox.
The program "led_pwm v1.0 "

When I try to use more than 8 LEDs, the program stops.
Is there a variable I need to change to fix this?

Also my finished project needs to run 32 LEDs, BUT, I only have 20 pins to use for the LEDs. the others are for sensors and sound.
Any points to figure this out?

thanks,
stilgar

The delay (600) is too short for more than 8 LEDs (with decay it basically traps in a just missed waitcnt). Try bigger values, e.g. 1200 for 16 LEDs.

I can not find where the delay at 600 is? the clock settings often gets me confused. Could you direct me to the line in question? and maybe a corrected line?

I believe he is referring to

delay long 600

which represents: variable name/variable data type/variable initial value

at the bottom of lm_pwm_1.spin in the DAT section

Found it, and that was the problem.
Thank you,

Don't thank me, thank Kuroneko ; )

Pity we don't have a Kuroneko to identify the bugs in government programs.
