Timers, PWM and analogWrite

-

can explain why, in attached sketch, works intended (hi, medium, hi, medium...) when "redled" (pin11) in lines 41 , 46 written to?

if change statements in lines 41 , 46 either "greenled" (pin 9) or "blueled" (pin 10), analogwrite statement acts digitalwrite. i.e. pwm less 255 manifests off.

all 3 of these pins labeled pwm pins. timers conflicting pwm? way around this?

thanks help. -scott

pin 11 pwm controlled timer 2.  pwm pins 9 , 10 controlled timer 1. timer 0 affects millis(), micro(), , delay(...).

i guess use of timers 0 , 1 not compatible use of pins 9 , 10 don't understand finer details.

there libraries may out, or choose other pins.

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
