Pwm not work

[Serhii]

Hi everyone. There is a problem with compiling the program with the PWM element. Returns lines:
D:\Projects\TRIMMI~1>"C:\PROGRA~2\Flowcode\Common\COMPIL~1\avr\BATCHF~1\..\bin\avr-gcc.exe" -mmcu=atmega328p -Os -ffunction-sections -fdata-sections -funsigned-char -o "D:\Projects\TRIMMI~1\Flowcode1.elf" "D:\Projects\TRIMMI~1\Flowcode1.c" -lm -Wl,-gc-sections
In file included from C:\ProgramData\MatrixTSL\FlowcodeV8\CAL\includes.c:561,
from D:\Projects\TRIMMI~1\Flowcode1.c:249:
C:\ProgramData\MatrixTSL\FlowcodeV8\CAL\/AVR\AVR_CAL_PWM.c:110:5: warning: #warning "PWM Channel Uses Resource Timer 0"
C:\ProgramData\MatrixTSL\FlowcodeV8\CAL\/AVR\AVR_CAL_PWM.c:495:3: warning: #warning "Period control register not available on target device, period will default to 255 + 1"
What is wrong ?

Hi Serhii,
Please post a copy of your program and details of hardware etc

Hi Martin. I use chip ATMega 328p (Arduino UNO and Arduino nano). However, as I read in the file CAL_AVR_PWM this chip is not used in it, but only XMEGA and Tiny. Could that be a problem?

Timer 0 is an 8 bit timer.

Using Timer1 (choose a different channel) allows alteration and compiles ok. It may be a bug or it may be because Timer 0 is used for delay timing purposes.

Hello,

C:\ProgramData\MatrixTSL\FlowcodeV8\CAL\/AVR\AVR_CAL_PWM.c:110:5: warning: #warning "PWM Channel Uses Resource Timer 0"
C:\ProgramData\MatrixTSL\FlowcodeV8\CAL\/AVR\AVR_CAL_PWM.c:495:3: warning: #warning "Period control register not available on target device, period will default to 255 + 1"
What is wrong ?

Nothing wrong just a warning that if you try and change the period using the PWM properties or the ChangePeriod component macro that it won't do anything as the "Period control register not available on target device" and the "period will default to 255 + 1"

Basically the channel you have selected uses a timer that doesn't support variable periods. Other channels using other timers will work fine.

Ok Benj, I will try it in the device.

Hi Benj. All right, I don't understand why the PWM initially refused to work, may not be the correct parameters set and the warning scared me? Don't know, but now everything works as it should)) Thanks for the help. Have a nice day!
