Hi Matrix Team,
When I'm using PWM function, I face build error while compiling hex with ATMEGA128 MCU . Attached is the error report. I'm facing this compiling error only if I used PWM function with ATMEGA128 MCU. Do I need to declare any function? Can you please guide me to resolve this issues?

Hello,

Thanks for letting us know. I've hopefully now fixed the problem and pushed the change to the v8 update system.

Let us know how you get on.

HI Benj,
Thank you very much. Now PWM is working with ATMEGA128 . But I cannot control the frequency and Duty cycle. I'm not sure whether I may made some mistakes in my program. Please find the attached code and Logic analyzer's PWM data. Please guide me. Thanks

Hello,

If you look at the compiler messages then you should see this line.

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"

In your loop you are calling ChangePeriod but as the warning message states the device does not have the period register and so it cannot be altered. Maybe try a different PWM channel as the other channels seem more standard.

Dear Benj,
Thanks. It is working fine now. i didn't see the warning message.
