TMP0 and center aligned PWM

miroslavmartise — Tue, 14 Mar 2017 15:51:45 GMT

Hello everybody,

I am playing with FRDM-KL25Z at the moment, namely with Init_TMP component and blue LED. If I want to set up the mode of channels as a Center-aligned PWM, output signal is not produced farther away. But if I change it to Edge-aligned PWM, it works fine and LED lights.

In attachment you can see screenshot of my current setting.

Is there any bug, or so? This puzzles me.....

Thank you.

Hello Alice,

in attached .rar file you can find my project. It should be noted that I am not the author of entire project, main structure was downloaded from this community forum. I have only changed setting of TPM0 to center-aligned PWM.....

Have a nice day,

Miroslav

Hello Miroslav,

I test your project on my side , find there is a bug in the generated code of Init_TPM.

Please add these code in the file of "TPM0.C"

 TPM0_C0SC = (TPM_CnSC_MSB_MASK | TPM_CnSC_ELSB_MASK);‍‍‍

and disable the original code of TPM0_C0SC :

After change the code, please choose " Don't Write Generated Component Modules":

Then build , run ...

I also attached the project which I changed .

Hope it helps

Have a great day,
Alice Yang

Hi Alice,

I would like to thank you for your advice and help.I highly appreciate it. Center-aligned PWM is working properly at the moment :-)

Have a nice day.
