Hi andrew,

Do you want to measure the frequency/duty of an external signal ?

I remembre that there is an example provided by ST that shows how to measure signal frequency.

Herzlich,

Yes I want measure frequency/duty of an external signal (from two external sources).

I heard that I can do so by using the PWM input mode for a timer 1 or 2.

But I can not write this in the software.

Can You help me in this case...

I can not find the example. Can you show me the example?

Is it in Application Note?

Hi arkar,

You can download the ST library from the link below:

http://www.st.com/stonline/stappl/resourceSelector/app?page=resourceSelector&doctype=FIRMWARE&FamilyID=141

The name is ''ARM based 32-bit MCU STM32F1xx standard peripheral library''

The example is located in:

STM32F10x_StdPeriph_Lib_V3.4.0/Project/STM32F10x_StdPeriph_Examples/TIM/PWM_Input

Good luck,

Herzlich,
