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...

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.

Hi andrew,

There is an example provided by ST that shows how to measure signal frequency.

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,
