Hello everybody,
since two days I struggle with curious noises at Pin 6 (TQFP32) by STM32F051K8. In my application I try to start TIM2 with TIM14 in kaskade mode (I have slight changed the sample code). I attach my source and screenshots with the signals. On the screen you can see signal of TIM14 (yellow) Pin 10 and signal with noises of TIM2 Pin 6 (blue). Has anyone any idea what's wrong? Thanks in advance! #stm32f051 #tim2 #tim142016-09-28 01:43 PM
and here is the source code ...

Hi richter.andrey,
The TIM2_CH1 is on PA0 and not on PA6. Verify that you put the measure point on the right place , and GND is connected. Fothe code it seems ok , just checkth TIM2_CH1 pin polarity and delect the CtrlOutputEnable for TIM14.-Hannibal-
