Nucleo F334R8 - basic example of a Timer TIM2 mystery

Hi guysSo I am developing a small PWM generator around the F334R8, it's overall extremely simple. All the work is done with another MCU sending data on SPI.On the F334R8, an EXT interrupt is called when the CS line is pulled down. From there the F3 l...

is there some sample code showing how to count external events with TIM3 or TIM4 (with or without interrupt)? I'm using a STM32F429Idisc with HAL library and system workbench.
