Which is the external clock mode in STM32?
External clock mode1: external input pin (TIx) External clock mode2: external trigger input (ETR) Internal trigger inputs (ITRx): using one timer as prescaler for another timer, for example, you can configure Timer 1 to act as a prescaler for Timer 2
What are the functions of a tim2-tim5 timer?
Lecture 5 Prof. Yasser Mostafa Kadah TIM2-TIM5 Introduction The general-purpose timers consist of a 16-bit auto-reload counter driven by a programmable prescaler. Measuring the pulse lengths of input signals (input capture) Generating output waveforms (output compare, PWM)
When to use compare interrupt flag in STM32?
The Output compare interrupt flag of channels configured in output is set when: the counter counts down (Center aligned mode 1, CMS = “01”), the counter counts up (Center aligned mode 2, CMS = “10”) the counter counts up and down (Center aligned mode 3, CMS = “11”) In this mode, the direction bit (DIR from TIMx_CR1 register) cannot be written
How to remap PWM signal to pin Pb3?
This code generates a PWM signal for HSYNC using TIM2 Channel 2, which is output on port PA1. This all works correctly. Now I would like to remap TIM2 so that the PWM signal is remapped to pin PB3.

When is center aligned mode active in STM32?
Center-aligned mode is active when CMS bits in TIMx_CR1 register are not equal to ’00’.
