Overview

STM32 devices use various types of timers, with the following features for each:



General-purpose timers are used in any application for output compare (timing and

delay generation), one-pulse mode, input capture (for external signal frequency

measurement), sensor interface (encoder, hall sensor)...



Advanced timers: these timers have the most features. In addition to general purpose

functions, they include several features related to motor control and digital power

conversion applications: three complementary signals with deadtime insertion,

emergency shut-down input.



One or two channel timers: used as general-purpose timers with a limited number of

channels.



One or two channel timers with complementary output: same as previous type, but

having a deadtime generator on one channel. This allows having complementary

signals with a time base independent from the advanced timers.



Basic timers have no input/outputs and are used either as timebase timers or for

triggering the DAC peripheral.

Table 2 summarizes the STM32 family timers.

Table 3 presents a general overview of timer features.
