====== Timer 2..5 ======

{{ timer_complete.svg?350em}}

The STM32F429ZI offers several general purpose timers. Timer 2 and 5 are 32 bit timers, while timer 3 and 4 are 16 bit timers. They may be used for measuring time (basic timer), measuring input pulse length (input capturing) or generating waveforms (output compare / PWM). The timers are fully independent and can be synchronized together. \\ \\

===== Features =====

  * 16-bit / 32-bit up, down, up/down auto-reload counter.
  * Prescaler (16 bit) to adjust counting clock, even during runtime.
  * 4 independent channels for:
    * Input capture
    * Output compare
    * PWM generation (edge- and center-aligned)
    * One-pulse output
  * Synchronization / control through external signals.
  * Interrupt / DMA generation.
\\

===== Functions =====

These functions are available:
  * The [[timer_base|basic timer]] function governs the core timer itself, eg. counting mode, reload-values, etc.
  * The [[timer_clock|clock source]] controls the clock signal, eg. internal clock source, external trigger, etc.
  * The [[timer_compare|compare]] function is used for generating PWM signals.
  * The capture function is used for capturing input signals.
