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) Pulse lengths and waveform periods can be modulated from a few microseconds to several milliseconds using the timer

November 2024 AN4013 Rev 12 1/47 1 AN4013 Application note Introduction to timers for STM32 MCUs Introduction The purpose of this document is to: • Present an overview of the timer periphera ls for the STM32 product series listed in Table 1. • Describe the various modes and specific timer features, such as clock sources.
TIM2 to TIM5 - General-purpose timers (We will focus on this in the current tutorial) TIM9 to TIM14 - General-purpose timers; TIM6 and TIM7 - Basic timers; In this post, we will see the General-Purpose timers (TIM2 to TIM5) in the STM32F7. The block diagram of the general-purpose timer is given below.
It's related to the input triggers for the advanced timers 1 and 8. I reconfigured my PWM toggle to use TIM5 so that I could use TIM5's TRGO to input into TIM1 (ITR0); TIM1 will count the rising edges of TIM5 now. In other words, TIM5 is the master of TIM1. It seems to be working quite nicely- I get a triangle wave as I count up and store the ...
Alright, I found the issue. TIM5 is used by the Arduino Giga for things such as writing to the serial port. It probably has other uses as well, but I noted that anytime Serial.println() was called for example, the counter TIM5 CR1 CEN would be enabled...
General-Purpose Timers (TIM2-TIM5): These timers are versatile and commonly used for various timing and control tasks. They have advanced features like input capture, output compare, and PWM generation modes. General-purpose timers provide a wide range of functionality and flexibility. Advanced-Control Timers (TIM1 and TIM8):
The initialization is finished by settingup the timer TIM5. The reload - value is written into the reload register TIM5_ARR, and the update event is mapped as a valid interrupt request from this timer by setting the LS bit of the register TIM5_DIER. Finally, the timer is enabled to run by setting the LS bit in control register TIM5_CR.
