fwiwi: I am (semi-succesfully) controlling the position of a dc motor using a pid-controller (pd actually) with an H-bridge (L298N) and PWM from a timer. QEI keeps count nicely, but the 16bit range of the timer is limiting. My ideas: – Set an overflow/underflow interrupt for the QEI timer, and in the isr add/substract the 32bit global variable.
The HAL libraries will manage the main interrupt service routine (ISR) when the timer interrupt occurs (feel free to examine it in stm32l4xx_it.c). At some point in that ISR, the code will call HAL_TIM_PeriodElapsedCallback(), which we need to provide a definition for.

In old school 8-bit MCUs, we needed to reload the timer after every interrupt or after every overflow. This is not required in STM32s as it is automatically handled. Unlike most other MCUs in which timers usually count incrementally, STM32 timers can count up, down or center-aligned.
The firmware still doesn’t have startup_stm32f103x8.s file and the name of the file in startup folder is startup_stm32.s but now it has all the interrupt vectors and other definitions. The problem has vanished now and the interrupt is working like a charm. But I am still skeptic of why the startup file was missed in the first try.

A Compare Match Interrupt is issued by a timer whenever the value of the timer becomes equal to a certain predefined value. This predefined value is stored in a register known as the Output Compare Register. Compare match Interrupts are required by the CTC, Fast-PWM, and Phase correct PWM modes of a timer (see below).
STM32 input capture, simply by the edge detection on the TIMx_CHx, on the edge of the signal jump (such as rising / falling edge) time, the current timer value (TIMx_CNT) stored in the corresponding channel capture / compare register (TIMx_CCRx), complete a capture. At the same time also can trigger the interrupt /DMA configuration is captured.
Feb 03, 2016 · The simplest way to produce regular interrupts from a timer like TIM3 on the STM32 family of processors is to set up the Auto Reload Register (ARR) to generate an update event.

Say whenever interrupt increments the count for Timer0 GPIOpin should set to 1 and then interrupt 2 for Timer1 should increment timer1 count after ton(i ... \$\begingroup\$ I don't use the HAL, but the timer 1 registers are preloaded so you need to issue an update event to load new values into them. Somewhere in the HAL (maybe Base_Init?) it will be doing this, which will result in the update interrupt flag being set. That is why the timer is firing when you enable the interrupts.Use interrupts to send data by SPI; Combine SPI and DMA to send data over SPI; So let’s start with the trigger/heartbeat. Heartbeat. The heartbeat will allow us to perform tasks at regular intervals, say 1ms, and by toggling a pin we can also determine if the processor is still “alive”. For a simple heartbeat we can use the SysTick timer.

Using Timer Interrupts ¶ In order to use timer interrupts, we recommend the following sequence: Pause the timer. Configure the prescaler and overflow. Pick a timer channel to handle the interrupt and set the channel's mode to TIMER_OUTPUT_COMPARE. Set the channel compare value appropriately (this controls what counter value, from 0 to ...There are three kinds of timer in STM32: advanced timers, general purpose timers and basic timers.
