What is name of the timer/counter overflow interrupt in stm32

Question

I am using timer in input capture mode in STM32 micro with keil compiler, and I want to trigger an interrupt whenever counter register of the dedicated timer overflows.

Could anyone please tell me how i can do that? what is the name of this interrupt?

Note: I am using hal functions.

Please check out the (exact) controller type you are using on the STM homepage (you can start from here: https://www.st.com/en/microcontrollers-microprocessors/stm32-32-bit-arm-cortex-mcus.html

On the product page for your controller, you'll find a useful list of PDFs under "Resources", especially

• the Reference Manual (find the register descriptions in the TIM description of the timer you use)
• a list of Application Notes, which are relevant for all STM32 families, especially
  • AN4776 General-purpose timer cookbook for STM32 microcontrollers https://www.st.com/resource/en/application_note/dm00236305-generalpurpose-timer-cookbook-for-stm32-microcontrollers-stmicroelectronics.pdf and
  • AN4013 STM32 cross-series timer overview https://www.st.com/resource/en/application_note/dm00042534-stm32-crossseries-timer-overview-stmicroelectronics.pdf

Looking for the correct library functions, you can use STM32CubeMX to configure the timers in a GUI and have the correct driver codes generated for you.

Good luck!
