How to achieve 32-bit timer resolution using the link system in STM32F101xx and STM32F103xx microcontrollers (AN2592)

The STSW-STM32009 embedded software package is an expansion of the Standard Peripheral Library.

This firmware provides application use cases for the general-purpose-timer peripherals embedded in the STM32 microcontrollers.

The timers in microcontrollers can be linked together internally for timer synchronization or chaining purposes.

The STSW-STM32009 describes how to use the link system to achieve the 32-bit resolution with two 16-bit timers.

For more details refer to Achieving 32-bit timer resolution with software expansion for STM32Cube and Standard Peripheral Library application note (AN2592).
