First we need to understand 2 simple things. Each binary will be placed in different sectors inside the Flash memory of our microcontroller (STM32 Family). For that reason we need to make sure about the sectors of the memory and the addressing. For example in a STM32-H743 we can alter the linker script: Run the program and notice how the LED blinking pattern has changed. Now instead of polling the timer value constantly and switching the LED on and off on certain threshold values we simply wait for the TIM_IT_Update interrupt and toggle the LED once it arrives.; The real power of hardware timers is however in the way they can send interrupts to the CPU eliminating the need to check the status ...More than 100 examples for easy understanding High quality HAL and low-layer API drivers using CodeSonar ® static analysis tool STM32L0-dedicated middleware including USB Device, and touch sensing library Free user-friendly license terms Update mechanism that can be enabled by the user to be notified of new releases Read more Get SoftwareThe size varies across STM32 families, so check your datasheet.
