TIM3 on the STM32 – an introduction
Timer 3 (TIM3) on the STM32 series of processors is one of only two timers present on all the processors in the range. Understanding this timer forms a good basis for all the other STM32 timers
Basic systick configuration on the STM32
The ARM cortex M4 and M3 processors all come with a systick timer that is part of the core. The other variants, such as the M0 may not have one. This timer is very useful for producing the main system event clock. Here I will show you how to set it up on the STM32F4xx processors to generate an interrupt every millisecond. (more…)
