PWM basics on the STM32 general purpose timers

The STM32 Family processors include general purpose timers that have a nice PWM function that can handle four channels of independently controlled duty cycles. In this article I will look at how to set these up for basic use suitable … Continue reading

clock pulses with variable phase on STM32

The CCRx registers can be set to directly produce regular clock pulses on one or more of the output pins. Square waves are especially simple and up to four channels can have variable phase relationships.

TIM3 ARR Gives Regular Interrupts on the STM32F4

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. This article shows you how to correctly set up … Continue reading

Basic systick configuration on the STM32

The ARM cortex processors all come with a systick timer that is part of the core and so should be present on any ARM cortex. This timer is very useful for producing the main system event clock. Here I will show … Continue reading
