Library 12- OneWire library for STM32F4

1-Wire is a device communications bus system designed by Dallas Semiconductor Corp. that provides low-speed data, signaling, and power over a single signal. It’s used in some temperature sensors, like DS18B20 temp sensor and many others products from Dallas. OneWire key features Single Contact Sufficient for Control and Operation Unique ID Factory-Lasered in Each Device Power Derived from Signal Bus (“Parasitically Powered”) Multidrop Capable: Supports Multiple Devices on Single Line Exceptional ESD Performance source: maximintegrated.com 17th May, 2014: There was some new functions added!...

STM32F4 PWM tutorial with TIMERs

In this tutorial, I will show you, how to implement PWM outputs on STM32F4xx devices. This is for a lot of people pretty hard work, but believe me, it’s quite quick and easy. I will go step by step on how to make a PWM output on specific timer. Update: I made a library for PWM, available here. STM32F4 timers They have up to 14 timers inside. Table below shows their description. You have to know, that let’s say F401 doesn’t...
