Libraries and tutorials for STM32F4 series MCUs by Tilen Majerle
One of the greatest features on STM32F4xx for me was to get ethernet to work properly as server and client. I got it working pretty quickly and I was investigating how to make a library to be very useful and easy to use. Ethernet library is built on LwIP TCP/IP stack version 1.4.1. Library is pretty hard to “install” for first time, so I decided to provide you source files (on my Github) for Keil uVision and Coocox. Examples for Keil...
Each STM32F4 device has 23 external interrupt or event sources. They are split into 2 sections. First interrupt section is for external pins (P0 to P15) on each port, and other section is for other events, like RTC interrupt, Ethernet interrupt, USB interrupt and so on. October 1, 2014: Added external interrupts library. GPIO as Interrupt Interrupt lines I will show now how to configure GPIO pin to be an interrupt and how to handle it in your code with...
Because there is a lot of libraries I have done, I will make a table with all of my libraries at one place. When new library will be created, it will be posted here. These libraries work on both Discovery boards, if not, it will be specified. Actually, libraries should work on STM32F4xx series of microcontrollers if they have peripherals that are need for library. All STM32F4xx MCUs don’t have everything inside. 🙂 Libraries are tested on my 4 STM32F4...
In this tutorial I will talk about ADC (Analog to Digital Converter). AD converts analog voltage to digital number, that can be used in microcontrollers. STM32F4xx MCUs have up to 3 ADCs of which every has 19 channels. 16 external channels, connected to IO pins 3 internal channels Vbat Voltage on battery pin for RTC Temp sensor unusable for measure temp,only for measure difference in temperature because it can fail up to 45°C Vref Voltage reference for ADC Below is table...
