New tutorials from user Slemi

User Slemi posted 2 tutorials on how to install SW4STM32 and how to install STM32CubeMX. Installing STM32CubeMX Installing System Workbench for STM32 SW4STM32 They are mainly written for total beginners and are step-by-step guide how to install. If you have troubles with installation, check above links.

HAL library 04- EXTI for STM32Fxxx 6

HAL library 04- EXTI for STM32Fxxx

EXTI library is used to set GPIO pin as external interrupt. It is designed to easily enable/disable interrupt and handle irq requests. If you don’t know how EXTI works on STM32F4 or STM32F7 lines, you should take a look here. Library Read more about new HAL libraries Features Allows up to 16 external interrupts at a time Allows to setup rising or falling edge for pin Allows to disable interrupt Single function for interrupt handling Works for STM32F0, STM32F4 and...

Library 38- External interrupts for STM32F4 31

Library 38- External interrupts for STM32F4

A new library is here. 38th are external interrupts. This library allows you to very easly use external interrupts for your needs with just one function and function handler. I have written everything you need to start. For more informations on how external interrupts works on STM32F4 with pins and lines and so on, you should look at my external interrupts tutorial. I tried explain there everything as best as I can. I think it’s quite understandable. I will just...

STM32F4 External interrupts tutorial 122

STM32F4 External interrupts tutorial

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...

All STM32F4 libraries 121

All STM32F4 libraries

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...
