STM32F4 External interrupts tutorial 125

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...

STM32F4/29 Discovery with CMSIS library in Keil uVision

From this moment, I will use in my projects Keil uVision. It’s true, that Coocox is free, but it has some bugs, which are great fixed in Keil. Keil has some limitations for free (32KB flash support, no optimization) version, but for our examples and libraries, it is just fine. For updates, look at my Github projects repository, where are all projects and libraries. There is no included my libraries in bottom project, you have to download it manually from Github. All...
