HAL library 1.5- GPIO for STM32Fxxx

GPIO library is second mainly used library in your project. It is designed to be very easily used for initializing GPIO pins without making sure if clock is enabled or not because this will library do for you. It can init pin as normal or alternate with passing alternate function, it can deinit pin to set it as analog input, it can read pin, set pin and more. Library Read more about new HAL libraries Features Initialize pins with single...

All STM32 HAL libraries

In this section, I will write all libraries based on HAL drivers from ST. If you see this first time, make sure you read this post first about how structure of my libs looks like!

Disable peripherals in debug mode on STM32F4xx

Have you ever used watchdog in your application? Have you ever debug your application when watchdog was enabled and you hit stop? Watchdog did not stop in this case and when you pressed “continue” in your debugger, your program starts over because WDG has reset your system. One choice is that you remove line where you initialize IWDG, but you then must recompile and redownload and all that stuff. Wasting useful time. To avoid this problem, STM32 devices have possibility...

CPU load monitor for STM32F4xx

I’ve been searching for a simple CPU load monitor on STM32F4xx device. Today, I’ve managed to get one very, very primitive CPU load monitor for these devices. Check library here. STM32F4xx have built-in DWT (Data Watchpoint and Trace unit) which has several timers there. 2 of them are cycle counter and sleep counter. The first counts number of CPU cycles and the second counts number of cycles where CPU was sleeping. It would be very easy to get CPU load,...

Launching STM32F4xx libraries API

I have already add some links to my site. I started libraries API last week, but it wasn’t fully done for all libraries, and it is not already but it’s almost done. So, what is it going about. I use Doxygen style for commenting my libs and this powerful tool generates me a nice documentation for online purposes. Click here for documentation and API My goal is to get thing clear about functions/macros in my libs. I hope you will...
