HAL library 01- RCC for STM32Fxxx

This is first description for libraries in HAL section for STM32F4 and F7 lines using HAL drivers provided from ST for each section. RCC (Reset and Clock Control) library is needed to set up clocks for running STM devices at high speed. It sets up PLL parameters provided from user and enables internal or external high speed clock. Library Read more about new HAL libraries Features Works on STM32F0xx, STM32F4xx and STM32F7xx series Enables HSE or HSI oscillator Sets PLL...

Library 20- Independent watchdog timer on STM32F4

Sometimes you need watchdog timer to look at your system if it gets stuck. I made a little library to work with it. Watchdog in STM32F4xx device has it’s own clock which is independent from main system clock. You have to constantly reset it’s counter value or it will elapse and reset MCU. Watchdog Library Features Detect if system was reset by watchdog Supports different timeouts Reset watchdog
