C code style and coding rules

I’ve been trying to make my own C code style and coding rules approach, to be used in all my libs. From my first coding experience till today, I changed style many times, from first STM32F4 Library to latest projects, such as ESP_AT_Lib, onewire_uart and others.   Code style rules are published and regularly updated on my Github account, under c_code_style repository name. Please use URL below to access website: https://github.com/MaJerle/c_code_style It was originally inspired by LwIP coding style with some modification....

HAL Library 24- RTC for STM32Fxxx 23

HAL Library 24- RTC for STM32Fxxx

RTC library was ported to HAL drivers for STM32Fxxx line from my previously library RTC for STM32F4xx. If features similar things as before except some functions were changed, which are already described in HAL API. Library Read more about new HAL libraries Features Support Internal or external clock source PC14 and PC15 pins are used for external crystal oscillator STM32F4/429 Discovery does not have RTC crystal onboard. Check board’s manual on how to set it up Support wakeup interrupt Support...

HAL library 3- DELAY for STM32Fxxx 16

HAL library 3- DELAY for STM32Fxxx

Delay functions are needed in your program, no matter how optimized and fast program you wanna do. Delay functions I’ve updated my delay library to support milliseconds and microseconds delays. Milliseconds based delay is done using systick timer which makes interrupts every 1ms generated by HAL library. For microseconds based delay, DWT cycle counter is used to get maximal optimized delay. DWT unit is for F4 and F7 only, F0 series does not have DWT, because of Cortex-M0. Software timers...

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!
