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:


It was originally inspired by LwIP coding style with some modification. Document today covers:

  • General rules like opening brackets, tabs size, etc
  • Function syntax
  • Comments and documentation
  • Structures/Enumerations
  • Macros

In case you would add some part or modify existing, feel free to propose in repository itself.
