For the most part they are similar to the -Linux kernel coding rules by Torvalds. - -PROGRAM LOGIC -------------- -I expect a certain level of common sense from people so I won't mention the -super-basic stuff. But I would like to point out a few thing I WON'T accept -(unless there is a valid reason and an explanation of why). First, I believe -that code has to be aesthetically pleasing to watch and with a clear logic -flow so: - - - Avoid deeply nested code and recursive black magic - - - No special cases: generally the code of a function should behave the - same with any argument. Avoid horrible exceptions for magic values - - - No extreme modularization: do not write code that is extremely - encapsulated with dozens of helper functions to control every signal - that runs through the damn motherboard - -EDITOR (SPACES > TABS) ----------------------- -You can use your favourite editor but spaces are better than tabs, no -discussion. For this project every source file must have an indent of 4 -spaces. Since 80 characters is the standard terminal width, the code has to be -hard wrapped at 80, 78 or 72 characters. Also there shouldn't be any markup on -the source code for your editor, not even in the comments; just the code. - - - use spaces, 1 indent - 4 spaces - - hard wrap at 80 / 78 / 72 characters - - no markup for folds or any other editor specific feature - - -C CODE INDENT AND BRACES ------------------------- -I personally prefer the K&R coding style because it was used in 'The C -Programming Language' book from Dennis Ritchie which is the 'standard' for -learning C. But I also like Linus' kernel coding rules, so sometimes I might -use some of his rules. Anyway, you can look them up if you want to or just -look at the following example that sums most of the important stuff. - - - K&R braces and function prototypes - - snake_case for variables and function names - - pointer asterisk in front of the variable ( ex: int *p; ) - -Here's a short example that uses most of the stuff: - - #include <stdio.h> - #include <stdlib.h> - - #define MY_DEVICE_MEMORY_ADDR 0x5020 - - #define MY_DEVICE_FLAG_RDY 1 - #define MY_DEVICE_FLAG_ERR 2 - - // same for unions - struct my_device - { - volatile uint8_t buffer;
