Code formatting conventions

Wiki

To insert code, use the <code cpp> tag.

Casing

Macros : SCREAMING_SNAKE_CASE
Structures / Types / Constants / Enum members : PascalCase
Variables / Fields : camelCase

Indentation

Thou shalt in all your code use the Allman's style brace indentation (i.e. braces should always be on their own line, no matter if struct, if, while, etc.)

struct MyStruct
{
    int32_t uselessField;
    uint16_t anotherUselessField;
}

Type names

When defining fields of number type, you must use the types defined in stdint.h :

Specifier	Signing	Bits	Bytes	Minimum Value	Maximum Value
`int8_t`	Signed	8	1	−2⁷ which equals −128	2⁷ − 1 which is equal to 127
`uint8_t`	Unsigned	8	1	0	2⁸ − 1 which equals 255
`int16_t`	Signed	16	2	−2¹⁵ which equals −32,768	2¹⁵ − 1 which equals 32,767
`uint16_t`	Unsigned	16	2	0	2¹⁶ − 1 which equals 65,535
`int32_t`	Signed	32	4	−2³¹ which equals −2,147,483,648	2³¹ − 1 which equals 2,147,483,647
`uint32_t`	Unsigned	32	4	0	2³² − 1 which equals 4,294,967,295
`int64_t`	Signed	64	8	−2⁶³ which equals −9,223,372,036,854,775,808	2⁶³ − 1 which equals 9,223,372,036,854,775,807
`uint64_t`	Unsigned	64	8	0	2⁶⁴ − 1 which equals 18,446,744,073,709,551,615

Also, when defining pointer fields, the * must be on the right-side:

uint32_t *fieldName;

instead of

uint32_t* fieldName;
