creating component

create file with .c extension in components/

basic example

components/simple_module.c:

#include "../lib/util.h"  /* you can find some useful functions in `util.c` */

void
function_name(char *out, const char __unused *_a,
		uint32_t __unused _i, void __unused *_p)
{
	bprintf(out, "%s", "Hello, World!");
}

arg, interval and static_ptr is optional argument and if it is unused add __unused attribute

then put:

void function_name FUNC_ARGS;
#define function_name {function_name, "thread name", 0}

at the end of aslstatus.h

complex example

for complex example see brightness and then entropy component (this components are "simple" and have detailed comments)

aslstatus.h:

/* ... */

void my_module FUNC_ARGS;
#define my_module {my_module, "My Module", static_data_size}

in #define:

1. component function (should be same as define name)
2. thread name (can be same as component function name)
3. size of static data (described in brightness components sources)
