Demo of CLI module.

cli_demo.c

// cli.h
// version 1.0.0

// define callback functions (can be anywhere, not just here)
void some_func(void) 		{ return; }
void some_other_func(void) 	{ return; }

// define some actions manually
// undesired, just an example!
CLI_ACTION act1 = { 0x10, &some_func };
CLI_ACTION act2 = { 0x11, &some_func };

// initialize UART module and assign to CLI
UART* uart1 = uart.new(2);

// max 8 types and 8 actions per type (#defined in cli.h)
// undesired types can be omitted
