Member Function Documentation

setup()

void NanoForth::setup	(	const char *	code = 0,
		Stream &	io = Serial,
		U8	ucase = 0
	)

placeholder for extra setup

n4 VM init proxy

• create Virtual Machine

Parameters

code	preload Forth code
io	iostream which can be redirected to SoftwareSerial
ucase	case sensitiveness (default: sensitive)

exec()

void NanoForth::exec

(

)

nanoForth execute one line of command input

n4 execute one line of commands from input buffer

• step through commands from input buffer
• give some cycles to user defined tasks

add_api()

void NanoForth::add_api ( U16  i, void(*)()  fp  )

static

add new (user defined) hardware task to linked-list

Parameters

i	add the user function to NanoForth task manager index of function pointer slots
fp	user function pointer to be added

yield()

void NanoForth::yield ( )

static

nanoForth yield to user tasks

n4 yield, execute one round of user hardware tasks

Note:

• 0 isr, n4: 1 blinker - 17us/cycle

• service hardware interrupts

wait()

void NanoForth::wait ( U32  ms )

static

pause NanoForth thread for ms microseconds, yield to user tasks

aka Arduino delay(), yield to hardware context while waiting

call_api()

void NanoForth::call_api ( U16  id )

static

call C API interface

Field Documentation

fp

FPTR NanoForth::fp = { NULL }

staticprivate

C API function pointer slots.
