Function Documentation

◆ _stat()

void _stat	(	U8 *	ram,
		int	sz,
		Stream *	io
	)

display eForth system information

< freelist

< start of heap

< end of heap

◆ ef_save()

int ef_save ( U8 * ram )

save user variables and dictionary to EEPROM

EEPROM interface

EEPROM Save/Load

< pointer to vCP (i.e. HERE)

< uvar + colon words

store dictionary byte-by-byte

◆ ef_load()

int ef_load ( U8 * ram )

load user variables and dictionary from EEPROM

< CP addr in EEPROM (aka HERE)

prevent garbage in EEPROM
retrieve dictionary byte-by-byte

◆ ef_setup()

void ef_setup	(	const char *	code,
		Stream &	io_stream
	)

setup (called by Arduino setup)

◆ ef_run()

void ef_run ( )

VM outer interpreter proxy

◆ ef_ram()

char* ef_ram ( int i )

expose VM RAM space to Sketch

VM RAM space

Variable Documentation

◆ forth_rom

const U32 forth_rom

Forth ROM image (eforth_rom.c, generated by eforth_asm.c)

◆ forth_rom_sz

U32 forth_rom_sz

actual size of ROM

◆ forth_ram

U8 forth_ram[FORTH_RAM_SZ]

static

RAM pointer (malloc)

Forth managed memory block

Note: : dynamic allocation is usually a bad idea for MCU 1) uses 4 more bytes of RAM (freelist), 2) uses ~700 bytes of Flash (allocator), 3) does prevent IDE complaints about low memory in compile time

◆ io

Stream* io
