Using z80asm with RC2014

Some help on using z80asm on RC2014 based system

Sample "helloworld.asm":

            org $8500
            ld	de, text	; load address for text to display.
            call	display		; call display
            ret			; we are done

display:
            ld	c, $06		; load display routine from SCM API
            rst	$30		; exec display routing
            ret			; we are done

text:
            db	"scmtapp1, Hello, World\n\r",0 ; define string to display

Assemble the source to a binary file using z80asm:

• z80asm -i helloworld.asm -o helloworld.bin Converting it to Intel Hex format (linux)
• srec_cat helloworld.bin -binary -offset 0x8000 -output helloworld.hex -intel -address-length=2

We may also use Makefile files. Example for a Makefile:

main.bin: main.asm
	z80asm main.asm -o main.bin --list=main.lst

	srec_cat main.bin -binary -offset 0x8500 -output main.hex -intel -address-length=2

clean:
	rm -f main.bin main.lst main.hex

Running it on the RC2014 with SCM Copy the resulting Hex data and paste it to the cli of SCM We got: *Ready run with: g 8000

Note: the offset parm, and g value must match the origin in the assembly code
