Converting simple code, AT90S1200 > 90S2313 or ATTiny2313

[RevZ]

Hi, I've got a little problem that needs solving

It's about a simple code, which I've attached in this post. It's originally for the AT90S1200, which isn't available anymore for years here now. I've read things about the AT90S2313 and ATTiny2313 being pin compatible to each other, so I was wondering if the code could be used or in a way converted so that I can use one of those chips, which I can both still easily get nowadays.. Can someone help me with this?

Thanks in advance for the help!

Kevin.

Here it is. Working and assembled.
look at the new asm file. I documented the changes. Normally you would not use the eeprom for tables (I wouldn't).Another way would be to move the table into the code segment and use the lpm instruction like so:

	ldi	ZH,high(table*2)    ;address of the table
	ldi	ZL,low(table*2)

;you can add an offset to ZL if you want to specify a specific address like so:
        adiw ZL,4                      ;go to the 4rth byte in the table
TableLp:
	lpm                               ;get byte
	mov  temp,R0                ;copy to temp
	adiw	ZL,1                      ;increment address (if needed)
;loop here or exit, whatever
