I have to convert this code to tiny 2313 I change the first .org OC1addr
rjmp TIM_COMP1
to .org 0x004
rjmp TIM1_COMPA
And now the assembler give me error on portd commands
I check the datasheet and it have the same name with 2313
Also I read the doc4298 from atmel and didnt find anything about that
Thanks for any help
The very first thing you need to do is to change .include "2313def.inc" to .include "tn2313def.inc"
...sorry I had to do something else :)
The second thing you need to do is to read AVR091: Replacing AT90S2313 by ATtiny2313.
Then start doing all the necessary changes to the code.
The very second thing is to find the include file so you can remove the errors you get.
C:\Program Files\Atmel\AVR Tools\AvrAssembler2\Appnotes
to find the include file
I have change the include before I make this post.
I have read the document 091 but about portd didnt say anything.
I except to have problem in interrupts or something like this.
I will read again of-course more carefully.
I didn't understand what to change in assember2 tn2313def.inc file
I have change the include before I make this post.
Why would you change from a named vector address to a hard-coded one?
Show the code you are >>really<< using. Preferably, a short complete test program. Tell exactly the errors you are getting. Tell which toolchain and version you are using.

I change from avr studio the assembler option to the folder avrassembler2/appnotes and build with no errors
This is the only changes I have made
from:
.org OC1addr
rjmp TIM_COMP1 ;timer1 compare handler
.org OVF1addr
rjmp TIM_OVF1 ;timer1 overflow handler
.org OVF0addr
rjmp TIM_OVF0 ;timer0 overflow handler
to:
.org 0x0004
rjmp TIM_COMP1 ;timer1 compare handler
.org 0x0005
rjmp TIM_OVF1 ;timer1 overflow handler
.org 0x0006
rjmp TIM_OVF0 ;timer0 overflow handler
ofcourse and the inlcude file
I use avr assembler 1 I dont know the difference from 1 to 2 I have to read about that
from:
.org OC1addr

You mean to name the address of oc1addr with new tiny name and not numbers?
I use avr assembler 1 I dont know the difference from 1 to 2
It should not make much difference with this project as assembler 1 also supports the Tiny 2313. HOWEVER do NOT specify the path for the include file as each assembler will find tham in their own paths. ie the include files are not necessarily the same for assembler 1 and assembler 2.
edit also look at the additional interrupt vectors in the T2313. What Lee is saying that you should not hard code the address of the ISR but rather use it's name.

Most 90s2313 programs will run just fine with a tiny2313 chip. Obviously the reverse is not true. And the fuses are very different.
Just assembling with
.include "tn2313def.inc"
creates no errors. But there are several warnings because you appear to be using the index registers for general purposes.
As far as I know the index registers have always existed on AVRs. So it seems foolish to waste them!

?? The assembler does find it for you. Smile (without the path)
Maybe I wasn't clear in my post.
If there are differences with respect to I/O register names, Interrupt vectors and what not, it's easy to find the new ones to be used looking at that file.
Of course you can get that info from datasheet but include file have it presented in a easy to find way.
Of course include files are read only.
Clear enough?
I have to convert this code to tiny 2313 I change the first.org OC1addr
rjmp TIM_COMP1
to .org 0x004
rjmp TIM1_COMPA
should be :
.org OC1Aaddr
And now the assembler give me error on portd commands
use this format:
cbi PORTD,1 or cbi DDRD,1
in your code you can define each bit. For example:
.equ TXPIN = 1 ;TX output pin .equ RXPIN = 0 ;RX input pin
then the code will look like this:
cbi PORTD,TXPIN or sbi DDRD,TXPIN
you will not get warnings if you refrain from using the upper registers r26,r27,r28,r29,r30,r31 because they are already defined in the tn2313def.inc file as XL,XH,YL,YH,ZL,ZH. This does not mean you can not use these registers, just don't try to rename them.
look in the zip file for the changes I made. I didn't look at the timer code.
hope it helps.
in the tn2313def.inc file (the one I have), there is no such thing as PD2, PD3, etc.
; ***** PORTD ************************ ; PORTD - Data Register, Port D .equ PORTD0 = 0 ; .equ PD0 = 0 ; For compatibility .equ PORTD1 = 1 ; .equ PD1 = 1 ; For compatibility .equ PORTD2 = 2 ; .equ PD2 = 2 ; For compatibility .equ PORTD3 = 3 ; .equ PD3 = 3 ; For compatibility .equ PORTD4 = 4 ; .equ PD4 = 4 ; For compatibility .equ PORTD5 = 5 ; .equ PD5 = 5 ; For compatibility .equ PORTD6 = 6 ; .equ PD6 = 6 ; For compatibility
I have to say that all you guys are very kind and give me so much help . This forum is the best forum with serious support.
Yes I finally convert the code.
Thank you all for the support continue the good job.
Definitely the best forum.
