ASM start character !

Hi all

I have just upgrade from version 2.0.79 to 2.0.8.1.

I am getting errors compiling any previously used code with ASM in it.

After a bit of reading I see that in version 2.0.8.0 there was a change to the way ASM is written in any bascom file.

The trouble for me is that some of the files I use like LCD driver code (such as ili9341) that has a lot of lines of ASM.

Do I need to go through all these files and put a ! at the start of each ASM line?

Any way I can get around this?

Thanks.

Altron.

(BASCOM-AVR version : 2.0.8.1 )

You can enclose blocks of assembler code in the

I have gone through and put ! in front of all lines in the .inc file.

It has a compile error on lines that already started with a !. There is now two ! at the start of some lines.

The line reads now reads !!OUT LCD_CTRL_PORT, R16 and gives errors.

Error : 215 Line : 652 Unknown ASM mnemonic [!OUT LCD_CTRL_PORT, R16] , in File : Ili9341_inc for A4275NG ASM FIXED.inc

Should there be only one ! and never double up.

What does the original ! do in ASM?

Thanks

In ASM ! does not mean nothing. Exclamation mark in Bascom code means ASM instructions..for compier(you want to use ASM and you know what you`re doing)
Asm instructions you can read in the Atmel notes Very Happy

Some of the procesors have them >130 some of them have them less like Attiny (for example they dont have hardware multiplying(I was read this somewhere, I can be wrong))

In the another way *Basic in the libraries means basic language...

My advice is: If you want to run code that works on the previous version you should click on the every error code and fix it then CTRL + S
This will adapt library to the new compiler.

Do you use Code Explorer?

Thanks

Looking at the HELP in the older versions it recommends to have a ! at the start but it wasn't required to compile.

I guess thats why there is some ASM with ! at the start and some without.

I tried converting all double !! to single ! and it compiles and works.

I dont use code explorer. Should I be?

I lied, I do use code explorer.

Doesn't seem to work on .INC files.

Good for .BAS.

Code explorer works on INC files but only in project mode.
