Tiny printf() - C version

[timotet 44]

there is no other code just the stuff from the original post

[bluehash 1,581]

I took both programs and put them in the same project then tried to compile, am I doing this wrong?

What does "both programs" mean?

[timotet 44]

The 2 that opossum posted

 

his printf.c and his test code.

I wanted to run the the example he had posted.

 

thanks again Bluehash :thumbup:

Np.. The program should work right out of the box. Are you sure you are compiling the right program? I'm assuming this is CCS?

[timotet 44]

yep CCS ver 4.2.4

 

Am I supposed to combine the 2 programs into 1?

I have 1 project with 2 source files now.

[bluehash 1,581]

Could you zip up your project and attach it here?

[timotet 44]

sure here it is

printf.zip

[timotet 44]

Im sure it is something simple

 

I tried it in another project with the same results

 

thanks again

You also need serial.asm from here

 

It will all fit in a 2211/2231.

[timotet 44]

so do I just stick the .asm file in my existing project?

 

Thanks guys

[bluehash 1,581]

It will be in a separate file - serial.asm

I totally forgot about putc()

 

Working project attached.

printf_1.zip

[timotet 44]

Thanks Bluehash

 

What did you change? I added the serial.asm to the original project and still could not get it to compile.

[bluehash 1,581]

I made a new project. Copied the two code snippets from the first post into two different files. Also added serial.asm as a separate file.

[timotet 44]

So I tried just for fun to re-build the project from scratch.

 

I started a new project in CCS.

I copied the code from the beginning of this thread, and the serial.asm code from the post oPossum pointed out.

 

3 separate files one project. Tried to compile no dice!

 

compared the project with the one you posted that works great.

The only difference I found was when I copied and pasted the .asm file from the the other post the file ends up indented

to the right by 4 spaces in the editor window , and wont compile.

I removed the 4 spaces from each line and it works great.

 

Maybe this will help someone maybe not.

 

thanks for the great code oPossum, and thanks for helping me get it going bluehash!

This forum is awesome!!! :clap:

[timotet 44]

so I've been using this with my project and it is awesome.

 

2 questions :

 

1. Does the above post make any sense? A friend of mine that has programmed for a long time says it shouldn't matter if it is spaced over. CCS didn't seem to like it though.

 

2. oPossum could you give an example of a putc function for writing to an LCD with the printf code you posted.

I am not understanding how the printf would interact with the LCD code.

 

thanks
