printf for CC2530 + IAR

Hi Igor,

Thank you very much for the answer. There are two functions, and I heve a doubt with debug_msg():

1. debug_msg(). Is this function for print only values of 3 variables (max)? I don't understand the function.

2. debug_str(). only for text messages.

Thanks.

Hi Igor,

It was that I thought.

Thanks. Joaquim.

Hey,

Well, since I have pointed you to this kind of solution, I must clarify several things:

You must know that the functionality you are seeking for is a small part of the

debug_trace+mt_task modules in Z-stack

So be patient, and go step by step, try to use some inverse engineering methods.

One more suggestion, is to use Ctrl+Shift+F search options, this will perform a

search through entire project, listing search results, which makes it much easier to

trace thing back and forth. In the end, I think, you'll be able to write some printf() like

code for embedded 2530. :)

Good luck

Hi Igor,

Yes I have seen that is a small part of no simple debug_trace+mt_task modules in Z-stack.

I was looking for a function more flexible, I need print text and varible at the same time with conversion variables capatibility (like %u, %d, %3w, etc.) like printf.

I know "Ctrl+Shift+F" seach options, is basic in TIMAC and ZSTACK. I have experience :)

Thanks.

Hi Joaquin,

I have been reading this post and I would like to know if you could build a printf function . I have the same problem. What was the solution that you chose?

Hi Antonio,

Yes. It was more simple than the expected.

I just redefined the standar output of RS232.

If you uses the putchar(), this function send by the default port the data. As you know the inconvenient is you need to do previous conversions, etc.

But if you redefine the putchar function as below, you will use the printf normally (conversions types and it uses putchar to send). You don't need to do nothing more.

It works fine!

Hope this help.

Hi Joaquin,

Where I have to redefine the putchar function ?  in studio.h  file or in the application files?

Could you send me an e-mail? I'm from Spain and I would like (if you want) to ask you about  your experiences with cc2530 SoC.

Regards, Antonio Rosa.

Hi Antonio,

I defined the putchar in my applications files.

Joaquin.

You can #include <stdio.h> and use sprintf, then output the string with debug_str. That will give you the string formatting functionalities of printf.

Thanks you for your advice.

Hello,

Thank you very much for your message!

I am trying the same, I put the "printf" at the same point of SimpleBLEPeripheral example, no errors and warnings occur but I cannot see anything at the Terminal I/O!

Could you please give me the settings you follow or to send me the .zip file of the example you are executing, please ?

Thank you very much for your valuable help!
