Hi,

I have read somewhere, but I can't find it now, that if you are using printf from multiple threads, you can't use buffered comms - or something to this effect.

Can someone point me to the doc that discusses this, as I want to see what exactly you have to do. When experimenting earlier, I used a critical section around my debug call to make it work, but I may have got lucky.

Do I need to post on yahoo as well, or are most people keeping an eye on both groups?

Thanks,

Andy

In some versions of the system Floating Point printf from multiple threads caused some problems.
I believe that this is resolved in the latest releases.

iprintf has always been safe (iprintf is printf without floating point, a lot smaller in the library)


It is possible that printf from multiple threads can cause output wierdness

For example task 1 is printing "The Quick brown fox jumped over the lazy dog"

and task 2 a higher priority gets woken up and prints "at the tone the time is 12:45"

What might come out the serial port is

"The Quick brown fox jat the tone the time is 12:45umped over the lazy dog"

If you need the printf's to be complete by task then you need add some protection to make sure this does not happen.
