STDIO DISPLAY ON BL4S200

Hello,

I have a program including debug stdio screen display. I would like to have this feature, when stdio is connected, program will send some parameters to stdio, otherwise, no information is sent, do I have possibility to detect stdio (like DC10.72) connected by program?

thanks Start a New Thread

If nothing's connected, it shouldn't matter that you're still sending output to STDIO.

If you're using the Rabbit's built-in methods to redirect STDIO to a serial port, then I don't think there will be an easy way to conditionally send output. You'd probably have to create a wrapper for printf() that checks an I/O pin (CTS on the serial port?) before handing the parameters off to vprintf() using a va_list parameter.

Hello, Tom:

thank you for your response. I find a alternative solution. I ask user to type 'd' from debug std when the program starts, if program doesn't get answer for certain time (for example ,5 second), I will stop debug display task, so I can save some resource.
