I am using CCS 8.3.1. I want to print any massage like "hi" ,"hello",etc. when I am read about this i understand that printf,scanf such fuction required more heap size so I change it ,but still on console there nothing will print which is in printf fuction.

Hi John,

I tried the same in CCS9.1 few weeks ago and got the same results, e.g. blank system console window. I recall with TIRTOS it worked well to report system issues. Perhaps an IOS is required for the CCS console to port the noted C library calls?

Hello Keith and John,

I am using CC2650pl board with CCS 8.3.1 and want to print some on console by using either printf() or system_printf() .

If you are using TiRTOS or No-RTOS, use the display driver library via the UART.

Were you able to try Keith's suggestion?

In addition to Keith's suggestion here are a number of other threads that discuss Sys_printf() on CC2650

Curious without RTOS if the C/C++ perspective works with console monitor. Perhaps we have to click on CCS debug perspective to run the C++ code without flashing firmware into MCU. I have never tried either one but am curious why those toolbar perspectives get loaded on CCS install.

BP101 the terminal view in CCS is just like Putty or TerraTerm or any other terminal client. The console view in CCS displays messages from the build system in CCS and the debugger. None of these things are dependent on RTOS.

If you to start a debug session in CCS without flashing the MCU you can do that. The best way to do that would be to open the target configuration view. expand the project you are wanting to debug. Right click on the ccxml file and select Launch Selected Configuration. That will launch the debugger. You can then connect. Then select to load the symbols for the program (instead of loading the program).

If you wish to discuss that further please start a new thread.

Regards,

John

There is also compiler advanced language options to enable --printf_support and scanf() level in the project. The point of mentioning TI-RTOS was that the application can port System_Printf() messages directly into the debug console view without use of C+ stdio.h, CCS monitor. That was really an unexpected application gift, very nice debug feedback.

I like your idea flash symbols via debug console too.

Perhaps yours was an ogres answer, Have a happy holidays!
