SEGGER EMBEDDED STUDIO REAL TIME TERMINAL HOW TO
It looks the connection works, however, how to see the printouts? I am trying to print out either via the printf() or the Segger RTT functions. OK, this problem has been partially solved with adding the "path" to the project, indeed, this time I can compile and run the project, but still no output either in Debug terminal or via the J-Link RTT viewer, apropos I hope that I am "connected properly", for example, while the project is ran in the emStudio, the JLink Viewer is separately opened, I guess this is the right way to do it? Please have a look at the attached picture. Notes (1) If there is not enough space in the 'Up'-buffer, remaining characters of pBuffer are dropped. With RTT it is possible to output information from the target microcontroller as well as sending input to the application at a very high speed without affecting the target's real time behavior. It combines the advantages of SWO and semihosting at very high performance. change the value of a configuration parameter in real-time without having to recompile and reflash the code). RTT enables bidirectional communication, so it can also be used to input data to the embedded code (e.g. Return values Number of bytes which have been stored in the 'Up'-buffer. SEGGER's Real Time Transfer (RTT) is a technology for interactive user I/O in embedded applications. The output of these functions can be viewed on the PC terminal or logged to a text file using J-Link RTT Viewer application. NumBytes Number of bytes to be stored in the SEGGER RTT control block. Interestingly, the simple and other "hello world" is ran I can see the print out in the 'Debug terminal'. Does not need to point to a 0 terminated string. This does not work with the project "Hello World" that I have opened from the dev board supplier, however, the application works OK, indeed, I cannot add the printf() to the code, e.g. It also enables low-level communication with the target via JTAG.
High-Speed Sampling, the SEGGER Real-Time Terminal, SWO and Simple Trace can be used directly in the application.
They can also set breakpoints and watchpoints (including setting Unlimited Flash Breakpoints). I just want to use the 'printf()' function and print out in the EmbeddedStudio and its 'Output' in 'Debug terminal'. Users also get complete control of the target (run, halt, reset, step).
