[SOLVED] Are there SystemView APIs when creating custom desktop GUI applications?
Hi, I'm Matthew. I use Nordic's PCA10040 (nRF-52 dev kit which has SEGGER's J-Link), and SES 3.
I'm new to the SystemView so my idea might sound weird.
Most of the time, people use UART/RS232 serial communication; a USB-UART converter to log or plot data.
Using Qt5, the cross-platform GUI application framework, I wanted to draw a graph or a line chart after receiving data.
However, each desktop OS required OS specific serial libraries. So I thought I can replace the UART serial communication to the SystemView.
In other words, I want to replace the UART module
and I want to create a cross-platform GUI desktop application, which is quite similar to the current SystemView, to plot data.
I use the PyQt5 (based on Python 3) and the Qt creator (based on C++).
Are there SystemView APIs or libraries available for Windows/Ubuntu 16/MacOS machines?
It would be great to read data with the J-Link and plot them on my GUI app.
-Regards, Matthew

Hi, Nino! I definitely don't need the HSS. Thanks for telling me.If you want to use something like J-Scope that relies on high speed sampling (HSS) then you will need to purchase a J-Link SDK for your company:
https://www.segger.com/products/debug-pr…/tools/j-scope/
I have installed J-Link V6.22a, by the way.
About the source, are you mentioning these "SEGGER_RTT_XXX" API functions?
I have understood that if I use the "SEGGER_RTT_printf()", a message will be transferred and a desktop program, such as the J-Link RTT Viewer, will get this message.
My point is that I want to create a program like this J-Link RTT Viewer on Windows or Mac!
Are there APIs for the desktop RTT applications in the UM08001 document, too?
-Best Regards, Matthew

Thanks, Nino.
DOC 13.3.4 RTT in other host applications
RTT can also be integrated in any other PC application like a debugger or a data visualizer in either of two ways.
• The application can establish a socket connection to the RTT Telnet Server which is
opened on localhost:19021 when a J-Link connection is active.
• The application creates its own connection to J-Link and uses the J-Link RTT API which
is part of the J-Link SDK to directly configure and use RTT.
The Nordic devzone also posted a tutorial using the telnet command.
Using both, that will solve my case! Thanks for your time!
