Color in RTT Viewer

[Paul]

I want to highlight some items in RTT Viewer So I tried the color control, but didn't work This is my code.

SEGGER_RTT_printf(0, "%s[Mutex error:%u]\n%s", RTT_CTRL_BG_BRIGHT_RED, status, RTT_CTRL_RESET);

But I got the control string directly printed in the RTT viewer. Did I miss anything? Thanks

Have you tried the examples provided on the Segger page: www.segger.com/jlink-rtt-viewer.html ?

[Paul]

Yes, I did, but I only get the control strings. What is the trick?

Looks like the \e in SEGGER_RTT.h is not correctly handled as ESC. You can fix this by replacing \e with the correpsonding ASCII oct 033.

In SDK_INSTALL_FOLDER/external/segger_rtt/SEGGER_RTT.h

Replace #define RTT_CTRL_RESET "\e[0m" with #define RTT_CTRL_RESET "\033[0m"

and #define RTT_CTRL_BG_BRIGHT_RED "\e[4;41m" with #define RTT_CTRL_BG_BRIGHT_RED "\033[4;41m"
