Attach text from Debug Console

Please enable debug output in your launch.json ("showDevDebugOutput": "raw"). It this is too large, please attach it as a file

Paste Debug Console contents here

BTW, Can I cancel the timestamp?

[haneefdm]

It is NOT messy. It is the raw output of your firmware. It appears to be writing ANSI codes intended for a console. A terminal (not all) typically takes those ANSI codes to make changes to the screen including cursor movement, font/color changes, etc. You can even write games/animation with it.

So, this is not a bug. It is not our job to turn the logfile into a terminal.

[woquchonglang]

fine, I found the code about LOGI, but what my teminal output is "INFO: xxx", the logfile output is just the "messy code", should I change the encode or code?

#define LOGI(format, ...) \
    LOG_PROTO("INFO: ", RTT_CTRL_TEXT_BRIGHT_GREEN, format, ##__VA_ARGS__)

[haneefdm]

I don't know what you or your team members prefer. You can also output the same to two channels, one intended for the console and one for the logfile and modify your #define to output both.

There are also programs/scripts to strip ANSI codes that you can look at

thank you very much ，what 's else，I only can use the port 0，when I set printf to the buffer 1 ，it doesn't work，and I have changed the rttconfig to port 1（by the stlink to debug）
