is there a way to write to Segger RTT logger directly (like a UART) without all the formatting etc?

user112414 over 4 years ago

I tried to deep dive through the macros, api abstractions and other layers but couldn't figure it out. The closest I got is this:

void debug_uart_print(const char * s)
{
nrf_log_frontend_std_0(0, s);
}

but it doesn't do what I want. For some reason everything has this prepended.

so in brief - in the SDK you only use one buffer, so BufferIndex should always be 0? Can you confirm this assumption please?

Hi,

You can use the NRF_LOG_RAW_INFO(...) macro for logging a formatted string without any prefix or timestamp.

It is also possible to write to RTT without using the logger library, by using the Segger RTT APIs directly. These are found in external\segger_rtt in the nRF5 SDK directory.

Best regards,
Jørgen

thanks. That macro looks useful.

I looked at the Segger API and it looks good, but you generally need a parameter called BufferIndex and I got stuck trying to trace that in the SDK. Could you give an example please?
