I currently have no time to reproduce, but I did look at the code. The only difference in the output, is that that welcome message is using p_printf() and the values are displayed using printf. You could try to change in the do_output() routine the 5 'printf(' to 'p_printf(WHITE,' and see what happens.
I'll give that a try. Would I need to modify the code before running make
?
Yes.. change the printf and indicated in de do-output() and then run make.

That seems to have worked, here is the change I made on line 404 in scd30.cpp:
p_printf(WHITE, (char *) "CO2: %4d PPM\tHumidity: %3.2f %%RH Temperature: %3.2f *%c ",co2, hum,temp,t);
I've submitted a pull request
Weird.. but good to know...

I will need to change more places (in case other options were requested) and post the code today. Want to add your code in the appendix of the .odt file as an example how to include in Python.
closed after making changes to the source to handle this
I'm trying to integrate your program into a python application by capturing the stdout from the console. For some reason, after displaying the starting message, individual readings will not be outputted until all readings are complete. For example, the default command
./scd30
displays 10 readings in 2 second increments. The readings will not go to stdout until all 10 have completed. This is an issue as I would like to run the program continuously./scd30 -l 0
and use the readings from there. Here is my code:
