Silencing Macros

The package contains the macros VCU_silent and VCU_silentErrors which can be used to silence the stdout and stderr outputs of their contents, respectively. For example:

VCU_silent(
	some_noisy_libaray_call();
)

will only print the output of stderr to the screen. You can also combine these to completely silence terminal output such as:

VCU_silent(
	VCU_silentErrors(
		some_very_noisy_libaray_call();
	)
)

Timing functions

The package contains the functions VCU_time_realtime_ns and VCU_time_monotonic_ns to get the real and monotonic time of the system, respectively. These can be used to time the execution of code or provide timestamps of sensor readings.

Terminal Font Manipulation

These definitions allow you to manipulate the terminal output in various ways. You can change the face/color of print statements like such: printf("This sentence has both " FONT_BOLD "bold" RESET_FONT " and " COLOR_RED "red" RESET_COLOR "text in it!"); resulting in: “This sentence has both bold and red text in it!”
