I am running a program on the OV5640 sensor.
When i like to debug or test the program, i would like to see results with the print() instruktion. I can program that or not…
But if the OV5640 sensor is running without the USB cable ( “stand alone” ) the print() instruktions are not necessary. (only if i use a screen shield, right?)
What does happen with the print task, when no USB is connected?
How can i tell, that the OV5640 sensor “sees” a usb cable is connected or not, so i can use that in my program?
does is make a difference in CPU process time; printing or not printing?
