I've connected an Arduino TFT display to display data from various pressure sensors. Im using the TFT.h and SPI.h libraries.
However, for some reason the code seems to hang during the setup() function and will not proceed to the void() loop.
Weird thing is that if i hook up the USB to the PC - the second i launch serial monitor(shift+m), the arduino program will proceed as it should and everything is working fine. My project does not use serial communication in any way.
Seems like a bug to me. Anyone experienced anything similar and/or have a workaround/fix?
