STM32 Tutorial #36 - Serial Print ( UART/SWO/USB - Arduino users need to watch this!)

This video goes into detail about the many different ways a serial console can be implemented. The video also show how to make a virtual COM port using USB. Everything in this video has been explained in earlier videos in little side notes but here is the complete detailed view. Arduino users who want to move into STM32 NEED to watch this!
