PL2303 - emulates PL2303
Seven_CDCs - 7 CDCs in one device
usart1 - read data from USART1 and send it back (blocking sending)
usart1fullDMA - USART1 Rx and Tx DMA access (Rx terminated by character match of '\n' or buffer overflow).
usarts - work with all three USARTs with Tx DMA, send to USART1 data read from other, you can send "2\n" or "3\n" to USART1 for tests of USART2/USART3
USB_template - old USB template
