LeMaker Guitar:Debug COM
Serial port is a interface for serial communication. It transmits data in the order bit by bit. Usually ,it is connected by three lines (TX, RX and GND). Desktop PC usually has a 9-pin D-type COM port, also called RS232, but it can’t be connected directly to the LeMaker Guitar. You have to convert its levels signals to the TTL levels signals. If your computer does not have serial ports, then USB-to-Serial (TTL) module or USB-to-Serial(TTL) cable is needed to connect to LeMaker Guitar.
Note: If you use the USB-to-TTL cable in the startup phase, make sure that the USB is connected to the PC. Or the Guitar will stoped at the uboot stage. (LeMaker Guitar get some messy code from USB-to-TTL's chip at the startup stage and going into uboot.)
