I've done this once before, but it's been a long time and forgotten.Today with ch340 in Linux debugging, with a previously written serial debugging program can not send data. Just remember window under the need to install the driver, the actual Linux also need to drive to normal use. The default Linux has this driver, but some old, not used.In today's commissioning process, first plug the ch340 one end into the computerInput command: lsmod | grep usbs

In modern embedded systems, asynchronous serial communication interfaces are usually used as standard peripherals in single-chip microcomputer and embedded systems. However, as the general peripheral devices of personal computers use less and less serial ports, serial ports are gradually disappearing from personal computers, especially portable computers.
