Control raspberry pie through serial port

Demand

Without the Internet, keyboards and monitors, controlling raspberry pie becomes a problem. Today, I came across an article saying that raspberry pie can be controlled directly through the serial port. Try decisively, the effect is good, share decisively!

# preparation

Raspberry pie development board (this is raspberry pie Model B +) (official system has been brushed, in fact, as long as it supports serial port debugging)

USB to Serial Port tool (PL2303)

DuPont Line (4)

# Connect

PL2303 raspberry pie

VCC + 5V

RX RXD (GPIO14)

TX TXD (GPIO15)

GND Ground

Raspberry pie pin distribution map:

Physical connection diagram:

Directly use the laptop power supply, of course, you can also add a power supply.

# install software

The environment is ubuntu 14.04.

Install ckermit

$sudo apt-get install ckermit

Edit the configuration file: $vi ~ / .kermrc and write the following:

Set line / dev/ttyUSB0set speed 115200set carrier-watch offset handshake noneset flow-control nonerobustset file type binset file name litset rec pack 1000set send pack 1000set windows 5windows

Under windows, you can use HyperTerminal or putty, select a com port, and then set the baud rate 115200 to connect.

# start connecting, insert PL2303 into computer USB, and start raspberry pie

Sudo kermit

Open kermit, type c, hit enter, and you should see some output when the raspberry pie starts

After startup, enter the user name and password to control the raspberry pie

# how to disconnect

Enter the shortcut key: CTRL\, and then press c to exit to the kermit interface. Type c again to connect to the raspberry pie and exit to exit kermit

# feel that it is much more convenient to connect through the serial port. After all, most of the time we don't need or don't have a monitor. It's enough to just control the raspberry pie.
