The serial port is a low level way to send data between the Raspberry Pi and another computer system. There are two main ways in which it can be used. Connecting to a PC to allow access to the Linux console. This can help to fix problems during boot, or to log in to the Raspberry Pi if the video and network are not available. Connecting to a microcontroller or other peripheral which has a serial interface. This can be useful if you want the Raspberry Pi to control another device. Connections and signal levels. Adafruit serial cable connected to Pi. The Raspberry Pi serial port consists of two signals a transmit signal, Tx. D and a receive signal Rx. D made available on the GPIO header. To connect to another serial device, you connect the transmit of one to the receive of the other, and vice versa. You will also need to connect the Ground pins of the two devices together. The Broadcom chip at the heart of the Raspberry Pi uses 0 and 3. V logic levels, not the 1. V used by RS 2. 32 serial ports found on some older PCs. If you wish to connect one of these, you need a board or adapter to convert the signal levels. See this tutorial for one example on how to build a 3. V to RS 2. 32 level converter with a breadboard, a MAX3. CPE IC and five 0. F capacitors. If you wish to connect your Raspberry Pi to a PC with a USB port, the simplest option is to use a USB to serial cable which uses 3. V logic levels e. Adafruit 9. 54 cable, the FTDI TTL 2. R RPI cable, or the Debug Buddy ultimate serial port. These can be simply plugged in directly to the GPIO header see illustration. If you wish to connect to a peripheral which has 05 V signals, you should ideally have a circuit to convert between the voltage levels. See this tutorial for an example using a ready made level shifter module. Other circuits for level shifting are shown at RPiGPIOInterfaceCircuitsLevelShifters. The Debug Buddy ultimate serial port can also be configured for 05 V signals. NOTE FOR RASPBERRY PI 3 The Raspberry pi 3 has changed things a bit and you might need to add the option enableuart1 at the end of bootconfig. Pi Engineer. Connection to a PCYou can connect the Raspberry Pi to a PC using a USB serial cable, or if it has an RS 2. When this is done, you will need to set up a terminal emulator program on your PC as described below. Console serial parameters. The following parameters are needed to connect to the Raspberry Pi console, and apply on both Linux and Windows. Speed baud rate 1. Bits 8 Parity None Stop Bits 1 Flow Control None. Linux terminal set up. If your PC is running Linux, you will need to know the port name of its serial port. Built in standard Serial Port the Linux standard is devtty. S0, devtty. S1, and so on USB Serial Port Adapter devtty. USB0, devtty. USB1, and so on. Some types of USB serial adapter may appear as devtty. ACM0. You will need to be a member of the dialout group to access this port for later releases the required group is tty. You can check which is needed with. USB0. and you will see something like crw rw T 1 root dialout., c means character device, and root can read,write and the group dialout can read,write to the port and everyone else cannot access it. To find out if you, the current user, is in the group dialout, use the command. If you do not see dialout listed, add yourself with the command. G dialout username. You then have a choice of terminal emulation programs. Super Easy Way Using GNU Screen. Enter the command below into a terminal window. To exit GNU screen, type Control A k. Super Easy Way Using Minicom. Run Minicom with the following parameters. D PortName. You can exit Minicom with Control A x. Note If you havent configured minicom before i. RPi, you should make sure Hardware Flow Control is disabled. See Tedious Old Fashioned Way Using Minicom to configure minicom. Tedious Old Fashioned Way Using Minicom. Another method to setup minicom is described in the Tincantools Minicom Tutorial. Start Gtk. Term, select Configuration Port and enter the values above in the labeled fields. Network connection with the point to point protocol pppThe easiest way to set up a network connection between your Raspberry Pi and another computer is with an Ethernet cable. If this is not possible, as is the case for the Raspberry Pi Model A, you can set up a connection over the serial cable. This uses the Point to point Protocol PPP. A network connection running over a serial cable can be very useful for copying files onto the Raspberry Pi. Step 1 Log in to the Raspberry Pi over the serial cable and run the Point to Point Protocol Daemon. Some garbage will start appearing in the terminal. This is the cue to quit your terminal program and proceed to step two. Step 2 On your local computer, start the Point to Point protocol. On a Linux or Mac computer you can do this by typing. FTGCC2. MV 1. 15. FTGCC2. MV with the name of your serial port. In the above line, 1. IP address, the address you want your computer to have. IP address, it is the address that the Raspberry Pi will have. Test the connection. Virtual connection to the LANInstead of 1. You can chose the second address it must not yet be assigned on the LAN and be outside the DHCP range. The advantage is that the system connected to the serial line will appear as if it is directly connected to the LAN arp protocol. You must enable routing on the system directly connected to the LAN for other systems to access the system connected to the serial line. On the guest system connected via the serial cable you must set the default route pointing to the serving system, e. You should also configure etcresolv. DNS. Windows terminal set up. Lg Pc Suite Mac Os X Download. Users of Windows Vista or later will need to download a terminal program, for instance Pu. TTY, or Tera. Term. Users of Windows XP and below can choose between using Pu. TTY and the built in Hyperterminal. Pu. TTY users simply need to choose serial, select the correct COM port and set the speed, as shown in the dialog below. If you are unsure of the COM port, run Device Manager and look under Ports. USB attached serial adapters should have the name of the adapter shown the Adafruit cable comes up as Prolific USB toSerial Comm Port. Boot messages. If your connection is set up correctly, when the Raspberry Pi is booted you should see many messages as the system comes up. Uncompressing Linux. Initializing cgroup subsys cpu. Linux version 3. 2.

Unwanted serial garbage input. Note that on older software by accident the internal pullups of the Rx. D GPIO pins were not enabled, this could lead to lots of serial garbage being picked up if the GPIO pin was touched, or even if a finger was nearby. In extreme case this could lead to kernel warnings and other problems. Connection to a microcontroller or other peripheral.
