NOTE FOR RASPBERRY PI 3: The Raspberry pi 3 has changed things a bit and you might need to add the option enable_uart=1 at the end of /boot/config.txt (see this post by a Pi Engineer)
The Debug Buddy ultimate serial port can also be configured for 0/5 V signals. Other circuits for level shifting are shown at RPi_GPIO_Interface_Circuits#Level_Shifters. See this tutorial for an example using a ready-made level shifter module. If you wish to connect to a peripheral which has 0/5 V signals, you should ideally have a circuit to convert between the voltage levels. For using the Adafruit 954 cable on Windows, see Adafruit 954 USB serial cable.These can be simply plugged in directly to the GPIO header (see illustration).
the Adafruit 954 cable, the FTDI TTL-232R-RPI cable, or the Debug Buddy ultimate serial port). 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 3.3 V logic levels (e.g. If your Raspberry Pi has bluetooth/wireless capability, then the on-chip UART connected to the header pins is the less capable mini-UART with no break detection, no framing errors detection, no parity bit, no receive timeout interrupt and no DCD, DSR, DTR or RI signals (See RPi UART info for more details.)
See this tutorial for one example on how to build a 3.3 V to RS-232 level converter with a breadboard, a MAX3232CPE IC and five 0.1 ♟ capacitors. If you wish to connect one of these, you need a board or adapter to convert the signal levels. The ports use 0V and 3.3 V logic levels, not 0 & +5V TTL levels or the +/-12 V used by RS-232 serial ports found on some older PCs. The Broadcom chip at the heart of the Raspberry Pi has low power serial ports with limitations of voltage and protocol compatibility. You will also need to connect the Ground pins of the two devices together. To connect to another serial device, you connect the 'transmit' of one to the 'receive' of the other, and vice versa.
If the SSH is not installed, you can install it using the command below.The Raspberry Pi serial port consists of two signals (a 'transmit' signal, TxD and a 'receive' signal RxD) made available on the GPIO header. So in general, you don't need to install SSH on your Orange Pi.ġ. The SSH server is installed by default and starts with boot on Raspbian for Orange Pi and Lubuntu for Orange Pi operating system. And it is not necessary to use extra monitor linking to Orange Pi with HDMI cable in some situation, for example, Orange Pi acting as a home server. Using SSH to login Orange Pi for remote operation is very convinient, safe and of high efficiency. Plug your AV cable( color generally is yellow) into the AV port (yellow) of the Orange Pi, and the another side into you TV. Figure below is in the OS of Rasspberry Pi for Orange Pi case. You can see boot screen and desktop of Orange Pi.
Connect the Orange Pi and the monitor using the HDMI cable as showed in the figure below.ģ. We use the HDMI cable in the figure below.Ģ. Get the basic instruments: one Orange Pi with prepared OS SD card, a HDMI cable, a monitor, a micro USB power adapter, a keyboard and a mouse.
