You can check which is needed with:Īnd you will see something like "crw-rw-T 1 root dialout. You will need to be a member of the dialout group to access this port (for later releases the required group is tty).
Some types of USB serial adapter may appear as /dev/ttyACM0.USB Serial Port Adapter: /dev/ttyUSB0, /dev/ttyUSB1, and so on.Built-in (standard) Serial Port: the Linux standard is /dev/ttyS0, /dev/ttyS1, and so on.
If your PC is running Linux, you will need to know the port name of its serial port: The following parameters are needed to connect to the Raspberry Pi console, and apply on both Linux and Windows. When this is done, you will need to set up a terminal emulator program on your PC as described below. You can connect the Raspberry Pi to a PC using a USB-serial cable, or (if it has an RS-232 port) a level-converter circuit - see above for details. 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.
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. You'll want to shutdown from within the emulator to make sure to not corrupt your dsk and then you can use Ctrl+Q to exit the emulator.The Raspberry Pi serial port consists of two signals (a 'transmit' signal, TxD and a 'receive' signal RxD) made available on the GPIO header.
Place your vMac.ROM (Macintosh Plus Firmware) in /home/pi/RetroPie/BIOS Place your Macintosh Plus disks in /home/pi/RetroPie/roms/macintoshĪt minimum you'll need to include a Macintosh operating system file named System Tools.dsk as when choosing any dsk the launch script launches into the OS first by default. Place your Macintosh Plus ROMs in /home/pi/RetroPie/roms/macintosh ControlsĬtrl + Escape will exit the emulator Mini vMac (Macintosh Plus)
Once you have a working disk image large enough to install other software on, you can access other install disk images from the "Unix" icon on the Mac desktop which can access the file system of the Raspberry Pi. Since the disk setup GUI is not included in RetroPie's version of Basilisk, you must install Basilisk on your PC to create a larger image and copy your disk.img file to it. If your disk.img file (from MacStartup.img) only has a few MB of free space on it while running the emulator, you must create a new larger one if you want more free space.
You will also place these files in /home/pi/RetroPie/roms/macintoshįor more details see the forum post at and the links therein for detailed instructions about how to set up Basilisk II. Mac.rom (can be renamed from PERFORMA.ROM)ĭisk.img (can be renamed from MacStartup.img) To start up your mac you need two main files: Place your Macintosh ROMs in /home/pi/RetroPie/roms/macintosh Macintosh Plus, BasiliskII also emulates 68K but supports newer hardware as well e.g. Mini vMac emulates the 68K processor macs (older software) e.g. The Apple Macintosh, later renamed the Macintosh 128K, was a personal computer released in 1984.
