Connecting FAST to your Computer¶
This page is about connecting the FAST system to your computer. It roughly covers connecting the bus between the nodes. For electronic details see the FAST section in the pinballmakers.com Wiki.
Connect your FAST NANO controller to your PC using USB.
Then connect the OUT port of your NANO to the IN port of your first node board. Consequently, connect the OUT port of the first node to the IN port of your second board. Connect the OUT port of the last board back to the IN port of your NANO.
number: setting for each driver/switch is its board’s position number in the
chain, then the dash, then the driver/switch number. Note that the position
number starts with zero, so the first IO board in the chain is 0, the second
is 1, etc.
Fast offers three different types of node boards:
0804 - 8 Switches, 4 Drivers¶
1616 - 16 Switches, 16 Drivers¶
3208 - 32 Switches, 08 Drivers¶
Verify Connected Boards via mpf hardware scan¶
You can run mpf hardware scan to see all connected node boards:
$ mpf hardware scan NET CPU: NET FP-CPU-002-1 01.03 RGB CPU: RGB FP-CPU-002-1 00.89 DMD CPU: DMD FP-CPU-002-1 00.88 Boards: Board 0 - Model: FP-I/O-3208-2 Firmware: 01.00 Switches: 32 Drivers: 8 Board 1 - Model: FP-I/O-0804-1 Firmware: 01.00 Switches: 8 Drivers: 4 Board 2 - Model: FP-I/O-1616-2 Firmware: 01.00 Switches: 16 Drivers: 16 Board 3 - Model: FP-I/O-1616-2 Firmware: 01.00 Switches: 16 Drivers: 16

On Linux: Add udev rules to ensure persistent device names¶
If you have more than one ttyUSB device connected to your PC (e.g. the FAST Nano and a FAST DMD) you can assign a name to your ports based on the USB port they are connected to.
First identify the port of your FAST hardware. Usually it should be
udevadm info on your port:
udevadm info /dev/ttyUSB0
This will show you the
DEVPATH. Now replace the last part
an asterisk and add an udev rules like this in
SUBSYSTEM=="tty", ACTION=="add", DEVPATH=="/devices/pci0000:00/0000:00:14.0/usb1/1-4/1-4:1.1/*", SYMLINK+="ttyNET", GROUP="adm", MODE="0660"
After a reboot you should get a
/dev/ttyNET device if you connect a FAST
device to that specific USB port. You can use that port in your config.
