Logitec F710 Game Controller for DonkeyCar

Testing to see if the Nano Recognizes the F710 USB Dongle You can use the "lsusb" UNIX shell command to list all the USB devices:

$ lsusb Bus 002 Device 002: ID 0bda:0411 Realtek Semiconductor Corp. Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter Bus 001 Device 005: ID 046d:c21f Logitech, Inc. F710 Wireless Gamepad [XInput Mode] Bus 001 Device 002: ID 0bda:5411 Realtek Semiconductor Corp. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Note that the USB device with an ID of 046d:c21f has been found in the 4th line above. The first ID before the colon is the device manufacturer (Logiteh) and the second is the id of their device (c21f). Linux looks this number up in their system and then loads the driver for this type of device.

The driver will create a device file in the /dev/input directory called js0

$ ls -l /dev/input/js0 crw-rw-r--+ 1 root input 13, 0 Aug 16 19:30 /dev/input/js0

The "c" in the first letter says that this is a character I/O device.

Now as you press any key or move any joystick you will see the events.

When I press the yellow Y we see: Event: time 1566006064.962158, type 1 (EV_KEY), code 308 (BTN_WEST), value 1 Event: time 1566006064.962158, -------------- SYN_REPORT ------------ Event: time 1566006065.129981, type 1 (EV_KEY), code 308 (BTN_WEST), value 0 Event: time 1566006065.129981, -------------- SYN_REPORT ------------

Moving the joystick generates: Event: time 1566006255.549652, -------------- SYN_REPORT ------------ Event: time 1566006255.553650, type 3 (EV_ABS), code 1 (ABS_Y), value -10923 Event: time 1566006255.553650, -------------- SYN_REPORT ------------ Event: time 1566006255.557650, type 3 (EV_ABS), code 1 (ABS_Y), value -14264 Event: time 1566006255.557650, -------------- SYN_REPORT ------------ Event: time 1566006255.561652, type 3 (EV_ABS), code 1 (ABS_Y), value -18633
