The MCUXpresso SDK for LPC54S018J4M includes USB stacks for both host and
device, with several supporting application examples.
8.2.1 USB full-speed port (USB0)
The LPC54S018J4M Full Speed (FS) USB port is connected to micro AB USB connector
J3. This section describes functionality support by this board and associated jumper
settings for this board.
8.2.1.1 Device mode
The FS port supports USB device mode operation; no jumper settings are needed to
configure this mode. When using the port in device mode, a standard micro USB cable
can be used.
8.2.1.2 Host mode
The FS port supports USB device mode operation but, due to sharing of some signals
and power supply circuitry, requires the following settings:
•
Connect ex5V power via USB connector J1. This is required for the FS USB
port to be able to power the devices connected to it.
•
Install JP10
•
For each of JP9, JP11, JP12, JP13 install a jumper in position 2-3.
•
Use of a micro AB adaptor to connect an external USB device may be required, as
most USB device have either a type A or micro B connector.
Note: The Ethernet and HS USB Host functions are disabled when the board is
configured for FS USB Host operation. Also, note that Expansion connector port PIO4-7
is no longer available when using this mode.
8.2.2 USB High Speed port (USB1)
The LPC54S018J4M High Speed (HS) USB port is connected to micro AB USB
connector J2. This section describes functionality support by this board and associated
jumper settings for this board.
8.2.2.1 Host mode
The HS port supports USB device mode operation but, due to sharing of some signals
and power supply circuitry with the FS port, requires the following settings:
•
Connect ex5V power via USB connector J1. This is required for the HS USB
port to be able to power the devices connected to it.
•
Ensure JP10 is not installed (default).
•
Install a jumper at JP9 in position 1-2 (default).
•
Use of a micro AB adaptor to connect an external USB device may be required, as
most USB device have either a type A or micro B connector.
(Note: Although not required for the HS USB port operation, it is recommended to check
JP11, JP12 and JP13 have a jumper in position 1-2 to enable Ethernet operation and
availability of the I/O at the Expansion connector D8.)
