|

A test of the poll() and select() APIs using FIFOs and, if available,
|
||||
stdin, and a TCP/IP socket. This example also includes a nice select
|
||||
based TCP/IP server example.
|
||||
based TCP/IP server example. In order to build this test, you must the
|
||||
following selected in your NuttX configuration file:
|
||||
|
||||
CONFIG_NFILE_DESCRIPTORS - Defined to be greater than 0
|
||||
CONFIG_DISABLE_POLL - NOT defined
|
||||
|
||||
In order to use the TCP/IP select test, you have also the following
|
||||
additional things selected in your NuttX configuration file:
|
||||
|
||||
CONFIG_NET - Defined for general network support
|
||||
CONFIG_NET_TCP - Defined for TCP/IP support
|
||||
CONFIG_NSOCKET_DESCRIPTORS - Defined to be greater than 0
|
||||
CONFIG_NET_NTCP_READAHEAD_BUFFERS - Defined to be greater than zero
|
||||
|
||||
In additional to the target device-side example, there is also
|
||||
a host-side application in this directory. It can be compiled under
|
||||
Linux or Cygwin as follows:
|
||||
|
||||
cd examples/usbserial
|
||||
make -f Makefile.host TOPDIR=../../. TARGETIP=<target-ip>
|
||||
|
||||
Where <target-ip> is the IP address of your target board.
|
||||
|
||||
This will generate a small program called 'host'. Usage:
|
||||
|
||||
1. Build the examples/poll target program with TCP/IP poll support
|
||||
and start the target.
|
||||
|
||||
3. Then start the host application:
|
||||
|
||||
./host
|
||||
|
||||
The host and target will exchange are variety of small messages. Each
|
||||
message sent from the host should cause the select to return in target.
|
||||
The target example should read the small message and send it back to
|
||||
the host. The host should then receive the echo'ed message.

1. Build the examples/usbserial target program and start the target.
|

|
||||
2. Wait a bit, then do enter:
|
||||
|
||||
dmesg
|
||||
|
||||
At the end of the dmesg output, you should see the the seria
|
||||
device was successfully idenfied and assigned to a tty device,
|
||||
probably /dev/ttyUSB0.
|
||||
|
||||
3. Then start the host application:
|
||||
|
||||
./host [<tty-dev>]
|
||||
|
||||
Where:
|
||||
|
||||
<tty-dev> is the USB TTY device to use. The default is /dev/ttyUSB0.
|
||||
|
||||
The host and target will exchange are variety of very small and very large
|
||||
serial messages.
