TARGET CONFIGURATION:
This is another implementation of "Hello, World" but this one uses
a USB serial driver. Configuration options can be used to simply
the test. These options include:
@ -345,13 +347,36 @@ examples/usbserial
CONFIG_EXAMPLES_USBSERIAL_ONLYBIG
Send only large, multi-packet messages. Default: Send large and small.
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:
If CONFIG_USBDEV_TRACE is enabled (or CONFIG_DEBUG and CONFIG_DEBUG_USB), then
the example code will also manage the USB trace output. The amount of trace output
can be controlled using:
CONFIG_EXAMPLES_USBSERIAL_TRACEINIT
Show initialization events
CONFIG_EXAMPLES_USBSERIAL_TRACECLASS
Show class driver events
CONFIG_EXAMPLES_USBSERIAL_TRACETRANSFERS
Show data transfer events
CONFIG_EXAMPLES_USBSERIAL_TRACECONTROLLER
Show controller events
CONFIG_EXAMPLES_USBSERIAL_TRACEINTERRUPTS
Show interrupt-related events.
Error results are always shown in the trace output
HOST-SIDE TEST PROGRAM
In additional to the target device-side example, there is also a
host-side application in this directory. This host side application
must be executed on a Linux host in order to perform the USBSERIAL
test. The host application can be compiled under Linux (or Cygwin?)
as follows:
cd examples/usbserial
make -f Makefile.host TOPDIR=../../.
RUNNING THE TEST
This will generate a small program called 'host'. Usage:
1. Build the examples/usbserial target program and start the target.
