@ -488,3 +488,35 @@ Where <subdir> is one of the following:
examples/usbstorage - There are some hooks in the appconfig file
to enable the USB mass storage device. However, this device cannot
work until support for the SD card is also incorporated.
usbnsh
This is another NSH example. If differs from the 'nsh' configuration
above in that this configurations uses a USB serial device for console
I/O. This configuration was created to support the "DB-DP11212 PIC32
General Purpose Demo Board" which has no easily accessible serial port.
However, as of this writing, the configuration has set for the
"DB_DP11215 PIC32 Storage Demo Board" and has only be testing on that
board.
Below summarizes the key configuration differences between the 'nsh'
and the 'upnsh' configurations:
CONFIG_USBDEV=y : NuttX USB device support is enabled
CONFIG_PIC32MX_USBDEV=y : The PIC32MX USB device driver is built
CONFIG_UART1_SERIAL_CONSOLE=n : There is no serial console
CONFIG_UART2_SERIAL_CONSOLE=n :
CONFIG_CDCACM=y : The CDC/ACM serial device class is enabled
CONFIG_CDCACM_CONSOLE=y : The CDC/ACM serial device is the console
You could also use the non-standard PL2303 serial device instead of
the standard CDC/ACM serial device by changing:
CONFIG_CDCACM=y : Disable the CDC/ACM serial device class
CONFIG_CDCACM_CONSOLE=y : The CDC/ACM serial device is NOT the console
CONFIG_PL2303=y : The Prolifics PL2303 emulation is enabled
CONFIG_PL2303_CONSOLE=y : The PL2303 serial device is the console
Why would you want to use a non-standard USB serial driver? You might
to use the PL2303 driver with a Windows host because it should
automatically install the PL2303 driver (you might have to go through
some effort to get Windows to recognize the CDC/ACM device).
