.TH AO-USBTRNG 1 "ao-usbtrng" ""
.SH NAME
ao-usbtrng \- dump random numbers from USBtrng
.SH SYNOPSIS
.B "ao-usbtrng" [OPTION...] [KBYTES]
.SH DESCRIPTION
.I ao-usbtrng
dumps random numbers from a USBtrng device. If provided KBYTES specifies the number of 1024 byte blocks to produce on standard output. Without KBYTES
.I ao-usbtrng
produces random bytes continuously until killed.
.SH OPTIONS
.TP
\-v, --verbose
increase verbosity
.TP
\-T, -tty=TTYDEVICE
This selects which tty device the debugger uses to communicate with
the target device. The special name 'BITBANG' directs ao-dbg to use
the cp2103 connection, otherwise this should be a usb serial port
connected to a suitable cc1111 debug node.
.TP
\-D, --device=ALTOSDEVICE
Search for a connected device. This requires an argument of one of the
following forms:
.IP
usbtrng:2
.br
usbtrng
.br
2
.IP
Leaving out the product name will cause the tool to select a suitable
product, leaving out the serial number will cause the tool to match
one of the available devices.
.SH USAGE
.I ao-usbtrng
opens the target device and reads the specified number of KBYTES of
random data.
