+.SH NAME
+ao-sky-flash \- flash GPS firmware program to a SkyTraq GPS chip
+.SH SYNOPSIS
+.B "ao-sky-flash"
+[\-T \fItty-device\fP]
+[\--tty \fItty-device\fP]
+[\-D \fIaltos-device\fP]
+[\--device \fIaltos-device\fP]
+[\--loader \fIboot-loader\fP]
+[\--firmware \fIgps-firmware\fP]
+[\--query]
+[\--quiet]
+[\--raw]
+.SH DESCRIPTION
+.I ao-sky-flash
+loads the specified GPS firmware file into the target GPS chip flash
+memory using the specified boot loader.
+.SH OPTIONS
+.TP
+\-T tty-device | --tty tty-device
+This selects which tty device the debugger uses to communicate with
+the target device.
+.TP
+\-D AltOS-device | --device AltOS-device
+Search for a connected device. This requires an argument of one of the
+following forms:
+.IP
+TeleMetrum:2
+.br
+TeleMetrum
+.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.
+.TP
+\--loader boot-loader
+This specifies the desired boot loader to use for reflashing the
+device. You should use srec_115200.bin unless you have a good reason
+not to. This should be in S record format.
+.TP
+\--firmware gps-firmware
+This specifies the new GPS firmware image to load onto the target GPS
+chip. No checking is done on this device at all; flash garbage and the
+GPS chip will probably fail to boot.
+.TP
+\--query
+Instead of loading new firmware, query the current version of firmware
+running on the target device.
+.TP
+\--quiet
+Normally, ao-spy-flash is quite chatty. This shuts it up, except for
+error messages.
+.TP
+\--raw
+The expected target for reflashing is an Altus Metrum product with the
+GPS chip connected to the CPU on that board and not directly to the
+USB serial port. This option says that the target GPS chip is directly
+connected, which changes how things are initialized a bit.
+.SH USAGE
+.I ao-sky-flash
+loads the specified bootloader into device RAM and then uses that to
+load new firmware to flash.

+ * @mainpage Pico Beacon
+ *
+ * @section overview_sec Overview
+ *
+ * The Pico Beacon is an APRS based tracking beacon that operates in the UHF 420-450MHz band. The device utilizes a
+ * Microchip PIC 18F2525 embedded controller, Motorola M12+ GPS engine, and Analog Devices AD9954 DDS. The device is capable
+ * of generating a 1200bps A-FSK and 9600 bps FSK AX.25 compliant APRS (Automatic Position Reporting System) message.
+
+
+ *
+ * @section history_sec Revision History

+ * (5) LM60 temperature sensor.
+ *
+ *
+ * @subsection v101 V1.01
+ * 5 Dec 2001, Change include; (1) Changed startup message, and
+ * (2) applied SEPARATE pragma to several methods for memory usage.
