NAME

ao-cal-freq − Calibrate AltOS flight computer frequency

SYNOPSIS

ao-cal-freq [−T tty-device] [−-tty tty-device] [−D altos-device] [−-device altos-device] [−v] [−-verbose] [−n] [−-nosave] [−o cal-value-output-file] [−-output cal-value-output-file]

DESCRIPTION

ao-cal-freq drives the frequency calibration process and saves the result.

OPTIONS

−T tty-device | --tty tty-device

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.

−D AltOS-device | --device AltOS-device

Search for a connected device. This requires an argument of one of the following forms:

TeleMega:2
TeleMega
2

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.

−o cal-value-output-file | --output cal-value-output-file

Writes the resulting calibration value to the specified file.

−n | --nosave

Inhibits saving the calibration value on the device. Necessary for devices which don’t have on-board configuration storage.

−v | --verbose

Makes ao-cal-freq chatty about communication with the target device.

USAGE

ao-cal-freq opens the target device, interactively calibrates the frequency, then shows the resulting calibration values and (optionally) saves them to configuration memory and/or a file.
