Detailed Description

The Astrodev frame header structure.

This structure defines the header for frames used to communicate with the Astrodev radio.

This struct contains seven members: syncronization characters (sync0 and sync1), the command (destination and command), a union between the size of the payload and the response from the radio (status, sizehi, sizelo), and a header checksum (cs).

Member Data Documentation

command

Command Artemis::Devices::Astrodev::frame::frame_header::header::command

The packet command.

This represents the operation of the command, and corresponds to the low byte of the opcode. This identifies what the packet does and what sort of payload to expect.

See also

Command for listing of Astrodev commands.

cs

uint16_t Artemis::Devices::Astrodev::frame::frame_header::header::cs

Header checksum.

This is a two-byte checksum appended to the end of the frame header.

destination

uint8_t Artemis::Devices::Astrodev::frame::frame_header::header::destination

The destination of the frame.

This identifies the direction of travel for the frame and corresponds to the high byte of the opcode.

Possible options are:

• TORADIO (0x10): A command being sent from the Teensy to the radio.
• TOTEENSY (0x20): A response being sent from the radio to the Teensy.
