Data Structures

All values are little endian

Current Magic Value Is: 0xABC6

• Note: Magic values are subject to change, but I try not to do this if I can help it.

    u32 rxFrequency; // 0
    u32 txFrequency; // 4 - 10Hz units
    u32 groups; // 8 - each 8 bits represents a group number 1-26 or 0 (slot not filled)
    u16 rxSubtone; // 12 -- 0.1 Hz units for CTCSS

    u8 pttID; // 23
    u16 magic; // 24 - If valid, channel is active, if invalid channel is inactive.

} channelInfo;

There are a total of 1002 of these structs stacked in the CHANNEL section of the flash memory. Slots 0,1 & 2 are the VFOs, slots 3 to 1001 are the 999 channels.
