Expand description

7-bit address mode type.

Note that 7-bit addresses defined by drivers should be specified in right-aligned form, e.g. in the range 0x00..=0x7F.

For example, a device that has the seven bit address of 0b011_0010, and therefore is addressed on the wire using:

  • 0b0110010_0 or 0x64 for writes
  • 0b0110010_1 or 0x65 for reads

Should be specified as 0b0011_0010 or 0x32, NOT 0x64 or 0x65. Care should be taken by both HAL and driver crate writers to use this scheme consistently.
