- When adding new entries, please add all 5 related changes, since
- it helps keep everything consistent:
- 1) User structure entry
- 2) User data entry
- 3) Structure short-cut entry
- 4) Data short-cut entry
- 5) Command identifier entry
- For Example ("GETSPEED"):
- 1) struct RCgetspeed_tag { U32 LinkSpeedCode; } RCgetspeed;
- 2) struct RCgetspeed_tag *getspeed;
- 3) #define RCUS_GETSPEED data.RCgetspeed;
- 4) #define RCUD_GETSPEED _RC_user_data.getspeed
- 5) #define RCUC_GETSPEED 0x02
-
- Notes for the "GETSPEED" entry, above:
- 1) RCgetspeed - RC{name}
- RCgetspeed_tag - RC{name}_tag
- LinkSpeedCode - create any structure format desired (not too large,
- since memory will be unioned with all other entries)
- 2) RCgetspeed_tag - RC{name}_tag chosen in #1
- getspeed - arbitrary name (ptr to structure in #1)
- 3) RCUS_GETSPEED - RCUS_{NAME} ("NAME" & "name" do not have to the same)
- data.RCgetspeed - data.RC{name} ("RC{name}" from #1)
- 4) RCUD_GETSPEED - _RC_user_data.getspeed ("getspeed" from #2)
- 5) RCUC_GETSPEED - unique hex identifier entry.
