DSM update for Millenium4 remote

[The Robman]

The DSM special protocol as currently defined doesn't work for the Millenium4 remote. This is because the Mil4 only allows macros in one device mode. In the B01 version you can select that device mode in IR but in the B00 version it's hardwired to CABLE mode.

To make the DSM protocol work, we need to trick the remote into thinking we're in the right mode and I've figured out what's needed.

The DSM code that's currenty supplied by the SP spreadsheet when you select the Mil4 is for the B01 version, here's what it currently looks like...

Code: Select all

8000:	00 00	DB	00H, 00H
8002:	01	DB	01H
8003:	E4 03 7C	LD	R7C, R03
8006:	50 C0	POP	RC0
8008:	50 C1	POP	RC1
800A:	50 C2	POP	RC2
800C:	50 C3	POP	RC3
800E:	50 C4	POP	RC4
8010:	C6 CA 06 1E	LDW	RCA, #061EH
8014:	70 CB	PUSH	RCB
8016:	70 CA	PUSH	RCA
8018:	70 C4	PUSH	RC4
801A:	70 C3	PUSH	RC3
801C:	70 C2	PUSH	RC2
801E:	30 C0	JP	@RC0

and here's what it should look like...

Code: Select all

8000:	00 00	DB	00H, 00H
8002:	01	DB	01H
8003:	E4 5F 63	LD	R63, R5F
8006:	E4 03 7C	LD	R7C, R03
8009:	50 C0	POP	RC0
800B:	50 C1	POP	RC1
800D:	50 C2	POP	RC2
800F:	50 C3	POP	RC3
8011:	50 C4	POP	RC4
8013:	C6 CA 06 1E	LDW	RCA, #061EH
8017:	70 CB	PUSH	RCB
8019:	70 CA	PUSH	RCA
801B:	70 C4	PUSH	RC4
801D:	70 C3	PUSH	RC3
801F:	70 C2	PUSH	RC2
8021:	30 C0	JP	@RC0

The difference is the LD R63, R5F (or "E4 5F 63" in hex), this is what fools the remote.

Here's what the code for the B00 version should look like...

Code: Select all

8000:	00 00	DB	00H, 00H
8002:	01	DB	01H
8003:	E4 8A 62	LD	R62, R8A
8006:	E4 03 7B	LD	R7B, R03
8009:	50 C0	POP	RC0
800B:	50 C1	POP	RC1
800D:	50 C2	POP	RC2
800F:	50 C3	POP	RC3
8011:	50 C4	POP	RC4
8013:	C6 CA 06 1E	LDW	RCA, #061EH
8017:	70 CB	PUSH	RCB
8019:	70 CA	PUSH	RCA
801B:	70 C4	PUSH	RC4
801D:	70 C3	PUSH	RC3
801F:	70 C2	PUSH	RC2
8021:	30 C0	JP	@RC0

Notice that this version uses R7B instead of R7C in the old code, and the new code I added is LD R62, R8A (or "E4 8A 62" in hex).

Both of these versions are tested.
