Racing controller manual

Ver1.00

■ Overview of racing controller

A 1-axis analog peripheral dedicated to racing games.
The main body is equipped with X, Y, Z, start, A, B, C buttons and a butterfly shift on a single-axis handle. For digital bits (Right, Left, Down, Up), (Left, Right) is output on the left and right of the steering wheel, (Down) is output for the butterfly shift on the right side, and (Up) is output on the left side.

L and R buttons are not equipped.

■ Racing controller data format

● Saturn Peripheral ID

Saturn Peripheral Type: 1H (Analog Device)

Data size: 3H (3 bytes)

Racing controller data format

	bit7	bit6	bit5	bit4	bit3	bit2	bit1	bit0
Peripheral ID	0	0	0	1	0	0	1	1
1st data	Right	Left	Down	Up	Start	ATRG	CTRG	BTRG
2nd data	1	XTRG	YTRG	ZTRG	1	1	1	1
3rd data	AX7	AX6	AX5	AX4	AX3	AX2	AX1	AX0

Start, ATRG, CTRG, BTRG, XTRG, YTRG, ZTRG will be 0 (ON) when the button is pressed.

The Down and Up of the butterfly shift will be 0 (ON) when you put it in front.

For AX7 to AX0, the absolute value of the A / D converter output without a sign is output.

For AX7 to AX0, 0 is on the left and 255 is on the right. The center is 127. (See Fig. 1)

Note: Since the lower 3 bits (= 111B) of the 2nd data are reserved for future expansion, programming that expects "1" for this data is prohibited.

● About digital bits

Digital Bit Threshold (Note: The actual trajectory is an arc)

← Left rotation Center right rotation →
← → ｜ ← →
ON OFF | OFF ON
−− ＋ －－－ ＋ －－－ ＋ －－－－ ＋ －－－－ ＋ －－－ ＋ －－－ ＋ －－
00h 67h 6Fh 7Fh 8Fh 97h FFh
-80 -15 -100 ° +10 +15 +80

Right is "0" (ON) when AX is 97H (+ 15 °) or more, and "1" (OFF) when AX is 8FH (+ 10 °) or less.

Left is "0" (ON) when AX is 67H (-15 °) or less, and "1" (OFF) when AX is 6FH (-10 °) or less.

Down is "0" (ON) when the right side of the butterfly shift is pulled toward you, and "1" (OFF) when it is released.

Up is "0" (ON) when the left side of the butterfly shift is pulled toward you, and "1" (OFF) when it is released.
