根据你的要求，我修改了代码，使其只控制振镜X，并根据读取到的数组值决定振镜X偏转方向（1为向左偏转，0为向右偏转）。以下是修改后的代码：

#define MaxDots 1024
u32 MapData[MaxDots];
int LDcnt = 0, LDdir = 1;
int LDlen = MaxDots;

s32 xDir = 1, yDir = 1;

void OscDispAutoMagic(unsigned char Data, u32 SizeX, u32 SizeY, u32 OffsetX, u32 OffsetY) {
    static u32 pos = 0;
    static s32 x = 0, y = 0, z = 0;
    static u32 id = 0;

    #ifdef PWMlightMode
    if (id == 0) {
        PAout(7) = 0;
    }
    #endif

    if (DotPath[pos] == 1) {  // 如果读取到1，振镜X向左偏转
        x -= 24;
    } else if (DotPath[pos] == 0) {  // 如果读取到0，振镜X向右偏转
        x += 24;
    }

    DAC->DHR12RD = MapData[LDcnt];
    LDcnt++;
    if (LDcnt >= LDlen) {
        LDcnt = 0;
        PAout(6) = 0;
    } else {
        PAout(6) = 1;
    }

    #ifdef PWMlightMode
    } else {
        PAout(7) = 1;
    }
    id = (id + 1) % 2;
    #endif
}

    }

    while (1) {

                } else if (DotPath[2 * i] == 0) {  // 如果读取到0，振镜X向右偏转
                    MapData[i] = XYc_Output(DotPath[2 * i + 1] * 24, x);

            }

            else if (Msg_PathFin >= 3) LDlen = Msg_PathFin;
            else LDlen = Msg_PathFin + 2;
            Msg_PathFin = 0;
        }
    }
}

请注意，我只根据你提供的要求修改了代码中涉及振镜X控制的部分，其他部分保持不变。请在实际使用时进行适当的调整和测试。
