[求助] LSM6DSO FSM手势识别的两种数组形式的疑问 ？

请教各位，刚接触LSM6DSO的FSM，本来想识别shake手势，结果在 lsm6dso_fsm.c里找不到shake手势的数组，并且是这种形式：

/* Program: glance */
const uint8_t lsm6so_prg_glance[] = {
  0xb2, 0x10, 0x24, 0x20, 0x17, 0x17, 0x66, 0x32,
  0x66, 0x3c, 0x20, 0x20, 0x02, 0x02, 0x08, 0x08,
  0x00, 0x04, 0x0c, 0x00, 0xc7, 0x66, 0x33, 0x73,
  0x77, 0x64, 0x88, 0x75, 0x99, 0x66, 0x33, 0x53,
  0x44, 0xf5, 0x22, 0x00,
};

/* Program: motion */
const uint8_t lsm6so_prg_motion[] = {
  0x51, 0x10, 0x16, 0x00, 0x00, 0x00, 0x66, 0x3c,
  0x02, 0x00, 0x00, 0x7d, 0x00, 0xc7, 0x05, 0x99,
  0x33, 0x53, 0x44, 0xf5, 0x22, 0x00,
};

而在另外一个代码里，找到一个这样的shake手势数组（unico转换出来的）：

const ucf_line_t shake[] = {
  {.address = 0x10, .data = 0x00,},
  {.address = 0x11, .data = 0x00,},
  {.address = 0x01, .data = 0x80,},
  {.address = 0x04, .data = 0x00,},
  {.address = 0x05, .data = 0x00,},
  {.address = 0x5F, .data = 0x43,},
  {.address = 0x46, .data = 0x01,},
  {.address = 0x47, .data = 0x00,},
  {.address = 0x0A, .data = 0x00,},

。。。。。

  {.address = 0x09, .data = 0x00,},
  {.address = 0x09, .data = 0x00,},
  {.address = 0x09, .data = 0x01,},
  {.address = 0x09, .data = 0x01,},
  {.address = 0x09, .data = 0x00,},
  {.address = 0x09, .data = 0x00,},
  {.address = 0x09, .data = 0xE2,},
  {.address = 0x09, .data = 0x00,},
  {.address = 0x09, .data = 0x1E,},
  {.address = 0x09, .data = 0x00,},
  {.address = 0x09, .data = 0x13,},

。。。。

}

这两种数组格式都不一样，没法将这个 shake数组导入到上面那个工程里。

并且很奇怪，第二种数组连续多个address是一样的，是什么意义呢？这种方式能不能同时支持多个手势呢？找不到工程代码使用这种数组的例子。

谢谢大佬帮忙解答！

LSM6DSO 的Shake detection例程可以在官方的github页面找到，对应的链接是：

https://github.com/STMicroelectronics/STMems_Finite_State_Machine/tree/master/application_examples

第一种原始数组通过类似lsm6dsox_ln_pg_write的函数配置

第二种数组通过类似下边方法配置

LSM6DSO的examples里只提供了RAW方式的示例，第二种示例可以参考LSM6DSOX的代码

"第二种数组连续多个address是一样的，是什么意义呢？"

可以参考下边文档，第49、50、52页有一个示例。

厉害，玩的透彻！

版主厉害，非常感谢 ，辛苦了！

另外，是否有方法可以将第二种数组转换成第一种数组呢？

因为我需要在 lsm6dso_fsm.c里处理 shake 手势，这个文件有多种手势处理，但就是缺了shake手势。

原来是地址递增了。奇怪，为什么不干脆生成绝对地址呢。

你可以参考一下lsm6dso_reg.c里的lsm6dso_ln_pg_write函数，再对照一下an5226文档和第二种数组同，应该就能弄明白它们两者的规律。

int32_t lsm6dso_ln_pg_write(stmdev_ctx_t *ctx, uint16_t address,
                            uint8_t *buf, uint8_t len)
{
  lsm6dso_page_rw_t page_rw;
  lsm6dso_page_sel_t page_sel;
  lsm6dso_page_address_t  page_address;
  uint16_t addr_pointed;
  int32_t ret;

  uint8_t i ;
  addr_pointed = address;
  ret = lsm6dso_mem_bank_set(ctx, LSM6DSO_EMBEDDED_FUNC_BANK);

  if (ret == 0)
  {
    ret = lsm6dso_read_reg(ctx, LSM6DSO_PAGE_RW, (uint8_t *) &page_rw, 1);
  }

  if (ret == 0)
  {
    page_rw.page_rw = 0x02; /* page_write enable*/
    ret = lsm6dso_write_reg(ctx, LSM6DSO_PAGE_RW, (uint8_t *) &page_rw, 1);
  }

  if (ret == 0)
  {
    ret = lsm6dso_read_reg(ctx, LSM6DSO_PAGE_SEL, (uint8_t *) &page_sel, 1);
  }

  if (ret == 0)
  {
    page_sel.page_sel = ((uint8_t)(addr_pointed >> 8) & 0x0FU);
    page_sel.not_used_01 = 1;
    ret = lsm6dso_write_reg(ctx, LSM6DSO_PAGE_SEL, (uint8_t *) &page_sel, 1);
  }

  if (ret == 0)
  {
    page_address.page_addr = (uint8_t)(addr_pointed & 0x00FFU);
    ret = lsm6dso_write_reg(ctx, LSM6DSO_PAGE_ADDRESS,
                            (uint8_t *)&page_address, 1);
  }

  if (ret == 0)
  {
    for (i = 0; ((i < len) && (ret == 0)); i++)
    {
      ret = lsm6dso_write_reg(ctx, LSM6DSO_PAGE_VALUE, &buf[i], 1);
      addr_pointed++;

      /* Check if page wrap */
      if (((addr_pointed % 0x0100U) == 0x00U) && (ret == 0))
      {
        ret = lsm6dso_read_reg(ctx, LSM6DSO_PAGE_SEL, (uint8_t *)&page_sel, 1);

        if (ret == 0)
        {
          page_sel.page_sel = ((uint8_t)(addr_pointed >> 8) & 0x0FU);
          page_sel.not_used_01 = 1;
          ret = lsm6dso_write_reg(ctx, LSM6DSO_PAGE_SEL,
                                  (uint8_t *)&page_sel, 1);
        }
      }
    }

    page_sel.page_sel = 0;
    page_sel.not_used_01 = 1;
    ret = lsm6dso_write_reg(ctx, LSM6DSO_PAGE_SEL, (uint8_t *) &page_sel, 1);
  }

  if (ret == 0)
  {
    ret = lsm6dso_read_reg(ctx, LSM6DSO_PAGE_RW, (uint8_t *) &page_rw, 1);
  }

  if (ret == 0)
  {
    page_rw.page_rw = 0x00; /* page_write disable */
    ret = lsm6dso_write_reg(ctx, LSM6DSO_PAGE_RW, (uint8_t *) &page_rw, 1);
  }

  if (ret == 0)
  {
    ret = lsm6dso_mem_bank_set(ctx, LSM6DSO_USER_BANK);
  }

  return ret;
}

好的，我好好研究一下。
