iis3dwb唤醒中断无法实现

[THSW]

初始化寄存器的参数配置

SPI_write_reg(FIFO_CTRL4, 0x00);//fifo——mode

// SPI_write_reg(INTERRUPTS_EN, 0x00);//inter

SPI_write_reg(CTRL3_C, 0x05); //high_act no_reset

SPI_write_reg(CTRL1_XL, 0xA4); //full_scale

SPI_write_reg(CTRL3_C, 0x04); //high_act no_reset

SPI_write_reg(CTRL4_C, 0x08|0x04); //drdy_1

SPI_write_reg(CTRL5_C, 0x20); //xunhuan20

SPI_write_reg(CTRL7_C, 0x02);

SPI_write_reg(FIFO_CTRL2, 0x00); //81

SPI_write_reg(FIFO_CTRL3, 0x0a); // fifo_rate

SPI_write_reg(FIFO_CTRL4, 0x06);  //

SPI_write_reg(WAKE_UP_DUR, 0x08);//0 du du thsw  sdu sdu sdu sdu

SPI_write_reg(WAKE_UP_THS, 0x02);//(lsb*32/256)0 wu 00 0000

SPI_write_reg(SLOPE_EN, 0x20);//suocun

SPI_write_reg(INTERRUPTS_EN, 0x80);//inter

// SPI_write_reg(MD1_CFG, 0x20);//

SPI_write_reg(MD2_CFG, 0x80);//

高电平激活，根据文档例程设置，但是无法实现唤醒中断

Hi @THSW ,

Welcome to ST Community!

Have a look at our driver example on Github, I think it could help you.

我曾尝试过，fifo中断（int1 int2）可以，但是唤醒（int1 int2）仍然不行，还是说fifo（int1）和唤醒中断（int2）一起用有冲突

please help，thanks

我配置过WAKE_UP_DUR，WAKE_UP_DUR，SLOPE_EN，INTERRUPTS_EN，MD2_CFG，但是我从这些寄存器中读出来的值都是0，这是传感器的问题吗，其他的寄存器的值都是正常的
