这个描述的意思是 X轴数据高位只用了4bit，低位也只用了4bit的意思吗？但是为啥说是12位？

ADXL357，Y轴出现异常； 0
Answered

ADXL357测量Z、Y两个方向的振动加速度，STM32通过SPI读取后，再通过DAC输出两个通道值：0g时输出5V，+0.5g输出10V，-0.5g输出0V； ①0g加速度时，通道Z输出正常，DAC保持输出5V±0.001V。通道Y输出异常，DAC电压从 5V±0.001V 缓慢下降至4.95V后，再恢复到5V，见下图； ②上图中加了高通，纵轴换算成了加速度g，也就是缓慢负向变动了约50mg； ③出现上述异常的概率较低，不容易复现。硬件上，两个通道的处理方式一模一样； ④STM32主控...

Could you please tell me if there is a driver for the AD7768 in the Zephyr system? 0
Answered

Is there a driver for the AD7768 for the Zephyr system? Or is there a plan to develop a driver for the AD7768 on the Zephyr platform? Zephyr is a relatively new operating system for embedded systems, somewhat similar to Linux. Currently, the AD7768 project...

adxl1002 输出波动问题 0
Answered

ADXL1002 设计图：使用示波器测量 R2 电阻输出端的模拟信号，在静止不动的状态下，输出的波动超过了25mv（1g），峰峰值有80mv，这可能是什么原因造成的？

adxl382的三轴数据交换 +1
Suggested Answer

问题现象主要是发现在静止状态下，运行大概15分钟，在stream FIFO模式下，出现z轴数据移动到Y轴，（也有时候到x轴。）判断方式已经确认，从FIFO里读出的数据的channel id都是正确的，可以看到下图，0x01 为Y轴，而0x020F则是1G。这个的结果数据是从FIFO直接确认的（看来keil调试，所以可以排除后面组包导致的问题）初始化逻辑读取fifo按照先读取fifo ready和对比watermark 最后去取数据...
