Overview

The SCL3300-D01 is a high performance inclinometer sensor component. It is a three-axis inclinometer sensor with

angle output based on Murata's proven capacitive 3D-MEMS technology. Signal processing is done in a mixed

signal ASIC with flexible SPI digital interface. Sensor element and ASIC are packaged into 12 pin pre-molded

plastic housing that guarantees reliable operation over product's lifetime.

The SCL3300-D01 is designed, manufactured and tested for high stability, reliability and quality requirements. The

component has extremely stable output over wide range of temperature and vibration. The component has several

advanced self-diagnostics features, is suitable for SMD mounting and is compatible with RoHS and ELV directives.

值了，驱动代码很好用，入口函数讲的很明白，下面那些说不能用的，先提高自己能力吧，就一个硬件SPI的初始化，吃不了这碗饭建议放弃！感谢楼主分享。
