由于Arduino UNO正常工作在5V电压下,因此二者的连接还需要I2C Logic Level Converter。留意Converter带了I2C总线所需的上拉电阻。 功能调试 1. HTS221内置不少寄存器,每个寄存器都有一个8bit的子地址(sub-address)。在操作时,既可以单独对某个地址的寄存器进行I2C读/写,也可以在一次I2C命令中对连续的多个地址的寄存...

要用基于I2C的磁性位置传感器,首先创建一个MagneticSensorI2C类的实例: // MagneticSensorI2C(uint8_t _chip_address, float _cpr, uint8_t _angle_register_msb)// chip_address - I2C芯片地址// bit_resolution - 传感器分辨率// angle_register_msb - 角度读取寄存器msb// bits_used_msb - msb寄存器使用...
只需连接四个引脚即可开始使用传感器。 一根用于VCC，一根用于GND，两根用于I2C通信的数据线。
