arduino nano+mpu6050+双mcp4725连接方式 将arduino pro mini(3.3V)、mpu6050、两个mcp4725使用几个针脚做了四层,有条件的大神可以重新画图刻板。,。 代码如下: #include "Wire.h" //引用Wire库函数 #include "I2Cdev.h" //引用I2C库函数 #include "MPU6050.h" //引用MPU6050库函数 ...
I am trying to run the i2c detect script from Arduino from http://playground.arduino.cc/Main/I2cScanner I modified the setup and started with Wire.pins(2, 0); Wire.setClock(100000); Unfortunately, the code returns error == 0 for all addresses. Am I doing something wrong? Did I not ...
