Wire.beginTransmission(MPU6050_ADDR); Wire.write(WHO_AM_I_REG); Wire.endTransmission(false);
Crucial tip: The best libraries simulate the open-drain I2C bus correctly. If you forget the pull-up resistors, the simulation will hang or return 0xFF on all registers. Load this code into your Proteus Arduino source code (or VSM Studio). It reads the WHO_AM_I register—the ultimate test of a good library. mpu6050 proteus library best
