For educational purposes, you can simulate the I²C communication with the MPU6050 using a generic I²C slave model:
Result: Your code will read fixed values – useful for validating I²C read functions, but not dynamic motion simulation.
Use Visual Studio + Proteus VSM SDK. Output: MPU6050.DLL. mpu6050 library for proteus
Wire.begin();
Wire.beginTransmission(0x68);
Wire.write(0x3B); // ACCEL_XOUT_H
Wire.endTransmission(false);
Wire.requestFrom(0x68, 6);
int16_t ax = (Wire.read()<<8) | Wire.read();
int16_t ay = (Wire.read()<<8) | Wire.read();
int16_t az = (Wire.read()<<8) | Wire.read();
Upload I2C scanner + basic read sketch. Verify WHO_AM_I returns 0x68.
| MPU6050 Pin | Arduino Pin | |-------------|--------------| | VCC | 5V | | GND | GND | | SCL | A5 (or SCL) | | SDA | A4 (or SDA) | | AD0 | GND (sets I2C address 0x68) | For educational purposes, you can simulate the I²C
Important: In Proteus, you must manually add pull-up resistors on SDA and SCL lines (4.7kΩ to 5V). The simulated MPU6050 does not have internal pull-ups.
The MPU6050 is one of the most popular MEMS sensors for hobbyists and engineers. It combines a 3-axis gyroscope and a 3-axis accelerometer on a single chip. But what if you want to test your code before building the hardware? That’s where Proteus ISIS comes in. Result: Your code will read fixed values –
However, Proteus does not include an MPU6050 model by default. In this tutorial, I’ll show you how to download, install, and use a custom MPU6050 library for Proteus, simulate I2C communication, and visualize sensor data.
Minimal required registers:
0x6B (PWR_MGMT_1) – Bit 6 = sleep mode
0x3B (ACCEL_XOUT_H) – 16-bit signed accel X
0x3D (ACCEL_YOUT_H)
0x3F (ACCEL_ZOUT_H)
0x43 (GYRO_XOUT_H)
0x45, 0x47 – Y, Z gyro
0x75 (WHO_AM_I) – fixed 0x68
Advanced registers (optional):
0x1A (CONFIG) – DLPF
0x1B (GYRO_CONFIG) – range
0x1C (ACCEL_CONFIG) – range
0x38 (INT_ENABLE) – interrupt control
