| MPU6050 Pin | Proteus Connection | Notes | | :--- | :--- | :--- | | | +5V | The library has an internal 3.3V regulator simulation | | GND | Ground | | | SCL | A5 (Arduino Uno) or Pin 6 (STM32) | Add a 4.7k pull-up resistor to VCC | | SDA | A4 (Arduino Uno) or Pin 7 (STM32) | Add a 4.7k pull-up resistor to VCC | | ADO | GND | Sets I2C address to 0x68 (Standard) | | INT | Any digital pin | Optional; used for data ready interrupt |
Without a good library, simulating an MPU6050 is impossible. With the library guide above, your virtual I2C bus will sing. You can now debug your Kalman filters and complementary filters entirely in software, saving hours of hardware debugging time.
void setup() Serial.begin(9600); Wire.begin(); delay(100);
Download the library recommended above, wire up a virtual Arduino Nano, and start plotting accelerometer data in Proteus’s Virtual Instruments panel. Happy simulating! Do you have a better library than the ones listed? Share the link in the comments below (must be a direct .LIB download).
