Isis Proteus Model — Library Gy 521 Mpu6050l Upd Exclusive

Add a new, exclusive simulation model for the GY-521 breakout board based on the MPU6050L (low-power 6-axis MEMS IMU) to the ISIS Proteus library. This model supports I²C communication, accelerometer & gyroscope data output, and includes visual representation for schematic design and simulation.

The UPD Exclusive model shines with interrupt simulation.

The exclusive UPD model is distributed through:

Fix: Check that pull-up resistors (4.7k) are present on SDA and SCL in your schematic. The UPD model often includes them internally, but some versions require external.

This code reads accelerometer & gyro data from a real MPU6050 (works also in Proteus if model supports register reads).

#include <MPU6050.h>  // Install via Library Manager (by Electronic Cats)
MPU6050 mpu;
void setup() 
Serial.begin(115200);

Serial.println("MPU6050 not found");

mpu.setGyroRange(MPU6050_RANGE_250_DEG);

For Proteus simulation – If your model does not support the MPU6050 library, write direct I²C read:

#include <Wire.h>
#define MPU_ADDR 0x68
void setup() 
Serial.begin(115200);
Wire.begin();
Wire.beginTransmission(MPU_ADDR);
Wire.write(0x6B);   // PWR_MGMT_1 register
Wire.write(0x00);   // wake up
Wire.endTransmission();
 The UPD Exclusive model shines with interrupt simulation
void loop() 
Wire.beginTransmission(MPU_ADDR);
Wire.write(0x3B);   // ACCEL_XOUT_H
Wire.endTransmission(false);
Wire.requestFrom(MPU_ADDR, 14, true);
// Read 6 accelerometer + 6 gyro bytes
int16_t ax = Wire.read() << 8
