Python • How do I use mpu6050 data in raspberry pi to move mouse cursor?

this is my code
I'm trying to make an air mouse using mpu6050 data in raspberry pi, but in esp32 and Arduino, the mouse function was implemented well except for absolute coordinates, but when I tried to do it in raspberry pi, I asked them to use the pyput library or pygame library. As a result of correcting and executing all errors that occur while writing the code, the data in mpu6050 seems to change every time the mouse moves, so it reads well, but the mouse cursor does not move according to the changing data. I want the mouse cursor on the screen to actually move the same if mpu6050 actually moves. Because I'm going to make an air mouse and use it in practice. I want you to teach me what the problem is. I'm using raspberry pi4 and mpu6050.

pygame.init()
screen = pygame.display.set_mode((1920, 1080))
pygame.mouse.set_visible(False)

bus = smbus2.SMBus(1)
bus.write_byte_data(MPU_ADDR, PWR_MGMT_1, 0)

def read_word_2c(addr):

value = (high << 8) + low
if value >= 0x8000:
value -= 0x10000
return value

def get_sensor_data():
accel_x = read_word_2c(ACCEL_XOUT_H)

return accel_x, accel_y, accel_z, gyro_x, gyro_y, gyro_z

def main():
running = True
x, y = pygame.mouse.get_pos() # 현재 마우스 위치 가져오기

while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False

# 센서 데이터 읽기
accel_x, accel_y, accel_z, gyro_x, gyro_y, gyro_z = get_sensor_data()

# 데이터 출력
print(f"Accel X: {accel_x}, Accel Y: {accel_y}, Accel Z: {accel_z}")
print(f"Gyro X: {gyro_x}, Gyro Y: {gyro_y}, Gyro Z: {gyro_z}")

# 민감도에 따른 조정
gyro_y /= sensitivity
gyro_z /= sensitivity

# 마우스 이동 거리 계산
mouse_x = int(gyro_z)
mouse_y = int(-gyro_y)

# 현재 마우스 위치 업데이트
x += mouse_x
y += mouse_y

# 화면 경계를 벗어나지 않도록 조정
x = max(0, min(x, screen.get_width() - 1))
y = max(0, min(y, screen.get_height() - 1))

# 마우스 위치 설정
pygame.mouse.set_pos((x, y))

# 일정 시간 대기
time.sleep(0.02)

pygame.quit()
if name == "main":
main()

And then last
Try to pyautogui

Add img
Hmm.m... error to upload. . Anyway no error but can't move cursor what should I do .
