• 相关篇《【MicroPython ESP32】ssd1306驱动0.96“I2C屏幕+mpu6050图形控制》

• ✨本案例基于Thonny平台开发。✨

• esp8266固件版本：MicroPython v1.19.1 on 2022-06-18

• 本篇需要使用的加载的mpu6050模块库（无法在Thonny里面下载到）：https://github.com/narutogo/micropython-mpu6050-

• 与之相关的库（兼容ESP32）：https://github.com/Lezgend/MPU6050-MicroPython

将库下载下来后，将模块导入进去

示例程序一

• ✨主程序通过库所提供的测试代码上添加了温度数据打印。

from machine import I2C, Pin
import q4
import time,math
import mpu
import mpu6050
i2c = I2C(scl=Pin(5), sda=Pin(4))
acc = mpu6050.accel(i2c)
acc.error_gy()
#ay=acc.get_values()
#mpu.one_filter(ay["AcX"],ay["AcY"],ay["AcZ"],ay["GyX"],ay["GyY"],ay["GyZ"])
i=0
gyx=0
gyy=0
r=[]
q=[]
while 1:
	ay=acc.get_values()
	i=i+1
	if i==124:
		#print(r)
		print(q)
		i=0
		
		#print(ay["AcX"],ay["AcY"],ay["AcZ"],ay["GyX"],ay["GyY"],ay["GyZ"])
	#r=mpu.one_filter(ay["AcX"],ay["AcY"],ay["AcZ"],ay["GyX"],ay["GyY"],ay["GyZ"])
	q=q4.IMUupdate(ay["GyX"]/65.5*0.0174533,ay["GyY"]/65.5*0.0174533,ay["GyZ"]/65.5*0.0174533,ay["AcX"]/8192,ay["AcY"]/8192,ay["AcZ"]/8192)
	Temp = ay["Tmp"]
	print("Temp:",Temp,"°C",q)
	time.sleep(1)
