帮我改进一这段代码import machine import time from machine import I2C from machine import Pin from machine import sleep class accel(): def __init__(self, i2c, addr=0x68): self.iic = i2c self.addr = addr self.iic.start() self.iic.writeto(self.addr, bytearray([107, 0])) self.iic.stop() def get_raw_values(self): self.iic.start() a = self.iic.readfrom_mem(self.addr, 0x3B, 14) self.iic.stop() return a def get_ints(self): b = self.get_raw_values() c = [] for i in b: c.append(i) return c def bytes_toint(self, firstbyte, secondbyte): if not firstbyte & 0x80: return firstbyte << 8 | secondbyte return - (((firstbyte ^ 255) << 8) | (secondbyte ^ 255) + 1) def get_values(self): raw_ints = self.get_raw_values() vals = {} vals["AcX"] = self.bytes_toint(raw_ints[0], raw_ints[1]) vals["AcY"] = self.bytes_toint(raw_ints[2], raw_ints[3]) vals["AcZ"] = self.bytes_toint(raw_ints[4], raw_ints[5]) vals["Tmp"] = self.bytes_toint(raw_ints[6], raw_ints[7]) / 340.00 + 36.53 vals["GyX"] = self.bytes_toint(raw_ints[8], raw_ints[9]) vals["GyY"] = self.bytes_toint(raw_ints[10], raw_ints[11]) vals["GyZ"] = self.bytes_toint(raw_ints[12], raw_ints[13]) return vals # returned in range of Int16 # -32768 to 32767 def val_test(self): # ONLY FOR TESTING! Also, fast reading sometimes crashes IIC from time import sleep while 1: print(self.get_values()) sleep(0.05) clk = Pin(("clk", 36), Pin.OUT_OD) sda = Pin(("sda", 37), Pin.OUT_OD) i2c = I2C(-1, clk, sda, freq=100000) #initializing the I2C method for ESP32 #i2c = I2C(scl=Pin(5), sda=Pin(4)) #initializing the I2C method for ESP8266 mpu= accel(i2c) while True: mpu.get_values() print(mpu.get_values()) time.sleep(2)

Here are some potential improvements to the code:

1. Add comments: The code would be easier to read and understand if comments were added to explain what each section of the code does.

2. Use descriptive variable names: Some variable names are not very descriptive and could be improved. For example, "a", "b", and "c" are not very informative variable names.

3. Use list comprehension: Instead of using a for loop to append values to a list, you can use list comprehension to make the code more concise and readable.

4. Avoid unnecessary imports: The code imports the "sleep" function twice, which is unnecessary.

Here is an updated version of the code with these improvements implemented:
