Micropython：ESP32 I2C。 SRF10传感器不返回值
我使用的是连接到ESP32-KIT的SRF10传感器。而使用它来获取数据，仅在给定的电源时才在开始时仅在开始时闪烁。我的代码为以下：
from machine import I2C, Pin
import time
#Distance units
unit_cm = 0x51
i2c = I2C(freq=100000,scl=Pin(18), sda=Pin(19))
address = 0x70 # from the scan
#Sensor range
range_mm = 255
i2c.writeto_mem(address, range_mm, bytearray(2))
#Begin reading
i2c.writeto_mem(address,unit_cm, bytearray(0))
#Reading after measurement
data = i2c.readfrom_mem(address, 0,4)
print(data)
并且印刷的数据为b'\ x05 \ x80 \ x80 \ x00 \ \ x00 \ \ x00 x00。前两个值是有道理的，但是另外两个值应该是距离的数据，总是为零。有什么问题？
I am using a SRF10 sensor connected to a esp32-kit.While using it to acquire data the light only flashes at the beginning when given power.My code is the following:
from machine import I2C, Pin
import time
#Distance units
unit_cm = 0x51
i2c = I2C(freq=100000,scl=Pin(18), sda=Pin(19))
address = 0x70 # from the scan
#Sensor range
range_mm = 255
i2c.writeto_mem(address, range_mm, bytearray(2))
#Begin reading
i2c.writeto_mem(address,unit_cm, bytearray(0))
#Reading after measurement
data = i2c.readfrom_mem(address, 0,4)
print(data)
And the data printed is b'\x05\x80\x00\x00 . The first two values make sense, but the other two, which should be the data of the distances, are always zero. What could be the problem?
