Rangefinders-i2c

What the library can do?

1. Change TOF10120 address device by usb.
2. Get data from TOF10120 device by i2c

How install

pip install rangefinders-i2c

Change address

To change the address, a usb programmer is needed. After connecting the programmer, you can find out the address using the following code

if your programmer is the only device (connect to /dev/ttyUSB0)

from rangefinders_i2c.SensorManagment import SensorManagment

managment = SensorManagment()

if there is more than one device, then you can find it using the following code

print(SensorManagment.GetUsbDeviceList())

and by selecting a device, you can specify it when initializing an instance of the class

managment = SensorManagment('/dev/ttyUSB1')

the second parameter is the port speed, by default it is 9600. To change the speed, use the second parameter when initializing the class instance

managment = SensorManagment('/dev/ttyUSB1', 4800).

After that, you should call the function setAddress

managment = SensorManagment()
managment.setAddress(48)

for all rangefinders, we use constant values: 48, 50, 52, 54, 56, 58.

Calling the set Address() function with a value other than the specified constants will result in an error: ValueError('Address must be 48, 50, 52, 54, 56, 58')

Get Data from TOF10120

In order to get the values, you should initialize an instance of the class

from rangefinders_i2c.ReadSensor import ReadSensor

sensor = ReadSensor(1)

where 1 is the smbus bus number.

You can also enable verbose mode (log error to console) using the following code

sensor = ReadSensor(1, True)

After that, you can get the value from the device by passing it the address as a parameter

address = 0x18
distance = sensor.GetDistance(address)
print("address:", address, "distance:", distance)

or

address = 24
distance = sensor.GetDistance(address)
print("address:", address, "distance:", distance)
