Hello,  
I have bought an infrared imaging module(mlx90640), I want to get the pixels matrix from it. It sends the data through a USB port. A lot of web links and libraries are dealing with mlx90460 module but most of them use I2C protocol. My module does not deal with this kind of protocol.  
I have tried to read the input from serial port, then I got bytes like this:  
b'\x06\t\xfb\t\xf6\n'  
b'\n'  
b'\t\xf6\t\xef\t\xfd\n'  
b'2\n'  
b'Z\n'  
b'c\n'  
b'\x97\n'  
b'\x9a\n'  
b'\xbd\n'  
can anyone help me please?
