Porting RaspberryPiVcgencmd to Python 3<\/h2>\n\n\n\n

Originally this library<\/a> was written for Python 2 but now that has been retired it was time to update it.<\/p>\n\n\n\n

The main work that needed to be done was tweaking the print statements used in the print_all_sensors.py<\/code> script. This is needed as Python 3 changed how print works by changing it so that it is now a function.<\/p>\n\n\n\n

In addition to this since Python 3 handles encoding differently I had to make tweaks to its handling. This involved taking the output of the command as a binary string and encoding it into a text string. Currently I am using UTF-8 to ensure the binary string from and use it in the program.<\/p>\n\n\n\n

These small tweaks wont change how the program is used but will allow it to be used with Python 3.<\/p>\n\n\n\n

These updates now ready it to be used with the Raspberry Pi Cluster Project<\/a> so I can log the temperature they reach.<\/p>\n","protected":false},"excerpt":{"rendered":"
