A python library to get linux/raspberry pi info

Project description

Linux Information

work in progress

Answers:

  • is this a raspberry pi?
    • functions return None on error
  • is this a raspbian or ubuntu distro?
  • is this distro based on debian?
  • reads /proc/cpuinfo for revision code
  • reads /etc/os-release for linux OS info

Info

Reads the revision code which encodes a bunch of information as uuuuuuuuFMMMCCCCPPPPTTTTTTTTRRRR. This library decodes that number.

RPiInfo = namedtuple("RPiInfo", "type processor memory revision manufacturer flag")
LinuxInfo = namedtuple("LinuxInfo", "distro distro_pretty debian_based version version_codename")

Example

from linuxinfo import linux_info()
from linuxinfo import pi_info
from linuxinfo import RPiInfo, LinuxInfo  # not sure you need these
from linuxinfo.rpi import decode          # normally you don't use this!

# given a revision code, it decodes it (see below). Normally you
# wouldn't do this ... this is just a test
print(decode(0xa020a0))  # compute module 3
print(decode(0xa22042))  # Pi2B
print(decode(0xc03111))  # Pi4B

print(pi_info())  # reads /proc/cpuinfo and get revision code
RPiInfo(type='CM3', processor='BCM2837', memory='1GB', revision=0, manufacturer='Sony UK', flag='new-style revision')
RPiInfo(type='2B', processor='BCM2837', memory='1GB', revision=2, manufacturer='Embest', flag='new-style revision')
RPiInfo(type='4B', processor='BCM2711', memory='4GB', revision=1, manufacturer='Sony UK', flag='new-style revision')
