 ==== Installing the old Adafruit LCD library ====
-As reported above, the new **Adafruit CircuitPython PCD8544** library is more CPU intensive than the old discontinued one **[[https://github.com/adafruit/Adafruit_Nokia_LCD|Adafruit Nokia LCD]]**. Fortunately enough, the old library does run with Python 3, and I was able to use it on my old Raspberry Pi model B over the operating system derived from Debian 11 Bullseye. So the average CPU usage is **lower than 10%**, instead than **above 30%**!

 The library is not available from the **[[https://pypi.org/|PyPI]]** repository, so it must be downloaded from the GitHub repository. The library depends upon **Adafruit_GPIO**, which in turn requires **Adafruit_PureIO** and **spidev**. The two Adafruit libraries are available from PyPI, for **spidev** we installed the Debian packaged version.
