 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%**! 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]]**.
