GeigerLog on Raspberry Pi

The Raspi has received a major update of its operating system, now called Bullseye. I updated my Raspberry Pi 4 Model B (2 GB RAM) with the 64 bit version and installed GeigerLog. First impression shows notable improvements.

I will offer some Raspi specific instructions and code, which will all be hosted in this location.

Using Raspi as GeigerLog WiFiServer Device Version 2.0

This is a major update to the previous version, establishing a promintent role for the Raspi as a data hub. So I think.

This version not only supports the GMC counter (slightly updated), but now also the use of I2C devices (with an LM75B sensor), and the use of pulse counting via Raspi Hardware Interrupt, done with the CAJOE counter as Demo. Took some fiddling with the hardware.

All works well!

Using Raspi as GeigerLog WiFiServer Device Version 1.0

A Raspi can be used to WiFi-enable a device, which natively has no WiFi, and make it an efficient WiFiServer Device for GeigerLog by running a simple Pythpn script on the Raspi. As example, a GQ GMC-300E+ Geiger counter is connected to a Raspi, and now performs well as WiFiServer.

Installation

The installation has also become easier, though it is not yet fully the Linux standard. I have therefore updated my installation instructions in the manual specifically for Raspi, and I am posting this chapter for download as UPDATE Raspi Installation for GeigerLog-v1.3.pdf.

Raspi Regressions

Unfortunately there is a regression in the Raspi font handling, which for GeigerLog results in a disorganized printout to the NotePad and other places. A workaround is provided with the FONTFIX Raspi GeigerLog 1.3. Just download, unzip and copy file ggeiger.py over the existing file.
