CNAS AIR-09: Support

[jordanch68]

Hello, I'd like to request Rad Pro firmware support for the AIR-09 geiger counter. The factory firmware is broken, it does not provide results in other units besides uSv even though it can be changed in the settings.

I can provide other details if needed, I think the firmware update process would be similar to the Bosean FS-5000 but that's just a guess. It came with a J305 tube and I measured the HV at 443V, this can also use a J321 tube and I tried that with the same results. It works, just needs better firmware. I've applied the Rad Pro firmware on my Bosean and GC-01 so I'm familiar with the process.

Thank you,
William C Jordan

I currently lack the time and motivation for what you propose.

This is what would need to be done:

• The original firmware of the device needs to be dumped, disassembled and analyzed to understand how the microcontroller interacts with its internal devices (input/output ports, timers, ADCs, etc).
• A schematics of the device needs to be created by tracing the connections from the microcontroller to the various components of the electronics board.
• Rad Pro's code needs to be customized for this device.
