pysalx - scripts for interacting with the SciAps XRF and LIBS analyzers.

SciAps Analyzers

In sum, they are Android-derived 64-bit ARM systems. So they interact with standard free software Android tools such as "Android Debug Bridge" (adb).

Equipment:

Z-903 LIBS Analyzer

Operating System

Android. Kernel 3.10.49 dates to 2014, but it looks it is running their own patch/fork. There is android kernel source available from SciAps. Haven't check if it is complete/corresponding.

root@ngl:/ # uname -a
Linux localhost 3.10.49-g98ce14e #7 SMP PREEMPT Tue Sep 14 14:29:56 EDT 2021 aarch64 GNU/Linux

Installation

Tools to interact with the device are likely available in most free software oriented distributions, such as Debian.

Install on a Debian workstation (running as user debian, hostname workstation):

debian@workstation:~$ sudo apt update
debian@workstation:~$ sudo apt install adb

HOWTO

TODO HOWTOs

• Connect to device.
• Copy SD card data, such as samples and photos.
• Mount device.
• Initiate sampling remotely via USB and/or wifi.

Connect

You may need to set up permissions to access the device as non-root.

Run:

debian@workstation$ adb root
# If you don't have perms, something like:
debian@workstation:~$ sudo adb root

It should then say you are connected.

Listing Files

To see files, after connecting as show above. Examples:

debian@workstation:~$
