In addition to the Logic analyzer application for maximal performance and protection of your STEMLab board. Using the LA extension module is straightforward, just plug it on your STEMLab and connect the leads to the desired measurement points.
To use the Logic analyzer without the extension module (Logic Analyzer Basic) you need to be more careful in connecting the Logic analyzer probes to the extension connector E1 on the STEMLab board. The pins used for Logic analyzer board are shown in picture below.
Note: Directly using the GPIO expansion connector E1 pins of the STEMLab board only works with STEMlab 125-10! Picture below(left) shows the connection for the STEMlab 125–10 board.
