TS-8820-leds
From embeddedTS Manuals
The TS-8820 has 27 LEDs used to indicate the electrical status of the inputs and outputs on the device. LEDs are labelled as "LED#" on the PCB silkscreen.
The majority of the LEDs are not able to be directly controlled, they turn on or off as a reaction to the status of the I/O they are connected to. For example, when DIG_OUT1 is set, LED17 will turn on. The "System" LEDs are the exception to this and are controlled via the SoM LED interface.
