AIN/DIN

info

The following variables are located in the /common folder.

note

Difference between GPIO, AIN and DIN :

• GPIO - high precision, usual reading voltage range is 0-10V, can read negative voltages, can be individualy configured with pull-up or pull-down resistors, can capture pulses (PAS, speed sensor), can be optionally used as an output, is typically isolated from the power stage.
• AIN - usual reading voltage range is from zero up to the battery voltage. It is not isolated from the power stage.
• DIN - a digital state of the physical DIN/ODIN input (if present) or digital representation of the AIN input (if present).

States

ain [10mV]

Reading of AIN inputs, representing the analog voltage.

info

AIN inputs are present only in the SL controller.

din

Digital state physical DIN/ODIN inputs or, digital representation of the AIN inputs, where the threshold for logic 1 is set by the adin_thr parameter.

vspl [mV]

Internal voltage of the power supply for the I/O module.

info

This is a diagnostic measurement and only available in certain devices.

Parameters

info

AIN inputs are present only in the SL controller, therefore the following parameters are only present in this device.

adin_thr [10mV]

This threshold defines the decision level for converting analog reading of ain to the digital, bi-state value of din.

pupd

assigns the global pull-up or pull-dn resistors to all the AIN inputs.

pupd value	Description
0	floating (~47k pull-dn)
1	pull-up (~100k pull-up)
2	pull-down (~32k pull-dn)
