Digital Input "Pull-up"?

[Stuhagen]

I am wiring a simple on-off switch to trigger a low boost (or high boost) condition. I am grounding one side and the other is the Digital Input. Do I need a pull up resistor to be "on" or "off. I assume the Vipec is an open collector design where the switch grounds the emmiter allowing current to flow to the collector. Just not sure if the pull up needs to be activated.

Hi Stu,

yes, set the pull-up to ON.

When you have finalised the setup, go to the Tuning tab,

Select Runtime Values,

Select the Digital Inputs Tab and toggle your switch On and Off, this will show active when ON.

This will confirm you have it setup correctly.

Look at you boost tables, with the switch off Boost Table 1 will say Active and Boost Table 2 will say Inactive.

Turn your switch On and boost table 1 will become inactive, Boost table 2 Active.

Thank you sir! This is a perfect answer. Thank for adding in additional instructions.

I do have 1 more question. Do I assume I use On Level = "High"? and Active Edge "rising" ?

[Dave Kriedeman]

Hi Stu,

ON LEVEL - LOW

ACTIVE EDGE - FALLING

[Stuhagen]

Tested and it works! Thanks. Now I need to figure out how to "link" the switch activation to the other 0 WG map.

Go to the Boost Control Tab,

Select, Multiple Tables Tab,

Select tables as 2

Below that is the Input to activate, select the Digital Input that you have wired your switch to.
