Hello Everyone, my name is Fredrik.
I am new to this forum, and I want to ask you guys about a project I am working on atm.
I plan on making a test tool (or voltage sniffer) for monitoring voltage on multiple signals at once. The ECU I will be monitoring has up to 110 different inputs. My first idea is to build a device with 55 separate analouge volt-meters, and then be able to split the 110x inputs into two switchable channels. Then I can switch between the two channes and view all the inputs, without having to use 110x volt-meters..
The voltage I will be working with is between 0v and 30v. This to allow for some flex to monitor both 12 and 24v systems, as well as 0-5v poti inputs.
How can I make these two channels or groups of inputs switch to the volt-meters?
I have been thinking about several relays and one switch, but this really strikes me as a very spaceous setup.
I have thought about two inputs and one switch on each volt-meter. This probably is the most managable thing to do atm.
I have also looked into the posibillity of using a digital IO somehow, but I do not know quite enough about this yet.
Does any of you have suggestions for me about this?
I am not set on the idea of using so many separate meters, so if any of you know a way for me to monitor all the inputs on fex a single screen, this is very welcome!
Best regards
Fredrik
