Array and Channel Group function, Matrix function

This is what one of my code look like. Do you think this looks well organized/planned and/or readable?

Part of the problem is that we are collecting a lot of information from an external device and it needs to be distributed. It would be extremely useful if we could group signals into Channels(record) which would allow the efficient transfer of data from one function group to another without having this humongous plate of spaghetti, It would be wonderful if the receiving module would automatically inherit all the sub elements without having to recreate them.
Array/Matrix operation. Like wise it would be nice to have the ability to manipulate large quantity of data of the same type. We are dealing with Lithium batteries. We have 120 cells and 120 temperature data point to manipulate. Do you know how long it takes to create the code to read the incoming CAN messages to collect the data and then display them in groups? And God help you if you made a mistake and need to re-organize it. And forget about trying to calculate min/max and average. In almost any other language a for to loop and an array structure make dealing with such items a breeze.
