I'm working on this waste management system that notifies when the garbage bin is full. The Central Unit notifies for a garbage pickup. When the garbage is picked up, the bin notifies the central unit that it has been emptied. I have to save this pick-up data in a csv. One column contains Bin ID, the second column contains the vehicle regstration number of the truck that picked up the garbage and the third column contains time and date of the pickup. Now the Labview VI seems to be doing, almost what I need. It does save the data, but it also leaves a bunch of cells empty in the spreadsheet! Also I have three string indicators that need to display the data (Bin ID, Vehicle Reg. No. and Time & Date) of last bin that was emptied. Could you guys help me find out why it's leaving blank cells? Why it's not displaying the data on the string indicator?
