So a little update on the scaler project. I am in the final stages of assembling a counting program to simply display the output on a Mac. This program is using C++ assembly language to use the incoming data from the Yocto-PMW-Rx and modify its reporting behaviour.
Hz = CPS , edge count is divided by 2 to give raw Counts.
All this program is designed to to is display at the moment, no graphing or logging. Xcode has made this assembly process difficult as I can assemble it but cannot get the program to be freestanding nor display the incoming data.
The dependencies are listed on the top part of the C++ code.
If anyone has a background in C++ / programming would like to offer their recommendations I'm all ears. Eventually I'd like to be able to log and graph the output, maybe even be able to convert the CPS/ Counts to a metered dose. The raw counts could also be on a timer.
