Hello,
i am working on a project to measure and display ecg data on a pc GUI .
I am using ADAS 1000 and pic 24fj64gb002. I have been struggling with the code as it refuse to build.
Its been generating errors when building with Mplabx.
I will like advice on what mistake I am making.
Please find below the code I am working on.
Thanks
Tolu
