Hi there.

I know this may seem sort of silly asking someone who has made, at its core, a Linux API, but I'm having serious issues trying to get M4 ATX monitoring working on Windows 8.

Yes, I know, Windows 8. The drivers for the M4 ATX PIC18F2450 don't work - Windows detects a USB device, not the virtual COM port, and the far newer Microchip drivers don't seem to work any better.

Since you wrote the Linux API, I wondered if you might be able to assist me in getting M4 API software working under Windows 8.1 with a driver - since Mini Box are pretty insanely difficult to communicate with (I don't think they know why it doesn't work) and wherever else I've asked, no one has been able to give me a conclusive answer on why this isn't working. The existing M4 API software for Windows is as good as useless for debugging because it has no configuration, everything is just greyed out if the device fails to connect.

I don't really mind what format I get the output in, if it's directly a command line readout I won't mind, I can add a UI of my own later on. I really, really need to get this monitoring working though, otherwise I can't give battery life readouts nor properly configure the shutdown for the ATX board.

Thanks

Trying to figure out what M4-ATX power supplies actually are, I noticed that these hyperlinks in the README file are no more valid:

I have built a new machine using the Mini-Box M4 ATX PSU and trying to use m4api. After obtaining two prequisites, I had no problem with any of the steps:

$ mkdir -p build
$ cd build
$ cmake ..
$ make
$ sudo make install

Once I try to run the command "./m4ctl -config" or any of the other suggested lines, it just hangs and does absolutely nothing.
