Monitor voltage and current through Serial/USB port under linux

    I'm designing a device which will be powered off a battery which is in turn charged by a wind generator. I wish to monitor the power being generated by the wind generator and monitor the remaining power level in the battery.
    The system will be entirely DC.

    I need to monitor 1-2 voltage rails (both should be 12V or 1x12V and 1x24V), and read the current off one or both rails into a serial or usb port under linux.
    Does anyone know of a suitable device (probably a 2-channel ADC or similar with on-board UART)?

    I intend to read in this data and present it through SNMP traps for remote monitoring/loggin/administration.

    Not sure if this is any help, but I worked on something a bit like this before. It was about monitoring a DC voltage using a microconverter with serial output to a PC.

    We used a microconverter evaluation board, ADuC832. A bit expensive I know, but it's the only thing I can think of along the lines of an ADC with on-board UART. I don't know if there's a model with dual ADCs though.... :(

    Aye, I worked with ADuC812 last year.
    I don't have the time to write assembly code though :)

    Ideally it'd be a single-chip solution.

    I don't even know where to start looking.
