    everything.

    Thanks for the info,

    You might borrow the RUX or H701-compatible alpine HU from someone just to setup the presets, it's not needed for everyday use.

    I don't know anyone with one but maybe I can find one when he time comes.

    I got a bit mixed up here, but it looks like a carPC (windows based?) can control the H701 with this controller? If so, I need to save some pennies and pick one of these up. I have always wanted this ability and think it is the number one best innovation to come from this forum in a long time.

    Hi Nik,

    I've had an idea rattling around -thought I would see if it's desirable or possible.

    The typical use involves a PC to issue the RS232 commands your "wonder-box" will send on as AINET. All good!

    I cannot help think it would be useful to use some of the PIC I/O to create 2 direct control inputs: volume up / volume down. Directly controlled by the PIC with no external device needed.

    Why?

    There will be times you may be using a non-PC sound source, and it would be great to get use of the solution when the car-PC is off. The volume control button/knob in this scenario is then a control that always works.

    See - i've convinced myself! what do you think?

    If you're going to do that, why not have all of the PIC I/O's going to a header on the PCB, and have perhaps 2/3 of them pre-programmed for volume up/down and mute. That way, to add any other buttons, would be just a matter of wiring it in and programming it up.

    Why not indeed!? Reading the design document, it looks like there could be some I/Os on a header - quoted for IR/Relays/Switches, so could be programmed for direct control of volume ...

    Nik?

    Sorry for a long silence. Personal issues kept me away from the project, really hoping to finally complete boards and publish the code this week.

    I intentionally kept 4 AtMega I/O lines (PC2-PC5) on the header for future expansion. It could be used for input (check for specified voltage below 5V or for the ground pull up) or output with small current (50mA max).
    So yes, with small firmware tweaks those I/O lines could control the volume directly.

    It really does!! Considering the last many years fighting with nasty pops, ground loops and everything elese that comes with a computer direct to amps

    Its to bad Mitch stopped making the xm direct optical conversion kits, with this usb control thats in the works for the alpine and a little plug in to switch between optical inputs from the front end would be perfect!!!
