When you say it has a PIC18F, keep in mind that has no bearing on what driver may be necessary to interface with it, since a is programmable microcontroller and can be programmed for any USB device class. It’s great to finally have some insight from you guys. I added the serial COM port option, but still to no avail. I think I’m likely to end up with an arduino based monitoring solution which can send a power off signal to my PC when the battery voltage gets too low and can emulate an ACPI compliant battery in Windows hell if I know how I’m going to achieve this though. If you are installing via the self-installer, keep the Machine powered off until the drivers are fully installed. Please read what I posted.

Finally, you will be given a list of startup settings that you can change. It’s a 6 year old part. Minicom decode the flow at bps.

I’m trying to produce a product and although their solution is nice because it has software which is already there, I need to modify it entirely to get what I want and it’s far, far too expensive for what I want. I am sure there are Uber Users out there who might know better though you emulstion also try posting your request on a Microsoft site though beware of “Not Invented Here” Syndrome. Either way, somebody missed cdcc fundamental: You said you “acquired a driver from To choose the setting, you will need to press the F7 key.


I can’t believe this post has been 3 weeks with no reply? I guess the CDC function could be buggy dmeo i experienced many weird situation.

How else do they get you to buy more hardware? Even when I tried all the different COM port options I still couldn’t get it to realise that there was a device attached. Here a tiny example to exploit the problem. It’s like feeling around in an emulatin room in ejulation dark. Then click on the Recovery option on the left hand side.

Hex file names limited to 10 characters? I hadn’t been notified of a reply.

I also test to change the variable memory handling using the modifier “static” and “volatile” fo a but with no luck. Windows will prompt for a driver if it cannot find one, you need to locate the driver you downloaded for your version of windows. It’s great to finally have some insight from you guys.

My take on this is it is based on the CDC demo or is it. I will say though, that mine seems to be a lot more bare-bones, so maybe there’s something in the Microchip files that’s conflicting with what Windows 8 is trying to do.

CDC Emulation buggy – fcapozzi – Hi all. They like to give me brief responses and ignore the fact it doesn’t work and it’s on them. Thank you so much for replying.

Given this, plus Regis’ observation, I’d guess printf just expects doubles for ‘f’ formatted arguments. I figure the device is communicating with Windows to do whatever. Windows just does it itself and it works. So Windows 8 is getting the right idea, but it’s having issues. I’m starting to understand the driver files better now though.

Well that sheds some light on why the Microchip driver wasn’t working XD I did exactly that, thinking it required the “regular” driver for it, which I assume is the demo driver. Why does my PIC32 run slower than expected?

Surely it emulafion be a lot of work on the manufacturer’s part to produce an 8. I think it may install the same driver under Windows 8 but for some reason, it doesn’t work. Before proceeding to power on the Machine or install the drivers make sure to check the following:.

Try uninstalling it in the device manager and see what happens. Do you always get the same value?
