Re: 1 ms too long for interrupts?

Oh cool, yes I too considered that but I wanted to add ADB to my legacy code (328). BTW, I didn't make any special arrangements to the v-usb to get it to work but I also don't have to read a sh*t ton of keys and only needed 3 commands each update;) FYI: I'm told linux will pull at 2ms with v-usb but...

Re: 1 ms too long for interrupts?

So to get what you needed, you had to make changes to the asmcommon, interesting. Thx for sharing, I would guess that was not you, unless the initials SG mean anything to you.

Re: 1 ms too long for interrupts?

Why are you talking about the ADB protocol? What is really strange about this, is that I just wrote a firmware driver for ADB last week but I never mentioned that in this post? It's like you can read minds LOL... That is crazy coincidental, I was just talking to a guy that did the ADP keyboard thing...

Re: 1 ms too long for interrupts?

Can you elaborate on this "If you synchronize to USB packets", this sounds interesting to me, unless you mean interrupt packets as a posed to bulk?

1 ms too long for interrupts?

I'm using a project that says one of its limits is The transmit routine disables all interrupts while a byte is being transmitted. For a typical 9600bps link that is approximately 1 millisecond. In some cases this might cause problems with interrupts which need urgent attention. Will v-usb handle th...

Re: v-usb with usb 3.0?

a) Everyone's USB 3.0 works fine?
b) Nobody cares?
c) "3.0" doesn't search correctly?

a) Get one person here to say V-USB works on a 3.0 port.
b) not many
c) its not an easy search no.

Re: v-usb with usb 3.0?

From what I here is buggy and will not work right. Also my project does not work on my 3.0 port. I can not find anything official on this, and I too would like to here from Christian on this.

Re: ACK to host

I don't quite follow you here but most of the communication is handled in;

usbFunctionDescriptor
usbFunctionSetup
and
usbFunctionWrite

If I knew more of what you were after I may be able to help.

Re: problem with windows 7

Yes it work fine, nothing is needed for changes. Check out USBLyzer (free trial) to see what the issue is. If you are using mega168/328/88 make sure you use 1/4 z-diodes.

Re: PC 2 V-USB

Sending data to the device has nothing to do with the schematic? To send data you need to use the usb write functions. There are a few examples on the forums here and even a data example (hid-data) is included in the samples from v-usb's downloads.

Re: usbHidReportDescriptor type of confilct

Sorry not clear why you need to change the device but consider.
0x09, 0x05, // USAGE (Game Pad = 05)
0x09, 0x04, // USAGE (Joy Stick= 04)

Re: usbHidReportDescriptor type of confilct

So did it all work out then?

I think this makes descriptors and comments as well. http://hidedit.org/

Re: Using V-USB VID and PID

Right changing VID and PID have 0 effect on how the device preforms. As mentioned run the code untouched, if that gives you the same errors, it's not what you did ;) If it seems to work without your changes then you are not changing the right values. Show us what you changed.

Re: usbHidReportDescriptor type of confilct

I'm really confused by your report here and what you are expecting? Your descriptor shows it needs 10 bytes( 2 analogs and 8 buttons), BTW buttons are normally done with one report ( 8 bits: a bit mask), I'm guessing you know that. EDIT!!! 0x95, 0x04, // REPORT_COUNT (2) <--- ahhh... see never do th...
