Hi, I'm trying to compile the bootloaderHid's command line tool (BootloadHID.exe) and seem to be missing some information. I tried to download ddk 7 and I see its not the same as the ddk that was used. files are moved, and identifiers are missing. Is there any information out there on how to build t...

Can anyone here help me find a place to get PIDS? As a holiest I only need a small number of them. The sites I do find, claiming to sell them, turn out never to reply.

Here is a generic 8 button x,y hid. I never have a single bit of trouble with it. const char generic_usbHidReportDescriptor[] PROGMEM = { 0x05, 0x01, // USAGE_PAGE (Generic Desktop) 0x09, 0x05, // USAGE (Game Pad) 0xa1, 0x01, // COLLECTION (Application) 0x09, 0x01, // USAGE (Pointer) 0xa1, 0x00, // ...

Hi , I know its been a bit here, but any luck with this. I just started the same venture to day. Plan on doing the same thing as you..


Ok, I got it to work. Look like you no longer are a member? but took a few hours to get it work so if you return one day look me up.

Yes, I personally find it extremely frustration, confusing, and lonely. Not only can I not find working examples, people point blank dont answer questions on the matter, hence I dont think its just me.

Roughly how long would it take to implement V-USB on an ATmega8/32/64? I have a lot of AVR experience but none with V-USB. I have done USB on non-AVR MCUs and also on the AT90USB1287 (LUFA). - I had 0 experience with avr and usb-v . With the examples they have it only took me 1/2 a day. And most of...

One possible thing to look at is the time during usb write to device read. If the avr takes too long to work with the device the usb may fall behind. Not sure about the details here but I have made this mistake before and the result as you described.

Yeah I know it sounds a bit weird but here is what I'm pondering. I wan to create an adapter that accepts a usb connection. And processes out the descriptor data. This is mainly for a HID joystick, but I imagine its the same data that I'm after in any case, keyboard, mice...etc. I want to get this i...

Great, thx!

dup, sorry.

I'm using an interrupt for pin-change and I wanted to disable the usb int for a short while, how can I do that without using disable all interrupts?

No, for the v-USB to work you only need a usb port Now getting the avr-studio and your ISP to work will involve some drivers. But if you write for example a HID and interface it with some hardware there is no need to install a driver as widows/linux will understand a HID descriptor.

Just want to make sure I have this understood right is this right cli() //doing stuff here will be done with the usb interrupt disabled // you have 25 clocks to do what you need with a 12mhz sei() also what registers are safe? I found this helpful guide m under "What registers are used by the C...

Doesn't look like you could do it w/o extra hardware to split the clock & data signal But then, it's late and I could easily miss something.. meh, yeah 2 shift register would be best, but I know one other guy that did it with one avr. He decided to keep his code a hush though. I know when the s...

You know I thought about this after seeing the psx2 project. Personally I feel the SPI could be used for this but not sure how I could get it to work. The device I'm talking to uses a two line async serial bus. The two serial data lines alternate between clock and data every bit. Would I be able to ...
