As stated on the previous page reportBuffer [ 3rdrow ]=0b00010000;//ps home pressed. ( or 0b00000000 ) not pressed I dont have your descriptor but whatever your third row is button is. It's just the last button in the packet. This only works if the conditions are met as I listed above. buttons are c...

You need to included the usb descriptor. I think raph puts its in devdesc or gampad h files.

You also have not added the code in the usbFunctionSetup?

Did you change anything? I can;t write the code for you but if you take a shot at it I will help.

There is no simple solution just a lot of gotchas. Most of what you need is in this post. 4 main things need to happen. 1) usb descriptor must have buttons on first 3 reports. 2) third report is home button reportBuffer [ thirdrow ]=0b00010000; 3) you must reply to the controller request in the usbs...

All of my issues were related to the global int flag. and this https://forums.obdev.at/viewtopic.php?f=8&t=10981 I was using a combination of atomic and cli to control int's. Now I just start and stop my INT0 directly and only, this allows use of interrupts to work fine for my code that needs it...

It's ok, I solve my issue last night. My main issue was USB_PROP_LENGTH(12) needed USB_PROP_LENGTH(24). Thx for the link, I'll check it out and see if we used the same approach.

Yes, I'm doing it.

You should do 132 bytes for report out not 128. What I do is always use 128, in or out. For in I need to added the few bytes for address and what not (132) but its always the same. That's what I said, you just cut off the part of my text that said 132 In your API while you connect to your device, y...

normally you just keep a counter as shown in the examples but you can also...

What watt diodes do you have on the +/- leads.

how can I make this dynamic. I need to set my product string via eeprom for a project I'm using. tried #define USB_CFG_DESCR_PROPS_STRING_PRODUCT (USB_PROP_IS_RAM | USB_PROP_LENGTH(12)) and #define USB_CFG_DESCR_PROPS_STRING_PRODUCT USB_PROP_IS_DYNAMIC | USB_PROP_IS_RAM) both allow the code to work....

IS there a way to stop the usb interrupt without using cli? cli causes lots of memory move issues that requires the ATOMIC_BLOCK for avr. I'd rather just disable usb ints then all.

I did sum sniffing and its a pid stall. When a device receives a request that is undefined, is inappropriate given the current setting or state of the device, or uses values that are inappropriate for the particular request, then a Request Error exists. The device handles a Request Error by returnin...

I'm trying to send data to my device via the usb.dll usbSetReport function. I set up my usbFunctionWrite to watch for my report ID then a command on byte 2. I return 0 to tell the driver to expect more (bytesRemaining). This most of the time works but some times dies. When it dies it just stop and d...

Not sure if anyone else here ran in to this but you can not use either the commend or gui tool to flash more then %87 of the mega328 code. The NRWW is apparently in the way. If your main project is under %87 used flash, it works fine. Once it hits 7800 it will die. See the link below for the detaile...
