Moppa,

I've been working on getting power switch to work on a 328p. I am using usb data pins on port d 2 and 4 and a single LED on PC5. I am using a 16Mhz crystal. I have a usb boatloader on the chip so know the usb works with the crystal and fuse settings. What did you change to make it work for your 328p?

Thanks

HIDKeys on Atmega328P

2010-12-20T19:42:31+02:00

Hello!

I've got my Atmega 328P up and running with the Powerswitch project and it is working flawlessly. Some tweaking had to be made so it used the correct pins and i had to flash the fuse bytes. When i connect it to my linux computer it says

Code:

kernel: usb 2-2: new low speed USB device using uhci_hcd and address 78

once (as it should) and then i can send commands to it using the command line program. Great!

But now i wanted to get the HIDKeys project running and I seem to be out of luck. I'm using 12M external osc and 2 rectifier diodes for level conversion (this worked in the Powerswitch project). I've edited mmcu flag so it says mega328p in the Makefile. The code compiles fine, but when i connect the project then i get the following:

Code:

kernel: usb 2-2: new low speed USB device using uhci_hcd and address 90
kernel: usb 2-2: new low speed USB device using uhci_hcd and address 91
kernel: usb 2-2: new low speed USB device using uhci_hcd and address 92
kernel: usb 2-2: new low speed USB device using uhci_hcd and address 93

And when i connect it to a windows computer i get the Device unknown message.

Can anybody help?
