Olimex avr-usb-162 and CDC (LUFA)
Beta 2 didn't solve the problem.. Problem must have something to do with USB handshaking. If I don't send any bytes, AVR doesn't hang and Windows is able to open serial port. btw...

Looks like windows can't open serial port before AVR has sen't at least one byte?

Here is lowlevel version which works fine until I enable CDC_putchar call in main().

Yes, I made clean build. It can't be com port conflict because lowlevel demo works with same port? Found also that CDC_putchar doesn't work in lowlevel demo....

Ah! Looks like "lowlevel" version works - "ClassDriver" still fails.

It didn't help.. with this version Windows can't open USB virtual serial port.

Looks like it hangs to Endpoint_SelectEndpoint(CDC_RX_EPNUM);

Interrupt based all channels ADC in Atmega8

Interrupt based all channels ADC in Atmega8
Well.. the problem is that goertzel doesn't detect/filter frequency as supposed. Probably algorithm works but ADC reading doesn't? I'm linking against libm.

Ahh.. damn volatile. Usually gcc has handled globals as volatile, but seems that gcc-avr doesn't...

Hot Wheels Radar Gun serial interface
Just bought one from Germany and seems that it has slightly different connections than US version. At least trigger and battery level has been connected to different ADC. Radar...
