Objective Development Forums

got the same problem.
i hope someone of the developers knows anything about that.
i'm just wondering how to do a firware-based workaround and forced re-connect.
how could the avr detect, that it isn't properly connected?

I'm currently using an atmega8. It usually has 23 I/O Pins. I'm using an external 16 Mhz Quartz. Three Pins are reserverd for USB: one for triggering the interrupt (I think the attiny45 may need this third pin, too, so it has only 3 pins left) the other two pins are DATA+ and DATA- In my case that's...

You may use the Attiny45 as shown in the Project "EasyLogger" http://www.obdev.at/products/avrusb/easylogger.html That AVR is DIL-8 : Vcc, GND and 6 I/O Pins. If you use the internal RC-Oscillator and put two pins on the USB-Port, you still have 4 I/O-Pins for general purpose left. The fla...

Hi, I've made a console application for my project based on the project PowerSwitch. Everytime the console application connects with the device, it writes "found 4 busses" on the console. I bet it has something to do with the function "usb_find_busses();" but I can't find the fun...

Hi, I have problems with setting up the lock bits. The Makefile of the USBHID_Bootloader shows the value "0x2F" for the lock bits. But there are two problems with that: 1. As I look into the datasheet that can't be a valid value because the highest two Bits are always high. 2. I don't know...

hi,

to help you, we need some more information about your configuration.
Have you created an own project or is it based on another project? Do you have a shematic of your circuit? Have you tried to install libusb-win32 yet?

finally I've tested it with two red LEDs in series from DATA+ to GND and two LEDs from DATA- to GND. That works fine. The other solution was the method showed on the circuit of the USB-AVR home page with two normal diodes in series to reduce the voltage of the whole circuit to ~3.6 V. http://www.obd...

can anyone take a look at the circuit of PowerSwitch? http://www.obdev.at/products/avrusb/powerswitch.html I tried to change the circuit to run with red LEDs instead of Zeners. I'm using an atmega8 controller running with 5V @ 16 Mhz (quarz). Where do I have to place the LEDs to work in that circuit...
