    AT90USB Isochronous endpoints

    isochronous endpoint settings this could be a bad question, but what are these unhooked events which are reported by the compiler? How could they be hooked? Is it easy? I was thinking of a way to put the microcontroller into power down mode, i.e. to kill the oscillator by some command from...

    AT90USB Isochronous endpoints

    alternate setting isochronous endpoint It’s been a while I have been trying to make a bidirectional isochronous device, I manipulated the the descriptors and part of the main application (AudioOutput) to make a second isochrones pipe (IN direction). Then I made some drivers with Windriver...

    AT90USB Isochronous endpoints

    at90usb +examples Hi, for now It’s almost the STK525 I am using (something similar to that though because I have made the PCB myself and I’m using an At90UsB1286 with QFN package). Now you are quite right about the wrong jump to the address, because the bootloader could be launched correctly by...

    AT90USB Isochronous endpoints

    windows class driver which supports isochronous tha's nice Dean, thanks again, just like what you had said, I tried jumping to the start of the bootloader from one of the demos you have provided to us (I tried almost all the fuse settings of BOOTSZ with a verity of start addresses for...

    AT90USB Isochronous endpoints

    at90usb Hi Dean Camera First of all I should say I am very happy that you exist. As far as user friendliness, it’s marvelous. I figured out about the Isochrones demo in your superb USB library right after I had left my comments saying you had not provided any such example in your library. It’s...

    USB bootloader with AT90USB1286

    Now that’s great, by any chance does anyone know of any application software which could successfully jump to flash bootloader section if a certain data is sent via the USB? Could it be as simple as this? I loaded the DFU into the device and I inserted the following code in the application...

    USB bootloader with AT90USB1286

    I am using a bootloade sample code which turns at90USB1286 into a DFU class bootloader which works perfectly well with Atmel’s FLIP application under AVRstudio. Now my problem is that it only works just once and the apparent reason is that as I program the device with a USB flash application via...

    AT90USB Isochronous endpoints

    isochronous feedback problem I really didn’t mean to insist that MyUsb library is better than Atmel’s USB libraries for AT90USB devices, what seemed to me was that more convenient high level functions are available in this library and USB low level task is almost completely hidden looking from...

    AT90USB Isochronous endpoints

    at90usb example Does anyone know of any demo or usb library in which AT90USB1286/7 have been configured with Isochronous endpoints? I have used these 2 libraries so far : 1)http://www.fourwalledcubicle.com/wiki/Wikka/MyUSB...

    AT90USB1286,1287,646,647 and codevision USB library

    usb codevision the current version of the Codevision (1.25.3) does indeed support these devices, but it seems a library is needed to drive the USB controller on these devices. any hints?

    AT90USB1286,1287,646,647 and codevision USB library

    codevision usb hi everyone, i am writing C on atmega series with Codevision and i want to try AT90USB1286 for the first time. i have been through all the documentation on Atmel.com. I have viewed CDC and HID example codes for the device which have been provided in AVRstudio. Now the question is...

    help with pic18F4550 crystal

    configuration bits pic18f4550 The oscilloscope is a brand new 100MHz Tektronix with 1Gsapmle/sec. the supply line comes directly from USB bus and it measures precisely 5 volts, now I have been working with other USB peripherals in the same way, notably AVR_CDC and FT232 and I have experienced...

    help with pic18F4550 crystal

    pic18f4550 a 20mhz Good hint, I observed the crystal on a Digital oscilloscope and the 8 MHz sine wave is quite nice and stable, although the amplitude is somewhat weak (about 120mv p-p when observed with a 10x probe). Now the last thing I can do is that I put the code and the PCB project for...
