AVR-Stick – News

Salut à tous !
Voici le code source de mon hello world avec une board AVR-Stick de sparkfun.
Requiére la librairie vusb (dossier usbdrv !)
En espérant que cela va donner des idées à certain 😉

Tester et compiler sous winavr :
> make
> make flash
Petit bug bizarre le Hello World c’est transformé en Hello Zorld (W->Z) pourtant les tables hid sont juste, allez savoir pourquoi …
Edit: Ce n’est pas un bug en fait … qwerty power ! Et oui j’avais oublié mais les tables hid sont pour les claviers qwerty c’est bête hein !

AVR-Stick ->
Petit conseil : Coller un morceau de limande souple en dessous du connecteur usb pour le rendre plus épais et mettre un peu de soudure sur les connexions pour les rendre plus solide ;).

 * is the Start Of Frame signal (a single SE0 bit) available immediately after
 * a USB RESET. We first do a binary search for the OSCCAL value and then
 * optimize this value with a neighboorhod search.
 * This algorithm may also be used to calibrate the RC oscillator directly to
 * 12 MHz (no PLL involved, can therefore be used on almost ALL AVRs), but this
 * is wide outside the spec for the OSCCAL value and the required precision for
 * the 12 MHz clock! Use the RC oscillator calibrated to 12 MHz for
 * experimental purposes only!

    optimumDev = x; /* this is certainly far away from optimum */

        x = usbMeasureFrameLength() - targetValue;
        if(x < 0)
            x = -x;
        if(x < optimumDev){
            optimumDev = x;
            optimumValue = OSCCAL;
    OSCCAL = optimumValue;
Note: This calibration algorithm may try OSCCAL values of up to 192 even if
the optimum value is far below 192. It may therefore exceed the allowed clock
frequency of the CPU in low voltage designs!
You may replace this search algorithm with any other algorithm you like if
you have additional constraints such as a maximum CPU clock.
For version 5.x RC oscillators (those with a split range of 2x128 steps, e.g.
ATTiny25, ATTiny45, ATTiny85), it may be useful to search for the optimum in
both regions.
