LED-Dimmer
Für unseren Dimmer für LEDs benutzen wir insgesamt 3 Funktionen:
- Die Main mit einer Endlosschleife für ewiges hell und dunkel Dimmen durch Aufruf von den andern Beiden Funktionen
- Die Funktion my_wait(uint32_t time), welche einfach wartet
- Die Funktion dim(uint8_t ratio), welche für den schnellen Ein-/Ausschaltvorgang der LEDs zuständig ist
Die Main:
#include <avr/io.h> #include <util/delay.h>
#define F_CPU 2000000000L void my_wait(uint32_t); void dim(uint8_t); int main(){ DDRA=0xff; // LED ausschalten PORTA=0; uint16_t i=0; PORTA|=0x02; //Die Endlosschleife for(;;){ for(i=0;i<0xfff;i++){ // ein bisschen warten my_wait(1); // ein- und ausschalten // je größer i wird desto größer wird auch der Quotient der an bla übergeben wird // dadurch verändert sich auch der zeitliche Abstand zwischen dem Ein- und Ausschalten // wodurch die LED wiederum heller oder dunkler erscheint dim(i/0xf); } } PORTA|=0x03; return 0; }
Die Wait:
void my_wait(uint32_t time) { uint32_t i=0; for(i;i<(time);i++) //vordefinierte Funktion welche einen Leerlauf in Dauer von n Milisekunden auslöst _delay_ms(1); }
Die bla:
void dim(uint8_t ratio){ uint32_t i=0; // LED anschalten PORTA|=0x01; for(i;i<ratio;i++){} // LED ausschalten PORTA&=~0x01; for(i=ratio;i<255;i++){} }
