Kann mir den Code jm. erklären??
Hallo!
Im Tut der Nibobee(http://download.nicai-systems.com/ni...e_20091123.pdf)
gibt es das Programm PINGPONG das mich als Einsteiger sehr überfordert!
Kann mir den Code jm. erklären??
DANKEE!!!!!!!!!!!!
Code:
#include <nibobee/iodefs.h>
#include <nibobee/led.h>
#include <nibobee/sens.h>
#include <nibobee/delay.h>
enum {
STATE_IDLE = 0,
STATE_PULL0 = 1,
STATE_PULL1 = 2,
STATE_KICK = 3,
STATE_PUSH = 4
};
uint8_t calculate_state(uint8_t state, int8_t sensor) {
switch (state) {
case STATE_PUSH:
case STATE_IDLE:
if (sensor==-1) {
return STATE_PULL0;
} else if (sensor==+1) {
return STATE_PUSH;
}
return STATE_IDLE;
case STATE_PULL0:
if (sensor==-1) {
return STATE_PULL1;
} else if (sensor==+1) {
return STATE_PUSH;
}
return STATE_IDLE;
case STATE_PULL1:
if (sensor==-1) {
return STATE_PULL1;
}
return STATE_KICK;
case STATE_KICK:
return STATE_IDLE;
}
return state;
}
int main() {
led_init();
sens_init();
uint8_t ball_pos = 3;
int8_t direction = -1;
uint8_t state_l = STATE_IDLE;
uint8_t state_r = STATE_IDLE;
while(1==1) {
delay(100);
state_l = calculate_state(state_l, sens_getLeft());
if( ((state_l==STATE_PUSH) && (ball_pos==1)) ||
((state_l==STATE_KICK) && (ball_pos==0)) ) {
direction = +1;
}
state_r = calculate_state(state_r, sens_getRight());
if( ((state_r==STATE_PUSH) && (ball_pos==2)) ||
((state_r==STATE_KICK) && (ball_pos==3)) ) {
direction = -1;
}
if(direction==+1) {
if(ball_pos<3) {
ball_pos++;
} else {
direction=0;
}
}
if(direction==-1) {
if(ball_pos>0) {
ball_pos--;
} else {
direction=0;
}
}
led_set(LED_L_YE, ball_pos==0);
led_set(LED_L_RD, ball_pos==1);
led_set(LED_R_RD, ball_pos==2);
led_set(LED_R_YE, ball_pos==3);
}
return 0;
}

Ich hab den Thread-Titel geändert und dir zwei Code-Tags aus meiner privaten Schatulle spendiert. (PicNick, Mod)
