QlockTwo - Die zweite

[Arkon]

Zur Zeit gibts es nur Fortschritte in homöopathischen Dosen.

Ich habe meine get_time-Funktionen erweitert um aus dem BCD-Code eine "normale" Zahl zu erzeugen:

unsigned char get_time_s() 
{ 
	i2c_start_wait(DS1307+I2C_WRITE); 
	i2c_write(0x00); 
	i2c_stop(); 
	i2c_start(DS1307+I2C_READ); 
	time_s = i2c_readNak(); 
	i2c_stop(); 
	 
	einer=time_s;
	einer&= 0x0f;

	zehner=time_s;
	zehner=zehner>>4;
	zehner&= 0x07;

	time_s = einer+10*zehner;

	return time_s;
}

Diese lässt sich auch auf dem LCD-Display ausgeben:

sprintf(buffer, "%i",time_s);
lcd_puts(buffer);

Allerdings kann ich damit keine Switch-Anweisung füttern. Bei

	switch(time_s)
		{
			case 0: 	COLUMN = (1<<C1);
						ROW = ~(1<<R1);
						break;
			case 2: 	COLUMN = (1<<C2);
						ROW = ~(1<<R1);
						break;
			case 4: 	COLUMN = (1<<C3);
						ROW = ~(1<<R1);
						break;
			case 6: 	COLUMN = (1<<C4);
						ROW = ~(1<<R1);
						break;

......

springt er immer in das case 0 -Ergebnis.

Hier noch der komplette Code
