Hallo, guten Tag. Wer kennt bitte das DE0-Board ? Es ist bei mir Cyclone III : EPC16F484C6 Es kommt diese Fehlermeldung: Error (176310): Can't place multiple pins assigned to pin location Pin_K22 (IOPAD_X41_Y19_N14) Info (176311): Pin blue_out[0] is assigned to pin location Pin_K22 (IOPAD_X41_Y19_N14) Info (176311): Pin ~ALTERA_nCEO~ is assigned to pin location Pin_K22 (IOPAD_X41_Y19_N14) Wenn ich die Demo laufen lassen von der DE0-CD mit VGA dann wird dieser Pin_K22 nicht angemeckert obwohl er im Pinpalner geschaltet ist. Wird der hier irgendwie gebunden, das ich da nicht rankomme bzw den irgendwie freischalten muss? Mit dem De1 läuft das Programm. Danke. Gruss
