The second is the floating light work. Connect the two types of LEDs to the Pic. In the former case, a source with the port out 25mA. In this case, the graph is connected to the chassis with a pice of the anode resistance. Port 1 is applied to the led lights up. The second type is that in the other end of a resistor, as ledin cathode is the positive voltage with pice, connects to. In this case, the led should only be applied to port 0.
#define LED PORTB
The Program should be flexible as you type to be written to the importance. Depending on the circuit elements of the project, especially as ports may need to be changed. Some of the changes, especially the printed circuit drawing too. This is done with the command #define to preprocessor definitions. It is similar to the descriptions you’ll see the button control applications. Microcontroller applications works be terminated as long as energy is in the circuit.
Therefore codes were written in an endless loop. Infinite loop in the first led to light the LED = 0xFE; with the expression by assigning the value of the first led is connected to the port LEDs FE cremated. LED = (LED < < 1) | 0 × 01; the expression also led a cremated the next. If the LEDs do not first assignment LED pice anodunu embodiment cathode bağlansaydı = 0 × 01; and in the loop LED = LED < < 1; expression should be used
So why not connected to ledin anode embodiment cathode pice? The answer to this PIC Microcontroller datasheet. Vdd be maximum current 250mA. But Vssden will pass the Max current 300ma.
