Aşağıdaki programa 2 küçük ekleme yapmak istiyorum ama başaramadım abilerim bi el atarmısınız
-0,1,2,3 bitler çıkış
-tüm çıkışlar 0
-tüm çıkışlar 1
-0. ve 2. biti söndür
-1. ve 3. biti söndür
-2. ve 3. biti yak bekle.

*
* The LEDs are connected to input-outpins (I/O) RC0 through RC3. First, the I/O pin
* must be configured for an output. In this case, when one of these pins is driven high
* (RC0 = 1 ), the LED will turn on. These two logic levels are derived from the power pins
* of the PIC MCU. Since the PIC device?s power pin (VDD) is connected to 5V and the
* source (VSS) to ground (0V), a '1' is equivalent to 5V, and a '0' is 0V.
*
*
* This turns on DS1 LED on the Low Pin Count Demo Board.
*
* PIC: 16F1829
* Compiler: XC8 v1.10
* IDE: MPLABX v1.50

* Board: PICkit 3 Low Pin Count Demo Board

TRISCbits.TRISC0 = 0; //using pin as output
LATC = 0; //clear all pins to 0
LATCbits.LATC0 = 1; //turn ON the LED by writing to the latch

Tris, Port ve Lat komutlarını 0b ile başlatarak
bit halinde veya bit tanımlamasıyla yaparsanız
işler kolaylaşır.
İlgili mcu nun kataloğunda giriş ve çıkış nasıl
yapılacağı, portlara nasıl çıkış verileceği yazmaktadır.
Mesela;
LATA = 0b10101010;
ya da;
LATAbits.LATA5 = 0b0;
