ArduinoJson is a JSON library for Arduino, IoT, and any embedded C project. It supports JSON serialization, JSON deserialization, MessagePack, streams, and fixed memory allocation. It has a simple API, it’s easy to use, and it’s trusted by thousands of developpers all over the world.
This library creates an 8-bit IO port for Arduino by combining any 8 Arduino pins. With this library, one can send/get direct 8-bit data.

Arduinolibrary for 8-bit IO port
Weall know that, the arduino gives digital output using “digitalWrite()”function and gets digital input through “digitalRead()” function. Butusing these two functions, it can give output or get input from any one pin - meansat a time it can give output to or take input from single pin only. If anyonewants to interface any 8-bit IO device like 7-segment display, DIP switches orDAC (Digital to Analog convertor) with arduino, it can not give direct 8-bitdigital output to device but instead it has to give output to 8 different pins.The data byte (8-bit) pattern is sent to different pins in form of 1’s and 0’s.for example if data byte is 37h (0011 0111) one has to send these 0 n 1 patternto 8 different pins using digitalWrite() function.
So toovercome this situation here I present 8-bit IO Port (input-output port)library for arduino. Using this library one can send direct 8 bit data to anyarduino board pins configured as a combined 8-bit port or can get 8-bit inputfrom these configured pins. This library clubs any 8 pins of arduino togetherto work as 8-bit IO port. Just one has to select any 8 arduino pins to becombined as 8-bit port and it has to configure its data direction as input oroutput. Data direction is set by character ‘O’ for output or ‘I’ for input.
Thelibrary has only 5 functions. There are two constructors that will create portobject(s), one function to send 8-bit digital output to port pins, one functionto get 8-bit digital input from port pins and one additional function to alter/ set IO direction of port. Here all 5 functions are explained in brief andthere after some examples are given with explanations.
1. IO_Port_8bit(int pin1, intpin2, int pin3, int pin4, int pin5, int pin6, int pin7, int pin8, char dir)
This is constructor. It will createobject(s) of this class and thus it will create one or many 8-bit port(s) by combiningdistinct arduino pins. One has to specify 8 different arduino pins to becombined as port along with data direction as input or output - means portworks as either input or output. The last argument dir in this constructor definesport works as input or output. If means port work as output and ifdir='I', port works as input. The same port cannot work as input and outputboth simultaneously or even alternatively. Also it indicates error if data directionis not selected
2. IO_Port_8bit(int pin1, intpin2, int pin3, int pin4, int pin5, int pin6, int pin7, int pin8)
Thisis another constructor. It will also create object(s) of this class and thus itwill create one or many 8-bit port(s) by combining distinct arduino pins. Onehas to specify 8 different arduino pins to be combined as port. But it does notspecify the data direction as input or output. After creating port object usingthis constructor, one has to set the port direction using set_IO_directionfunction. So this constructor allows programmer to alter port data direction inrun time using this constructor, the same port can work as input or outputalternatively (but not simultaneously)
3. set_IO_direction(char dir)
Thisfunction specifies the input/output direction of port. It has one characterargument that can be 'I' for port as input or 'O' for port as output. If datadirection is not selected, it displays error on serial monitor of arduino
4. send_8bit_data(int byt)
Thisfunction sends 8 bit data to specified pins. Just give int data (must be <255) as an argument that is directly given to 8 different pins. If data is>255 it displays error on serial monitor of arduino.
5. get_8bit_data(void)
Thisfunction gets 8 bit data from specified pins. It returns 8-bit int data byreading status of 8 different pins
Example1: blink 8 leds alternatively at a rate of 1 Hz
#include<IO_Port_8bit.h>
IO_Port_8bitmyport(2, 3, 4, 5, 6, 7, 8, 9, ’O’); //create output port
void setup() // nothing required in setup
{
}
void loop()

Maintaining updated Samsung GSM(3G) software prevents crashes and maximizes hardware and system performance. Using outdated or corrupt Samsung GSM(3G) drivers can cause system errors, crashes, and cause your computer or hardware to fail. Furthermore, installing the wrong Samsung drivers can make these problems even worse. Samsung gsm software.

myport.send_8bit_data(170); send data toblink all even LEDs

}
Example2: display binary counting pattern on LEDs from 0 to F
#include<IO_Port_8bit.h>
IO_Port_8bitmy8bitport(2, 3, 4, 5, 6, 7, 8, 9);//create port object

}

{
int i;
for(i=0;i<16;i++) //send data 0 to 15 to display
{ // binary pattern
myport.send_8bit_data(i);
delay(200);
}
}
Example3: indicate analog input voltage level on 8-bit LED bar graph display
#include<IO_Port_8bit.h>
IO_Port_8bitmyport(2, 3, 4, 5, 6, 7, 8, 9, ’O’); //create output port object
void setup()
{
myport.send_8bit_data(255); //blink all LEDs of bar graph once
delay(500);
myport.send_8bit_data(0);
}
void loop()
{
int level;
level = analogRead(A0); //read analog input voltage
level = map(level, 0, 1023, 0, 80);// limit thevoltage from 0 to 80
//increase or decrease bar graph level asper input
if((level<80) && (level>70))myport.send_8bit_data(255);
elseif((level<=70) && (level>60)) myport.send_8bit_data(127);
elseif((level<=60) && (level>50)) myport.send_8bit_data(63);
elseif((level<=50) && (level>40)) myport.send_8bit_data(31);
elseif((level<=40) && (level>30)) myport.send_8bit_data(15);
elseif((level<=30) && (level>20)) myport.send_8bit_data(7);
elseif((level<=20) && (level>10))myport.send_8bit_data(3);
elseif((level<=10) && (level>0)) myport.send_8bit_data(1);
elseif(level0) myport.send_8bit_data(0);
}
Example4: get 8-bit digital input from DIP switches and display value on serialmonitor
#include<IO_Port_8bit.h>
IO_Port_8bitmyport(2, 3, 4, 5, 6, 7, 8, 9); //create port object

Ufc 2 games download free game. As happens in real clashes, injuries and other types of damage are loaded from one fight to another, and neglecting the health of your fighter can make your time inside the ring is shortened.Unfortunately, the artificial intelligence of opponents is not exactly brilliant and don’t do a good job in making the exciting fights. Is now available and it’s free aswell!An interesting point in EA Sports UFC 2 Download PC is the way it determines the duration of the career of his fighter. Between one and another, you have to go through different types of training that ensures points that turn into improvements to the skills of your fighter — success in octagons also ensures new sponsors, items and options. So, it doesn’t take very long until the clashes thus become predictable and easy to be overcome, especially after you have already invested in substantial improvements to the skills of your fighter.With that, the real star of the game is its multiplayer mode, either offline or online (which relies on a system of categories similar to FIFA tournaments).

SoftwareSerial Library
The Arduino hardware has built-in support for serial communication on pins 0 and 1 (which also goes to the computer via the USB connection). The native serial support happens via a piece of hardware (built into the chip) called a UART. This hardware allows the Atmega chip to receive serial communication even while working on other tasks, as long as there room in the 64 byte serial buffer. The SoftwareSerial library has been developed to allow serial communication on other digital pins of the Arduino, using software to replicate the functionality (hence the name 'SoftwareSerial'). It is possible to have multiple software serial ports with speeds up to 115200 bps. A parameter enables inverted signaling for devices which require that protocol. The version of SoftwareSerial included in 1.0 and later is based on the NewSoftSerial library by Mikal Hart. LimitationsThe library has the following known limitations:
If your project requires simultaneous data flows, see Paul Stoffregen's AltSoftSerial library. AltSoftSerial overcomes a number of other issues with the core SoftwareSerial, but has it's own limitations. Refer to the AltSoftSerial site for more information. Examples
