What is DDS slang? dds means in fb.
DDR (Data Direction Register) • DDR decides whether the pins of a port are. input pins or output pins. • If the pin is input, then the voltage at that pin.
This register is used to configure the PORT pins as Input or Output. Writing 1’s to DDRx will make the corresponding PORTx pins as output. Similarly writing 0’s to DDRx will make the corresponding PORTx pins as Input.
8051 microcontrollers have 4 I/O ports each of 8-bit, which can be configured as input or output. Hence, total 32 input/output pins allow the microcontroller to be connected with the peripheral devices. Pin configuration, i.e. the pin can be configured as 1 for input and 0 for output as per the logic state.
The Port B Input Pins address – PINB – is not a register, and this address enables access to the physical value on each Port B pin. When reading PORTB, the PORTB Data Latch is read, and when reading PINB, the logical values present on the pins are read.
DDR SDRAM is a stack of acronyms. Double Data Rate (DDR) Synchronous Dynamic Random Access Memory (SDRAM) is a common type of memory used as RAM for most every modern processor. First on the scene of this stack of acronyms was Dynamic Random-Access Memory (DRAM), introduced in the 1970s.
Introduction: Both DDR and GDDR are memories used for CPU and GPU respectively. DDR is used as system memory with CPU (i.e. Central Processing Unit) in your PC. GDDR memory is used with GPU (i.e. Graphics Processing Unit) to speed up performance of graphics card.
The Data Direction Register (DDRx) determines whether the pins operate as inputs or outputs. The port output register (PORTx) determines the actual value set on each pin when it’s being used as an output.
The ATmega32 has four 8-bit I/O ports named PORTA, PORTB, PORTC and PORTD, which are all general purpose and most have dual functions.
PIC 16F877 series normally has five input/output ports. They are used for the input/output interfacing with other devices/circuits. Most of these port pins are multiplexed for handling alternate function for peripheral features on the devices.
(1) (Input/Output port) An I/O port is a socket on a computer that a cable is plugged into. The port connects the CPU to a peripheral device via a hardware interface or to the network via a network interface. See port, standards – hardware interfaces, DisplayPort, HDMI and USB.
A pin is a physical connection for a single net. In schematics and HDLs, pin and terminal are used interchangeably to represent the the point where the connection to a network is made. A port is a group of pins representing a standard interface. In the physical world, a port is usually more than one pin.
The PORT register is the latch for the data to be output. When the PORT is read, the device reads the levels present on the I/O pins (not the latch). This means that care should be taken with read-modify-write commands on the ports and changing the direction of a pin from an input to an output.
GPIO stands for General-Purpose Input/Output.
PIND is the input register of port D (pins 0 to 7 on the UNO). That means you can use pins 2 to 7 on the UNO for your IR sensor, otherwise you have to change the port. To use pin 9, change PIND to PINB and irpin to 1.
The DDRD register sets the direction of Port D. Each bit of the DDRD register sets the corresponding Port D pin to be either an input or an output. A 1 makes the corresponding pin an output, and a 0 makes the corresponding pin an input.
First Information Report ( FIR ) recorded by police regarding cognizable offence is referred to as FIR while the other reports recorded in daily diary register are referred as DDR. F.I.R. … It is mandatory to give a copy of the first information report (as recorded by police) to the complainant or informant free of cost.

RAM is the memory your processor uses to store data on which it is currently doing some computation. VRAM is the video RAM on which the graphic processor store data on which it is doing computation. They are different on PCs which have discrete graphics processors.
What are the advantages of DDR4 over DDR3? DDR4 modules are more energy-efficient, operating only at 1.2V compared with DDR3’s 1.5V or 1.35V. The reduced power consumption gives substantial power savings and allows operation at higher speeds without higher power and cooling requirements.
(Graphics Double Data Rate) GDDR is double data rate (DDR) memory specialized for fast rendering on graphics cards (GPUs). Introduced in 2000, GDDR is the primary graphics RAM in use today. GDDR is technically “GDDR SDRAM” and supersedes VRAM and WRAM.
- Those that transfer a single item (byte, word, or doubleword) located in a register.
- Those that transfer strings of items (strings of bytes, words, or doublewords) located in memory. These are known as “string I/O instructions” or “block I/O instructions”.
The registers TRISA and TRISB are located in an area of memory called Bank 1. Normally, programs use the memory located in Bank 0.
Data must be written into port registers first to send it out to any other external device through ports. Similarly any data received through ports must be read from port registers for performing any operation. All 4 port registers are bit as well as byte addressable.
In AVR ATmega16 / ATmega32, there are three timers: Timer0: 8-bit timer. Timer1: 16-bit timer. Timer2: 8-bit timer.

Digital I/O pins: ATmega32 has 32 pins (4portsx8pins) configurable as Digital I/O pins. Timers: 3 Inbuilt timer/counters, two 8 bit (timer0, timer2) and one 16 bit (timer1).
TRIS is used to control direction (Input or Output) of each IO pin while PORT is used to Write or Read data from IO pins. … As in 16F, 18F also uses TRIS register to control direction of each IO pin. LAT register is used to write Output and PORT register is used read Inputs.
PIC microcontrollers ( Programmable Interface Controllers), are electronic circuits that can be programmed to carry out a vast range of tasks. They can be programmed to be timers or to control a production line and much more. … These are programmed and simulated by Circuit Wizard software.
It has 40 Pins. IT has 5 Ports in total. ( PortA, PortB, PortC, PortD and PortE).
An I/O configuration is the set of hardware resources that are available to the operating system, and the connections between these resources. Hardware resources typically include: Channels. ESCON/FICON directors (switches) Control units.
I/O ports allow for connections to hardware. This hardware could be internal or external. The ports are associated with copper circuits and memory ranges that allow the communication of data between the CPU, RAM, and the ports themselves. Common I/O ports include USB and FireWire.

In electronic design, a netlist is a description of the connectivity of an electronic circuit. In its simplest form, a netlist consists of a list of the electronic components in a circuit and a list of the nodes they are connected to. A network (net) is a collection of two or more interconnected components.
AVR® 8-bit microcontrollers control applications through their digital Input and Output (I/O) pins. These pins can monitor any voltage present as a high impedance input and supply or sink current as a high or low voltage digital output. These pins are usually organized in groups of eight and referred to as a port.
Each of the 9 pins usually connects to a wire. Besides the two wires used for transmitting and receiving data, another pin (wire) is signal ground. The voltage on any wire is measured with respect to this ground.
A write to a latch register is same as sending data to the port register PORTx. … Under such circumstances, the latch register will read the data held at the output latch and not the actual state of the pin.
Ping uses ICMP(Internet Control Message Protocol). it does not use TCP or UDP. To be more precise ICMP type 8(echo request message) and type 0(echo reply message) are used. ICMP has no ports!
Stands for “General Purpose Input/Output.” GPIO is a type of pin found on an integrated circuit that does not have a specific function. … These pins act as switches that output 3.3 volts when set to HIGH and no voltage when set to LOW. You can connect a device to specific GPIO pins and control it with a software program.
So effectively we can use 6 Pins as GPIO.
A general-purpose input/output (GPIO) is a digital data pin on a circuit (either an integrated circuit or electronic circuit board).
