Port B and bit 7. bit 7 in DDRB controls the direction (input/output)

How to code Timers and Delays in Arduino - Forward

This article will show you how to control the Arduino IO pins faster, a lot faster. We all know we can use the digitalWrite() command to set an IO pin high or low. Before we do any mods lets do some measurement to see how long it takes. With a simple sketch to output a square wave on digital pin 2.

Arduino: Replace digitalWrite for 25x faster execution

The Arduino will of course not be churning data continuously because it'll be busy running the rest of the program, but using serial it is theoretically possible to send commands faster than …

Arduino - PortManipulation

On the Arduino, and all Atmel microcontrollers, processing is fast when using the Arduino IDE. But the input/output is very slow. If you have a time critical program digitalRead() and digitalWrite() can slow it …

How Arduino digitalWrite Works – and why AVR is Faster

/15/2012I have played with multiple pins for timing tests. Scope tests with the following five pin example show that a single call to writeGroup() takes 2. 5 microseconds. That is faster than a call to digitalWrite() for a single pin. It takes 80 microseconds for the loop to …

Fast alternative to digitalRead/digitalWrite - Arduino Forum

Why is the digital I/O in Arduino slow and what can be done about it? Jan But I still wanted to create a faster alternative to the Arduino digital I/O functions and when experimenting with various options, just this originally dismissed option proved to be the best one! you can just use the normal Arduino digitalWrite/Read without any

Benchmarking Arduino's digitalWrite() with a Logic

AVR Code. The Arduino environment is based on Atmel Atmega microcontrollers. The AVR language is a environment for programming Atmel chips. Manipulating ports and pins with AVR code is faster than using Arduino digitalWrite() function. It is also possible to make two pins change states at exactly the same time. You can read about it here.

Fast DigitalRead(), DigitalWrite() for Arduino: 5 Steps

So each style turned on the pin 500 times and turned it back off 500 times. digitalWrite() took 3804 microseconds, while the true c commands took just 348 microseconds. The true c commands are 10 times faster than the digitalWrite()! Try out this experiment for yourself, all …

Fast digital I/O for Arduino - CodeProject

If the pin isn’t connected to anything, digitalRead() can return either HIGH or LOW (and this can change randomly). The analog input pins can be used as digital pins, referred to as A0, A1, etc. The exception is the Arduino Nano, Pro Mini, and Mini’s A6 and A7 pins, which can only be used as analog inputs.
