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 …
Playing with analog-to-digital converter on Arduino Due
Use Port Manipulation . First off, if you are using Arduino 1. 8x and a genuine Arduino development board, the digitalRead and digitalWrite functions are already running at a faster rate using port manipulation.
rformance - Arduino: faster alternatives to digitalread
Lesson 11: Arduino Circuit to Dim LED with Potentiometer. Arduino Circuit to Dim LED with Potentiometer” william says: February 14, 2015 at 9:01 pm I had a bit of a head scratch at the end of lesson 11 when you ask us to go and make the LED blink slower or faster depending on potentiometer…thought, “you should have explained more

/9/2015Arduino for STM32. Everything relating to using STM32 boards with the Arduino IDE. Skip to content. Its intent is to avoid the overheads of digitalWrite of course. . versions can be found here I'm not sure how much need there really is for writing any faster than we can do at the moment. i. e digitalWritefast was written because the AVR
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.
