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

At what frequency/rate does the digitalRead function read

What are the fastest alternatives to calling the Arduino functions digitalread() and digitalwrite()? Arduino: faster alternatives to digitalread() and digitalwrite()? $\begingroup$ What are the fastest alternatives to calling the Arduino functions digitalread() and digitalwrite()? AVR-specific or chip-specific solutions are acceptable

Speeding Up Arduino - stackabusecom

The fastest I can get it through USB/serial is about 14KB/s using a baud of 115200. The data corruption rate is also a little too high with this method (maybe 0. 3%, need it to be more like 0. 01%). My computer can spit out data at USB2. 0 speeds if necessary, but the Arduino is …

Playground. arduino. cc will be read-only starting December 31st, 2018. The development of this library began with the need for a way to quickly and easily set the PWM period or frequency, but has grown to include timer overflow interrupt handling and other features.

Password In the Arduino implementation of digitalWrite and digitalRead there is a check whether the affected pin is used by a timer. It seems 'silly' to do this each time a pin is written or read - as the Arduino

How exactly slow is digitalRead()? - Arduino Forum

First things first, I came up with the idea because of pure boredom. As you can, obviously tell from the title of the project, that it is a reaction . You can play it alone or with friends. The only player limit is set from the pins of the Arduino. I kept the design and wiring simple. You can use it on, I …

Robotics with Arduino - Storming Robots

Arduino users know that the pins are labeled as digital 0-13 and analog 0-5. The makers behind Arduino used this for simplicity. The actual ATMega chip’s pins are labeled differently, however. Each pin has an assigned letter and number. The numbers range from 0-7. …
