Arduino is an open source prototyping board which is made around ATmega328P; it has 14 GPIO (general purpose input output) pins, out of which 6 pins has capability to do analogue functions, all the 14 pins has the capability to digital functions. A USB 2.0 type B placed right corner of...
How to Use Milli in Arduino Code October 11, 2017 by Ryan Jones Delay statements are great and all, especially for their simplicity, but they can really put a damper on things when trying to multitask your Arduino. Forget delay and hop on the millis() train! Delay statements are ...
Finally, the loop function updates LVGL and the EEZ UI before hiding the currently inactive calibration points by calling a helper function, and it also updates the counter label in each iteration:Copy Code void loop() { lv_timer_handler(); ui_tick(); if (get_var_hide_repeat_button()...
Arduino Strings have been getting bad press due to the extra memory they use to make copies and the memory fragmentation they can cause. These can eventually consume all the available memory and cause the micro to miss-behave and reboot. This tutorial will show you how to avoid these two me...
Arduino For Loop: Easily repeat blocks of code saving processor memory and simplifying access to array data. How to Easily Avoid off by one errors.
Use theclock_gettimeFunction as Timer Benchmark in C Alternatively, we can utilizeclock_gettimeto achieve similar measuring goals.clock_gettimeis a more recent and recommended method employed in newer codebases. It stores the time value in thestruct timespecobject and takes the pointer to it as...
To do this, go to the “Power & Battery” tab in the left hand pane. Click the Calibration button at the bottom right. Enter the measured voltage in the popup box, then click Calibrate and it will ask to apply a new voltage scale. That’s it. ...
Arduino PulseIn Problem The problem with pulseIn is that you really want to use it with interrupts turned off for maximum accuracy. It is written in fixed assembler code that works by path timing measurement i.e. it works by assuming a 16MHz clock speed and measuring the number of assembler...
In order to create a delay, we must utilize the special timer registers of a microcontroller. Timer registers do just what the name implies; they keep track of time, by counting from 0 to a certain a number of clock cycles. By utilizing their ability to keep track of time, we can cr...
