This is an Arduino timer interrupt that fires when a Timer1 capture event occurs. As you can see there are many interrupt vectors and you should look at the datasheet to see what they are used for in each hardware module.Scroll down and you get to the two more useful (for this ...
Serial.println(F("Benchmark Time (microseconds)")); delay(10); Serial.print(F("Screen fill ")); Serial.println(testFillScreen()); delay(500); Serial.print(F("Text ")); Serial.println(testText()); delay(3000); Serial.print(F("Lines ")); Serial.println(testLines(GC9A01A_CYAN))...
For a traditional oscilloscope, the rise time is tr = 0.35/f. For your 18kHz bandwidth, that gives a risetime of something like 19uS. So your slew time of a couple of microseconds shouldn't be an issue. Finally, I ought to say...
Run the following command to capture data, but make sure you are not capturing from the Arduino IDE 2; otherwise, the device will be locked: $ minicom--capturefile=$HOME/Downloads/ultrasonic_sensor_cap.txt--baudrate9600--device/dev/ttyUSB0 See itin action: But that is not the only way...

The LMIC has embedded optional calls to capture debug information that can be printed out later, when the LMIC is not active. Logging is enabled by setting LMIC_ENABLE_event_logging to 1. The default is not to log. This C preprocessor macro is always defined as a post-condition of #...
How to use Arduino to create a sound-triggered flash that will allow you to capture action shots that freeze time.
How to use pulseIn() Function with Arduino. Learn pulseIn() example code, reference, definition. Reads a pulse (either HIGH or LOW) on a pin. Return The length of the pulse (in microseconds) or 0 if no pulse started before the timeout. What is Arduino pu
If you care to know, the code uses the Arduino's 2 external interrupts to capture when the Rx signal pin changes states (goes from HIGH to LOW or vice versa), when it does at the beginning of each signal, it calls the interrupt function which reads the digital state of the pin and ...
Before we dive into the serial capture, let's revisit the compile size. I got 2516 bytes, this time- 28 bytes more than usingintand 58 more than usingbyte. Still a pretty small difference but a difference nonetheless, and a difference which could add up if you do a lot of math with...
