Endian format refers to how multibyte variables are stored in a byte-wide memory. In 'big endian' format, the most significant byte is stored in the first byte (lowest address). In 'little endian' ...

State machines help make seemingly large service routines short and simple to execute. There are a number of cases when decisions have to be made inside an interrupt service routine (ISR) and the ...

it is again written in C using the Arduino IDE. The frequency counter code is basically driven by the 1PPS interrupt. When a 1PPS interrupt occurs, the interrupt service routine responds by locking in ...

Interrupt Service Routine or an Interrupt ... the processor first executes these code that is present in ISR and returns back to state where it left the normal execution. digitalPinToInterrupt(pin): ...

Nano Sensor Interface * Arduino Nano (v3) in Sleep Mode * T.K.Hareendran/2018 */ #include <avr/sleep.h> #include <avr/power.h> int tgrPin = 2; // Trigger Input_Interrupt 0 Pin int drvPin = 13; // ...

A stepper motor and driver was wired up to the Arduino ... the call to an interrupt service routine. So there you are, and good luck. Hopefully, this article and the included code will be a ...

This technique do serve the purpose, but at the same time imposes a restriction that ISR (Interrupt Service Routine) should be generic enough ... In cases where software code is such that the ...

When an interrupt occurs, the CPU suspends the current task and executes some other code, which responds to whatever event ... mode stack and executes the corresponding interrupt service routine (ISR) ...

This saves code space and processor time during the critical early part of the Interrupt Service Routine. Interrupt bits are information for the firmware. Clearing an interrupt bit should cause no ...
