Of course replace the no-operation instruction with all the instructions you wanna perform in the loop. For the other loop conditions you can take a register of your liking. Je cloop1 Jump to content of the loop if metįor the for-loops you should take the cx-register because it is pretty much standard. The same loop in assembler: jmp loop1 Jump to condition firstĬloop1 nop Execute the content of the loop Loop1 nop Whatever you wanna do goes here Very often, these two work together thats why I discuss them here in the same section. If you just want to perform a very simple instruction a constant amount of times, you could also use an assembler-directive which will just hardcore that instruction times 4 nop Loops are useful when you want to repeat a block of code multiple times. Loop loop1 loop instruction decrements cx and jumps to label if not 0 If you just wanna to something 0-3=4 times but you do not need the index, this would be easier: mov cx,4 4 iterations That is the loop if you need to access your index (cx). Loop1 nop Whatever you wanna do goes here, should not change cx NumYellowBlinks = Serial.The same loop in 8086 assembler: xor cx,cx cx-register is the counter, set to 0 While (Serial.available()=0) //Wait for Input Serial.println("How Many Times Do You Want the Red LED to Blink? ") //Prompt User for Input PinMode(yellowLEDPin, OUTPUT) //Tell Arduino that yellowLEDPin is an output pin PinMode(redLEDPin, OUTPUT) // Tell Arduino that redLEDPin is an output pin Serial.begin(115200) // Turn on the Serial Port String yellowMessage= "The Yellow LED is Blinking" //Declaring a String Variable String redMessage="The Red LED is Blinking" //Declaring a String Variable Not equals to a b Checks if a is not equal to b < Less than a. Int numRedBlinks //Number of times to blink red LED The void loop() is a function that executes indefinitely until you power off the Arduino. Int numYellowBlinks //Number of times to blink yellow LED Int yellowOffTime=250 //Declare yellowOffTime an int, and set to 250 Int yellowOnTime=250 //Declare yellowOnTime an int, and set to 250 The result of a comparison of two values by a relational operator will either be true or false, for example is the value contained in a. The while loop would end once the condition. Suppose we initialized the ‘a’ with zero at before loop started then we. If ‘a’ is greater than 5 at any loop iteration, while loops will terminate. This loop will execute until ‘a’ is less than 5. Relational operators test the relationship between values, for example is the number 7 greater than the number 5 or is the value that a variable holds less than 10. Similar to the void loop, a while loop can loop through lines of commands, but its exit condition is more defined. In this loops condition is written in parenthesis like this while (a<5). Int redOffTime=250 //Declare redOffTime an int, and set to 250 Part 5 of the Arduino Programming Course. Int redOnTime=250 //Declare redOnTime an int, and set to 250 mseconds Int yellowLEDPin=10 //Declare yellowLEDPin an int, and set to pin 10 Int redLEDPin=9 //Declare redLEDPin an int, and set to pin 9 i wrote a code to drive a small Nema17 motor with a A4988 driver in full step. This example shows how to use a while loop to calibrate the value of an analog sensor.
