2 axis minature simulator best arduino library

MagicMike · Feb 17, 2014

I am trying to write the software to drive 2 stepper motors .Witch arduino library is suitable to drive my 2 tiny motors 28byj-48 but also and bigger steppers afterwards?

Im actually testing with a libary at the moment, AccelStepper.
But having issues getting the timing right as in the stepper needs time to position it's self before the new command for position can be achieved, for now motion is a little laggy, but further testing I should get there in the end.

/*
Using AccelStepper to control a stepper in SimTools.

*/

String inputString = ""; // a string to hold incoming data
boolean stringComplete = false; // whether the string is complete
#include <AccelStepper.h>
AccelStepper stepper(1,9,8);
int RPos = 0;

void setup() {
// initialize serial:
Serial.begin(9600);
// reserve 200 bytes for the inputString:
inputString.reserve(200);

}

void loop() {
// print the string when a newline arrives:
if (stringComplete) {
//Serial.println(inputString);
if (inputString.startsWith("R",0)){
//Serial.println("We have Right");
}
String valueString = inputString.substring(1);
RPos = valueString.toInt();
//Serial.println(RPos);

// clear the string:
inputString = "";
valueString = "";
stringComplete = false;
}
if (stepper.distanceToGo() == 0){
delay(5);
stepper.moveTo(RPos);
stepper.setMaxSpeed(4000);
stepper.setAcceleration(3000);

}
while(stepper.distanceToGo() != 0)
{ stepper.run();
}
}

/*
SerialEvent occurs whenever a new data comes in the
hardware serial RX. This routine is run between each
time loop() runs, so using delay inside loop can delay
response. Multiple bytes of data may be available.
*/
void serialEvent() {
while (Serial.available()) {
// get the new byte:
char inChar = (char)Serial.read();
// add it to the inputString:
if (inChar != '~'){
inputString += inChar;
}
// if the incoming character is a newline, set a flag
// so the main loop can do something about it:
if (inChar == '~') {
stringComplete = true;
}
}
}

This is just a side project for kicks as I use Jrks way easier to use.
