Hi everyone!
I'm facing some trouble with my project, it's basically a stepper motor connected to the big easy driver and onto the arduino board with two push buttons for forward and reverse motion (BRed and BWhite, respectively). When I execute, the motor automatically rotates when connected to the power supply. However, this only happens when I include the else if code for the reverse motion. When it is excluded, the motor waits for my input (BRed). Can anyone help?
This is my code.
//Declare pin functions on Arduino
#define stp 2
#define dir 3
#define MS1 4
#define MS2 5
#define MS3 6
#define EN 7
#define BRed 8
#define BRedenabler 9
#define BWhiteenabler 10
#define BWhite 11
//Declare variables for functions
char user_input;
int x,u,v;
int y;
int state;
void setup() {
pinMode(stp, OUTPUT);
pinMode(dir, OUTPUT);
pinMode(MS1, OUTPUT);
pinMode(MS2, OUTPUT);
pinMode(MS3, OUTPUT);
pinMode(EN, OUTPUT);
pinMode(BRed,INPUT);
pinMode(BRedenabler,OUTPUT);
digitalWrite(BRedenabler, HIGH);
pinMode(BWhite,INPUT);
pinMode(BWhiteenabler,OUTPUT);
digitalWrite(BWhiteenabler, HIGH);
resetBEDPins();
Serial.begin(9600);
}
//Main loop
void loop() {
digitalWrite(EN, LOW);
u = digitalRead(BRed);
v = digitalRead(BWhite);
Serial.println(u);
digitalWrite(MS1, HIGH);
digitalWrite(MS2, HIGH);
digitalWrite(MS3, HIGH);
if (u==HIGH) {
StepForwardDefault();
}
else if (v==HIGH) {
ReverseStepDefault();
}
resetBEDPins();
}
//Reset Big Easy Driver pins to default states
void resetBEDPins()
{
digitalWrite(stp, LOW);
digitalWrite(dir, LOW);
digitalWrite(MS1, LOW);
digitalWrite(MS2, LOW);
digitalWrite(MS3, LOW);
digitalWrite(EN, HIGH);
}
//Default microstep mode function
void StepForwardDefault()
{
digitalWrite(dir, LOW); //Pull direction pin low to move "forward"
for(x= 1; x<2; x++) //Loop the forward stepping enough times for motion to be visible
{
digitalWrite(stp,HIGH); //Trigger one step forward
delay(1);
digitalWrite(stp,LOW); //Pull step pin low so it can be triggered again
delay(1);
}
}
//Reverse default microstep mode function
void ReverseStepDefault()
{
digitalWrite(dir, HIGH); //Pull direction pin high to move in "reverse"
for(x= 1; x<2; x++) //Loop the stepping enough times for motion to be visible
{
digitalWrite(stp,HIGH); //Trigger one step
delay(1);
digitalWrite(stp,LOW); //Pull step pin low so it can be triggered again
delay(1);
}
}
