errors w/ FULL2WIRE ? about easy_driver HOT 17 CLOSED

from easy_driver.

ok thanks that helped although now i noticed that it does not follows some of the serial calls such as "r" for reverse or 1 by it's sign, any ideas why? it will accept s & f as well as 1,2 & 3 but that r

void loop()
{
char c;
if (Serial.available()) {
c = Serial.read();
if (c == 'f') { // forward
sign = 1;
}
if (c == 'r') { // reverse
sign = -1;
}
if (c == 's') { // stop
sign = 0;
}
if (c == '1') { // super slow
spd = 300;
}
if (c == '2') { // medium
spd = 500;
}
if (c == '3') { // fast
spd = 1000;
}
stepper.setSpeed(sign * spd);
}
stepper.runSpeed();
}

every command it's accepted BUT reverse

yes i start that sketch at S because i do not want it just running at start right, then ill have to open the serial window to input the command i want F, S or the non working one R as i already have it set at 3 which is 1000 but R just gets ignore, ill even hit S the R and it will spin in the same dir as if i would have hit F instead so it looks like F&R are given out the same val of 1 and never -1 respectfully. but thanks for having a look at it.

im not sure but i think the issue might be here

boolean AccelStepper::runSpeed()
{
unsigned long time = millis();

if (time > _lastStepTime + _stepInterval)
{

if (_speed > 0)
{
// Clockwise
_currentPos += 1;
}
else if (_speed < 0)
{
// Anticlockwise
_currentPos -= 1;
}
step(_currentPos & 0x3); // Bottom 2 bits (same as mod 4, but works with + and - numbers)

_lastStepTime = time;
return true;
}
else
return false;
}
or it might be here or both

void AccelStepper::step4(uint8_t step)
{
switch (step)
{
case 0: // 1010
digitalWrite(_pin1, HIGH);
digitalWrite(_pin2, LOW);
digitalWrite(_pin3, HIGH);
digitalWrite(_pin4, LOW);
break;

case 1: // 0110
digitalWrite(_pin1, LOW);
digitalWrite(_pin2, HIGH);
digitalWrite(_pin3, HIGH);
digitalWrite(_pin4, LOW);
break;

case 2: //0101
digitalWrite(_pin1, LOW);
digitalWrite(_pin2, HIGH);
digitalWrite(_pin3, LOW);
digitalWrite(_pin4, HIGH);
break;

case 3: //1001
digitalWrite(_pin1, HIGH);
digitalWrite(_pin2, LOW);
digitalWrite(_pin3, LOW);
digitalWrite(_pin4, HIGH);
break;
}
}

No it does not spin in reverse

Well good thing i buy everything in bulk, i did pull out 2 additional sets "drivers & Steppers" and the issue is in the first Driver i was using to run test on, one of the pins on the ic must of shortened although not visible nor smells but i confirmed this by using that same stepper i been using on a new driver and all your commands worked flawlessly, thanks for your efforts and the update.

from easy_driver.

ok i think im on to something new but im not sure maybe is just my code this time as everything im using it's new, please look at my code and tell me if you see something wrong, because i just hooked the full system connection (HW & SW) and im lacking individual control "meaning both motors are running in the same direction although i only called one" and to top it off i have to enter double digits such as aa or dd / rr or ff to get the command to register.

note i just have 2 simple functions being called in loop in which serial is going to get one of those 2 commands respectfully to run the motors in their respected polarity using char c or e.

no i understand but what if this is a issue where the libraries aren't working with multiple steppers? but if you insist whats your email Brian?
