SyRen/Sabertooth Packet Serial Library for Arduino
Control your SyRen or Sabertooth with reliable Packet Serial.

Sweeps from full reverse to full forward and then from full forward to full reverse.

#include <Sabertooth.h>
// If you've set up your Sabertooth on a different address, of course change
// that here. For how to configure address, etc. see the DIP Switch Wizard for
// Sabertooth - http://www.dimensionengineering.com/datasheets/SabertoothDIPWizard/start.htm
// SyRen - http://www.dimensionengineering.com/datasheets/SyrenDIPWizard/start.htm
// Be sure to select Packetized Serial Mode for use with this library.
//
// On that note, you can use this library for SyRen just as easily.
// The diff-drive commands (drive, turn) do not work on a SyRen, of course, but it will respond correctly
// if you command motor 1 to do something (ST.motor(1, ...)), just like a Sabertooth.
//
// In this sample, hardware serial TX connects to S1.
// See the SoftwareSerial example in 3.Advanced for how to use other pins.
void setup()
{
SabertoothTXPinSerial.begin(9600); // 9600 is the default baud rate for Sabertooth packet serial.
ST.autobaud(); // Send the autobaud command to the Sabertooth controller(s).
// NOTE: *Not all* Sabertooth controllers need this command.
// It doesn't hurt anything, but V2 controllers use an
// EEPROM setting (changeable with the function setBaudRate) to set
// the baud rate instead of detecting with autobaud.
//
// If you have a 2x12, 2x25 V2, 2x60 or SyRen 50, you can remove
// the autobaud line and save yourself two seconds of startup delay.
}
void loop()
{
int power;
// Ramp motor 1 from -127 to 127 (full reverse to full forward),
// waiting 20 ms (1/50th of a second) per value.
for (power = -127; power <= 127; power ++)
{
ST.motor(1, power);
delay(20);
}
// Now go back the way we came.
for (power = 127; power >= -127; power --)
{
ST.motor(1, power); // Tip for SyRen users: Typing ST.motor(power) does the same thing as ST.motor(1, power).
delay(20); // Since SyRen doesn't have a motor 2, this alternative can save you typing.
