Victor 888 by Arduino Uno R3
This is not an FRC or FIRST related project.
I'm using a Victor 888 and an Arduino Uno R3 to power a BAG motor through PWM. I'm using a FIRST battery. I found this sample code on Arduino's forums: #include <SoftwareServo.h> SoftwareServo servo1; SoftwareServo servo2; void setup() { pinMode(9,OUTPUT); servo1.attach(2); servo1.setMaximumPulse(2200); servo2.attach(4); servo2.setMaximumPulse(2200); Serial.begin(9600); Serial.print("Ready"); } void loop() { static int value = 0; static char CurrentServo = 0; if ( Serial.available()) { char ch = Serial.read(); switch(ch) { case 'A': servo1.attach(2); CurrentServo='A'; digitalWrite(13,LOW); break; case 'B': servo2.attach(4); CurrentServo='B'; digitalWrite(13,HIGH); break; case '0' ... '9': value=(ch-'0')*20; if (CurrentServo=='A') { servo1.write(value); } else if (CurrentServo=='B') { servo2.write(value); } break; } } SoftwareServo::refresh(); } and this from another Chief Delphi post: //Simple VEX Pro Victor 888 Driver unsigned short pin = 9; signed int dutyCycle = 0; unsigned int highus = 1500; unsigned int lowus = 1000; void setup() { pinMode(pin, OUTPUT); digitalWrite(pin, LOW); Serial.begin(9600); } void loop() { digitalWrite(pin, HIGH); delayMicroseconds(highus); digitalWrite(pin, LOW); delayMicroseconds(lowus); if (Serial.available() > 0) { highus = 5*Serial.parseInt() + 1500; lowus = 1000; Serial.print("DS: "+dutyCycle); } } I have a VEX Pro VersaPlanetary 10:1 Gearbox and I need the motor to run at 600 RPM, so I can get 60 RPM from the gearbox. I've also looked through Arduino's servo library. Any advice? |
