Hello everyone, i have a question about (Arduino UNO)+(Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface - PCA9685) and my system is Windows and OSX.
this's my program...
#include <Wire.h>
#include <Adafruit_PWMServoDriver.h>
Adafruit_PWMServoDriver pwm = Adafruit_PWMServoDriver();
#define SERVOMIN 150
#define SERVOMAX 600
uint8_t servonum = 0;
void setup() {
Serial.begin(9600);
Serial.println("16 channel Servo test!");
pwm.begin();
pwm.setPWMFreq(60);
}
void setServoPulse(uint8_t n, double pulse) {
double pulselength;
pulselength = 1000000;
pulselength /= 60;
Serial.print(pulselength); Serial.println(" us per period");
pulselength /= 4096;
Serial.print(pulselength); Serial.println(" us per bit");
pulse *= 1000;
pulse /= pulselength;
Serial.println(pulse);
pwm.setPWM(n, 0, pulse);
}
void loop() {
for (uint16_t pulselen = SERVOMIN; pulselen < SERVOMAX; pulselen++) {
pwm.setPWM(0, 0, pulselen);
pwm.setPWM(1, 0, pulselen);
pwm.setPWM(2, 0, pulselen);
pwm.setPWM(3, 0, pulselen);
pwm.setPWM(4, 0, pulselen);
pwm.setPWM(5, 0, pulselen);
pwm.setPWM(6, 0, pulselen);
pwm.setPWM(7, 0, pulselen);
pwm.setPWM(8, 0, pulselen);
pwm.setPWM(9, 0, pulselen);
pwm.setPWM(10, 0, pulselen);
pwm.setPWM(11, 0, pulselen);
pwm.setPWM(12, 0, pulselen);
pwm.setPWM(13, 0, pulselen);
pwm.setPWM(14, 0, pulselen);
pwm.setPWM(15, 0, pulselen);
}
delay(500);
for (uint16_t pulselen = SERVOMAX; pulselen > SERVOMIN; pulselen--) {
pwm.setPWM(0, 0, pulselen);
pwm.setPWM(1, 0, pulselen);
pwm.setPWM(2, 0, pulselen);
pwm.setPWM(3, 0, pulselen);
pwm.setPWM(4, 0, pulselen);
pwm.setPWM(5, 0, pulselen);
pwm.setPWM(6, 0, pulselen);
pwm.setPWM(7, 0, pulselen);
pwm.setPWM(8, 0, pulselen);
pwm.setPWM(9, 0, pulselen);
pwm.setPWM(10, 0, pulselen);
pwm.setPWM(11, 0, pulselen);
pwm.setPWM(12, 0, pulselen);
pwm.setPWM(13, 0, pulselen);
pwm.setPWM(15, 0, pulselen);
}
delay(500);
}
I check my tool>board & port & programmer, and IC bootloader it's working. i can use "upload" and servo motor it's working, just can't "upload using programmer",but the other program can use "upload using programmer"...
this's my error messages.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
so i want know why? if any answer to help me, please tell me, thank you so much.(Q_Q)
