為配合上面的690A signal reverser的測試，使用 LGT8F328P 在 Arduino下編寫的一個簡單測試程序：
/*
Servo Signal Generator For Test Purpose
*/
# define ServoOut 13
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin as Servo output.
pinMode(ServoOut, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
///*
digitalWrite(ServoOut, HIGH); // turn the ServoOut on (HIGH is the voltage level)
delayMicroseconds(1500 * 1.33); // wait for a second
digitalWrite(ServoOut, LOW); // turn the ServoOut off by making the voltage LOW
delay(15); // wait for a second
//*/
/*
for (int i = 8; i < 20; i++) {
for (int j = 750; j < 2250; j=j+10) {
digitalWrite(ServoOut, HIGH); // turn the ServoOut on (HIGH is the voltage level)
delayMicroseconds(j * 1.33); // wait for a second
digitalWrite(ServoOut, LOW); // turn the ServoOut off by making the voltage LOW
delay(i); // wait for a second
}
}
/*
digitalWrite(ServoOut, HIGH); // turn the ServoOut on (HIGH is the voltage level)
delayMicroseconds(750 * 1.33); // wait for a second
digitalWrite(ServoOut, LOW); // turn the ServoOut off by making the voltage LOW
delayMicroseconds(1500*1.33); // wait for a second
*/
/*
for (int j = 400; j < 1120; j++) {
digitalWrite(ServoOut, HIGH); // turn the ServoOut on (HIGH is the voltage level)
delayMicroseconds(j * 1.33); // wait for a second
digitalWrite(ServoOut, LOW); // turn the ServoOut off by making the voltage LOW
delayMicroseconds(2000*1.33); // wait for a second
}
