Servo_HelloWorld Example for WIZwiki-W7500
Fork of
Servo_HelloWorld
by 
Simon Ford
Prerequisite
This example is for servo motor test using digital I/O(PWM).
To implement this function, you need a Platform board, network Interface board.
- WIZwiki-W7500 from WIZnet (Platform board and Ethernet I/F board)
Hardware Configuration
WIZwiki-W7500 Pin map
Servo Motor(HS-5585MH)
Wiring Table
| HS-5585 | W7500 |
| VCC | 5V |
| GND | GND |
| SIGNAL | D14 |
Software
Init GPIO
Servo myservo(D14);
Set data to Servo
for(float p=0; p<1.0; p += 0.1) {
myservo = p;
wait(0.2);
}
Caution
When wiring, be careful (GND, VCC)
