Scott Jeong
Prerequisite
This example is for PIR test using digital I/O.
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
PIR Sensor(HC-501SR) Pin map
Wiring Table
| HC-501SR | W7500 |
| VCC | 5V |
| GND | GND |
| SIGNAL | D8 or PC_7 |
Software
Init GPIO
DigitalOut myled(LED1); // Alert LED DigitalIn PIR(PC_7); // PIR Signal //D8
Get data from PIR
int PIR_sensor; // declare variable for PIR input data
while(1) {
PIR_sensor = PIR; // Check input signal from PIR pin
pc.printf("PIR Value : %d\r\n",PIR_sensor);
myled =! PIR_sensor; // PIR(HIGH) == LED On // PIR(LOW) == LED Off
wait(0.1f);
}
Caution
When wiring, be careful (GND, VCC)
