Use to WIZwiki-W7500, Sensing to PIR motion sensor module(HC-SR501)
Dependencies: mbed
Fork of PIR_Motion_Sensor_WIZwiki-W7500 by
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)

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)
