1.  Connect Spyder’s pin 2 to GPIO 1 on pcDuino, spyder’s pin 3 to GPIO 0 on pcDuino, pin 10 to GND of pcDuino.

2.Connect the powerline interfaces of these two spyder and power them up( DC5-12V).

3.Power up pcDuino.[/vc_column_text][/vc_tab][vc_tab title=”Parts List” tab_id=”1388375452-2-80″][vc_column_text]pcduino V2  x 1

The code in above structure can achieve interacting AT command between pcDuino and Spyder, but this time we use UART of pcDuino instead of USB port. You can cancel the comments to see how it goes if you want, but do not forget to add these comments to the original code without comments.

Code for pcDuino Lite wifi:

#include <core.h>

/*********************

static unsigned char i = 0;
void setup(){
Serial.begin(9600);
}

void loop(){
if(i == 0){
Serial.print(“+++”);
printf(“+++ have send!\n”);
}
else if (i == 1){
Serial.print(“ATSN”);
Serial.print(‘\n’);
printf(“ATSN have send!\n”);
}
else if (i == 2){
Serial.println(“ATEX”);
printf(“ATEX have send!\n”);
}
while(Serial.available() > 0){
printf(“%c”,Serial.read());
}
i++;
delay(3000);
}
************************/
void setup(){
Serial.begin(9600);
}

void loop(){
Serial.println(“Lite Wifi:520linksprite!”);
delay(1000);
while(Serial.available() > 0){
char c = Serial.read();
printf(“%c”,c);
}
}

Code for pcDuino V2:

#include <core.h>

/*********************

}
else if (i == 2){
Serial.println(“ATEX”);
printf(“ATEX have send!\n”);
}
while(Serial.available() > 0){
printf(“%c”,Serial.read());
}
i++;
delay(3000);
}
************************/
void setup(){
