I have cisco e900 router, with dd-wrt firmware, i connect it to arduino uno-r3 + LCD 16*2 to show-up the status and some data from that router, anyway i am using TX-RX port in both sides my problem is: there is no data!! arduino LCD just showing that > "dd-wrt - powerd cisco e900"
is there any mistake i make in my code !! this is my code on my arduino
#include <Wire.h>
#include <LiquidCrystal.h>
LiquidCrystal lcd(7, 8, 9, 10, 11, 12);
int led1 = 8;
float raw;
byte bl[8] = {
B00000,
B00000,
B00000,
B00000,
B00000,
B00000,
B00000,
};
void setup(){
pinMode(led1, OUTPUT);
lcd.begin(16, 2);
Serial.begin(9600);
lcd.createChar(1, bl);
lcd.createChar(2, bl);
lcd.createChar(3, bl);
lcd.createChar(4, bl);
lcd.setCursor(0,0);
lcd.print("dd-wrt - powered");
lcd.setCursor(0,1);
lcd.print("cisco e900");
}
void loop()
{
int charcount;
boolean secondline;
if (Serial.available()) {
delay(200);
lcd.clear();
charcount = 0;
secondline = false;
while (Serial.available() > 0) {
if (charcount > 15 && secondline == false ) {
lcd.setCursor(0,1);
secondline = true;
}
char inChar = (char)Serial.read();
if (inChar != '\0') {
lcd.write(inChar);
}
if (inChar == '\3') {
digitalWrite(led1, HIGH);
}
if (inChar == '\4'){
digitalWrite(led1, LOW);
}
charcount++;
}
}
}
and this command on my router cisco e900
