Hi,

I work the wifi module and lcd display. But not at the same time. Please help.

#include

RF24 radio(9,10);

LCD5110 myGLCD(4, 3, 2, 0, 1);

extern uint8_t SmallFont[];
extern uint8_t MediumNumbers[];
extern uint8_t BigNumbers[];

//boolean start = true; 
float Voltage = 0;
float Current = 0;
char result[8];
char MyTag[]="EOS-SEM";
char sendingMessage[16];

void setup(void) {

myGLCD.InitLCD();

radio.begin();
radio.setPALevel(RF24_PA_MAX);
radio.setChannel(0x70);
radio.openWritingPipe(0xF5F5F5F5E1LL);
radio.enableDynamicPayloads();
radio.powerUp();
Serial.begin(9600);
delay(1000);
Serial.println("start ");
radio.stopListening();//yeni ekledim.. 



}

void loop(void){




Serial.print("Olcum Yapiliyor = ");
Voltage = 0;
Current = 0;
for(int i = 0; i<1000; i++) {
 Voltage = (Voltage + (.0049 * analogRead(A0))); // (5 V / 1024 = 0.0049) which converter Measured analog input voltage to 5 V Range
delay(1);
}

Voltage = Voltage /1000;
Current = (Voltage - 2.5)/ 0.066; // Sensed voltage is converter to current
//Voltage = Voltage - 2.5;
dtostrf(Current, 6, 2, result);
CreateSendingMessage(MyTag,result);
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):

Serial.print("Current = ");
Serial.println(Current,2); 
//Serial.print("Voltage = ");
//Serial.println(Voltage,2);
Serial.print("Sending message=>");
Serial.println(sendingMessage);
//if(start == true){ 
//const char text[] = "sabri" ;
//radio.write(&text, sizeof(text));
radio.write(&sendingMessage, sizeof(sendingMessage));
delay(200);//veriyi gonderdik eskiden 1 sn idi.

myGLCD.clrScr();
myGLCD.print("Hasan Ali ", LEFT, 0);
delay (5000);


}
void CreateSendingMessage(char* tag, char* data)
{
for(int k=0;k<7;k++)
 sendingMessage[k] = *(tag+k);
sendingMessage[7]=':';
for(int k=8;k<16;k++)
 sendingMessage[k] = *(data+k-8);
}

Have a nice day.

Why have you deleted the library names ?
You have not formatted the code very nicely (use Tools > Autoformat in the IDE) and have left html characters eg
in the code.

You appear to be using pins 0 and 1 for the display and this may cause a conflict with the serial console.

You should post a wiring diagram and the code of the receiver and state whether the radio works if you comment out the code which handles the display.

I'm not sure why you have 3 #includes with no filenames. But it looks like you may be using pins 0 and 1 for the LCD. Then you are also using Serial...which uses pins 0 and 1.
