Send Value of EEPROM to arduino

How I Can send the numbers or text saved in EEPROM memory of NEXTION TFT to arduino using the library for Arduino.


Can I use commands rept and wept ?. Any code for Arduino to make this.


Thanks



Arduino C++ comes already with many commands

Serial.print(), Serial.write(), Serial.read(), Serial.available() ...etc

Sprinkled in with some while, for and variable assignments


View the code of library, I create this code:


char buffer[4] = {0};

 uint32_t number;


cmd = "";

cmd = "rept 500,4";

sendCommand(cmd.c_str());

recvRetString(buffer[0],4);

recvRetCommandFinished(); 

number = buffer[0]+(buffer[1]<<8)+(buffer[2]<<16)+(buffer[3]<<24); 


but, this code not good. In the terminal I can see this message:


recvRetString[0,]

recvRetCommandFinished err


which is the problem?


I need help. Thanks.



recvRetCommandFinished is status - err means last command failed

recvRetString [0,4] is result of recvString - 0 means 0 bytes of 4 possible read


serial connected? underflow error?

Did you wait for response or read before ready?
