How to programming the esp8266 module with FTDI

To program the ESP8266 module with an FTDI, you will need to follow these steps:

Download and install the Arduino IDE.
Open the Arduino IDE and go to the “File” menu, then select “Preferences.”
In the “Additional Boards Manager URLs” field, enter the URL for the ESP8266 board manager: “http://arduino.esp8266.com/stable/package_esp8266com_index.json“

Parts Required:

ESP8266-01
FT232RL FT232 USB ZU TTL 5 V 3,3 V
LEDs(2)
Wire to connect it all together

programming esp8266 — Wiring the ESP8266-01 only For Programming.

Fix error in Arduino IDE:

warning:espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed

To fix the error put a jumper wire between Ground and Io0 (IO Zero) to put the Esp8266-01 in the Programming mode

ARDUINO IDE CONFIGURATION:

select the port shown on your side, in my case I got Com6.

Arduino test Code:

/* * Hisham Marzouk * https://www.Officialhrm.com * The server will set a GPIO pin depending on the request * http://Esp8266_server_ip/gpio/0 will set the Blue LED low,* http://Esp8266_server_ip/gpio/1 will set the Blue LED high, * http://Esp8266_server_ip/gpio1/2 will set the Green LED low, * http://Esp8266_server_ip/gpio1/3 will set the Green LED high, * server_ip is the IP address of the ESP8266 module, will be * printed to Serial when the module is connected. */

#include <ESP8266WiFi.h>

const char* ssid = “officialhrm”; // write your SSID
const char* password = “123456789”; // write your Password

// Create an instance of the server
// specify the port to listen on as an argument
WiFiServer server(80);

void setup() {
Serial.begin(115200);
delay(10);

// prepare GPIO2
pinMode(2, OUTPUT);
digitalWrite(2, 0);

// prepare GPIO0
pinMode(0, OUTPUT);
digitalWrite(0, 0);

// Connect to WiFi network
Serial.println();
Serial.println();
Serial.print(“Connecting to “);
Serial.println(ssid);

WiFi.mode(WIFI_STA);
WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(“.”);
}
Serial.println(“”);
Serial.println(“WiFi connected”);

// Start the server
server.begin();
Serial.println(“Server started”);

// Print the IP address
Serial.println(WiFi.localIP());
}

void loop() {
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}

// Wait until the client sends some data
Serial.println(“new client”);
while(!client.available()){
delay(2);
}

// Read the first line of the request
String req = client.readStringUntil(‘\r’);
Serial.println(req);
client.flush();

// Match the request
int val;
int val1;

if (req.indexOf(“/gpio/0”) != –1){
val = 0;
digitalWrite(2, val);}
else if (req.indexOf(“/gpio/1”) != –1){
val = 1;
digitalWrite(2, val);}
else if (req.indexOf(“/gpio1/2”) != –1){
val1 = 0;
digitalWrite(0, val1);}
else if (req.indexOf(“/gpio1/3”) != –1){
val1 = 1;
digitalWrite(0, val1);}
else {
Serial.println(“invalid request”);
client.stop();
return;
}
client.flush();
}

After Uploading:

Remove the Io0 (IO Zero) from Ground
In the Arduino IDE Open the Serial Monitor Window by Pressing (Ctrl+Shift+M)
remove the VCC(3.3V) from the ESP8266 module and reconnect it to get the Server Ip Address

in my case, I got 192.168.0.4 as Esp8266_server_ip

Now connect Io0 and Io2 to LEDs Open this links below in your Explorer (Chrome).

http://Esp8266_server_ip/gpio/0 will set the IO0 low,http://Esp8266_server_ip/gpio/1 will set the IO0 high, http://Esp8266_server_ip/gpio1/2 will set the IO2 low, http://Esp8266_server_ip/gpio1/3 will set the IO2 high,

I am getting an error at the beginning where the ssid and password are declared. I have not done much C coding so I am stuck! The error is:

I am having problems programming the ESP-01 using your instructions. Can you tell me what version of the Generic ESP8266 board you had installed when you did this article. I don’t know if this would cause the problem I am having, as it says that the serial port dose not exist or the board is not connected.
I have checked the connections and they are correct. What do the LED’s on the esp01 indicate?
Hope you can help?
