Getting Started with ESP8266 NodeMCU V1.0 development board (Arduino IDE)

I wrote this blog, after struggling with the problem of the failure of the upload program from Arduino IDE to IOT board nodeMCU Amica Version 1.0 (on a board that is not installed NodeMCU x.x Lua) with the error message:

warning: espcomm_send_command: didn't receive command response
warning: espcomm_send_command(FLASH_DOWNLOAD_BEGIN) failed
error: espcomm_upload_mem failed

After searching for a reference to the web, finally got the solution.

Hopefully this article can help you if you have the same problem.

NodeMCU IOT is an open source platform that incorporate firmware which runs on top of ESP8266 Wi-Fi SoC.

Steps:

1. Plug Board NodeMCU on a breadboard

Figure 3. NodeMCU plugged in on breadboard

2. Install CP2102 (USB to Serial Converter) driver in accordance with the OS can be downloaded.

3. Record the port number,  for example COM4

3. Install Arduino IDE (Sketch) can be downloaded.

4. Install esp8266 boards manager

4.a. File -> References

4.b. Paste the following URL to the Additional Board Manager option

http://arduino.esp8266.com/stable/package_esp8266com_index.json

4.c. Tools -> Board ..., choose  Boards manager.

4.d. Scroll down, and choose esp8266 by ESP8266, and click on install.

Figure 6. Once the boards manager are installed

5. Set the right Board & Port

5.a. Tools -> Board ...,  chose NodeMCU 1.0 (ESP 12E module) from list.

5.b. Tools-> Port, select COM4 (according to step 3 above)

 Gambar 7. Parameter after setting

6. Plug a led on breadboard where the anode leg on pin D7, and cathoda on GND as shown below

Gambar  8. Plug a Led on pin D7 and GND

7. Create code as follow:

void setup() {
  pinMode(D7, OUTPUT);
}

void loop() {
  digitalWrite(D7, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);              // wait for a second
  digitalWrite(D7, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);              // wait for a second
}

8. Verify your code

9. Upload your code

Gambar 9. Upload succeed

If you do it right, then the LED will blink.

10. If failed

Trouble Shooting:

When upload you got this error message:

warning: espcomm_send_command: didn't receive command response
warning: espcomm_send_command(FLASH_DOWNLOAD_BEGIN) failed
error: espcomm_upload_mem failed

For more specified you can activate verbose mode (File-> Preference, and checkedon Show verbose output during (x) compilation (x) upload).

Solution:
The error can be caused by something prevent the board entered the programming/flash mode, to enabled the programming/flash mode pull up pin D3 (GPIO 0) to GND

Gambar 10. Pull pin D3 (GPIO 0) to GND

and try to upload again (verbose log when succeed).

Memulai dengan ESP8266 NodeMCU V1.0 development board (Arduino IDE)

Tulisan ini saya buat, setelah berkutat dengan masalah gagalnya upload program dari Arduino IDE ke board IoT nodeMCU Versi 1.0 Amica (pada board yang tidak terinstalasi NodeMCU x.x Lua)  dengan pesan Error:

warning: espcomm_send_command: didn't receive command response
warning: espcomm_send_command(FLASH_DOWNLOAD_BEGIN) failed
error: espcomm_upload_mem failed

Setelah mencari referensi ke Web, akhirnya mendapat solusi.

Semoga tulisan ini dapat membantu anda jika mengalami masalah yang sama.

NodeMCU adalah suatu open source IoT platform yang memasukan firmware yag mana berjalan diatas chip ESP8266 Wi-Fi SoC.

 Gambar 1. Board NodeMCU

 Gambar 2. Tampilan belakang Board NodeMCU

Langkah-langkah:

1. Tancapkan Board NodeMCU diatas breadboard

Gambar 3. NodeMCU yang ditancapkan diatas breadboard

2. Install driver CP2102 (USB to Serial Converter) sesuai dengan sistem operasi  yang dapat di download.

3. Catat nomor port hasil instalasi, misalnya COM4 

Gambar 4. Port setelah instalasi driver USB CP2102

3. Install Arduino IDE (Sketch) yang dapat di download

4. Install esp8266 boards manager

4.a. Pada menu File, pilih Preferences

4.b. Pada Additional Board Manager URLs isikan:

http://arduino.esp8266.com/stable/package_esp8266com_index.json

Gambar 5. Isian pada Preferences

4.c. Pada menu Tools, Board ..., pada sub menu pilih Boards manager.

4.d. Scroll kebawah, dan pilih esp8266 by ESP8266, dan install

 Gambar 6. Setelah boards manager diinstalasi

5. Pilih board & Port yang sesuai

5.a. Pada menu Tools, Board ...,  pada sub menu pilih NodeMCU 1.0 (ESP 12E module)

5.b. Pada menu Tools, Port, pilih COM4

 Gambar 7. Setting pada Tools

6.Buatlah rangkaian anda dimana kaki anoda pada pin D7, dan kaki cathoda pada GND

Gambar  8. Led pada pin D7 dan GND

7. Buat koding sebagai berikut:

void setup() {
  pinMode(D7, OUTPUT);
}

void loop() {
  digitalWrite(D7, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);              // wait for a second
  digitalWrite(D7, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);              // wait for a second
}

8. Lakukan verify

9. Lakukan upload

Gambar 9. Upload berhasil

Jika anda berhasil melakukan hal tersebut diatas, maka led akan blink.

10. Jika gagal

Trouble Shooting:

Pada saat upload muncul error:

warning: espcomm_send_command: didn't receive command response
warning: espcomm_send_command(FLASH_DOWNLOAD_BEGIN) failed
error: espcomm_upload_mem failed

Untuk mendapatkan verbose output yang lebih spesific, dapat disetting pada menu File, Preference, dan berikan tanda check pada Show verbose output during (x) compilation (x) upload.

Solusi:
Hal tersebut dapat terjadi karena board tidak berhasil masuk ke programming/flash mode, untuk memungkinkan programming/flash mode hubungkan pin D3 (GPIO 0) ke  GND

Gambar 10. Pull pin D3 (GPIO 0) ke GND

Dan coba Upload ulang (contoh verbose hasil upload yang berhasil).

Global variables use 32,368 bytes (39%) of dynamic memory, leaving 49,552 bytes for local variables. Maximum is 81,920 bytes.
