How To Upload Amica Nodemcu

Tulisan ini saya buat, setelah berkutat dengan masalah gagalnya upload plan dari Arduino IDE ke board IoT nodeMCU Versi ane.0 Amica (pada board yang tidak terinstalasi NodeMCU x.ten Lua ) dengan pesan Error:

warning: espcomm_send_command: didn't receive command response
alert: 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 fleck ESP8266 Wi-Fi SoC.

Gambar 2. Tampilan belakang Board NodeMCU

Langkah-langkah:

1. Tancapkan Board NodeMCU diatas breadboard

Gambar three. 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 four. Port setelah instalasi driver USB CP2102

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

4. Install esp8266 boards director

4.a. Pada menu File, pilih Preferences

4.b. Pada Additional Lath Director URLs isikan:

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

Gambar 5. Isian pada Preferences

4.c. Pada carte du jour Tools, Board ..., pada sub menu pilih Boards managing director.

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

five. Pilih board & Port yang sesuai

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

5.b. Pada bill of fare Tools, Port, pilih COM4

Gambar 7. Setting pada Tools

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

Gambar viii. 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
filibuster(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 control response
alarm: espcomm_send_command(FLASH_DOWNLOAD_BEGIN) failed
mistake: espcomm_upload_mem failed

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

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

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

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