# upy-esp8266-gpiod

這個專案啟發來自於 **MicroPython** http://docs.micropython.org/en/latest/esp8266/tutorial/intro.html#intro

以及它的函式庫 https://github.com/micropython/micropython-lib/tree/master/umqtt.robust

## 我是在ubuntu18的桌上型電腦做這些實驗,

### 首先要確定你的"USB轉TTL線"運作是否正常,刪除flash 

![uart-wiring](/images/usb_ttl_esp8266.jpg)

```

esptool.py --port /dev/ttyUSB0 erase_flash

```

### 下載最新的韌體,

```

wget http://micropython.org/resources/firmware/esp8266-20190125-v1.10.bin

```

### 燒錄韌體（又稱flashing)

```

sudo esptool.py --port /dev/ttyUSB0 --baud 460800 write_flash --flash_size=detect 0 esp8266-20190125-v1.10.bin

```

### 使用picocom連線到micropython操作系統

```

sudo picocom /dev/ttyUSB0 -b115200

```

### 啟動wifi station mode(以下是在micropython內）

```

import network

sta=network.WLAN(network.STA_IF)

sta.active(True)

sta.connect('ESSID','WIFI_PASSWORD')

sta.ifconfig()

```

假如連線正常時,你會看到它（esp8266)的ip,gateway等資料

### 啟用WebRepl,就是用wifi與瀏覽器直接連上esp8266(在micropython內）

```

import webrepl_setup

```

它會要求你輸入密碼,很重要,仔細做

### 用你的電腦瀏覽器連上esp8266

```

http://micropython.org/webrepl/?

```

把 ws://192.168.4.1:8266/ 換成上面拿到esp的ip地址 例如 ws://10.40.80.2:8266/

然後按下connect

這時候輸入密碼

### 上傳額外的程式

![uploader](/images/file_uploader.png)

點 **選擇檔案** , 選好以後再點 **send to device**

只要改main.py以下這幾行，並且上傳就行了，但是似乎有些小bug

```

#每個人的服務器地址都不同哦

SERVER='m9999.cloudmqtt.com'

#這個連接埠是未加密

PORT=1883

#這是帳號

USR='MQTT_USER'

#這是密碼

PWD='MQTT_PASSWD'

#keep-alive=3 minutes

KEEPALV=180

#這是client id

UUID='UUID-1234-5678'

```

### 在micropython按 **ctrl+D** 重啟
