關於 Arduino Web Editor 無法上傳問題 (not in sync)

上週買的 ESP32-CAM 開發板經我上網研究, 發現目前還沒有 MicroPython 的範例程式碼釋出, 因此得先用 Arduino IDE 去開發. 但我這台 Acer Swift5 今年初買來至今尚未做過 Arduino 實驗, 故需下載 Arduino IDE 才行. 但到官網卻赫然發現 Arduino 居然已經有雲端線上版本, 好處是不需下載永遠是最新版, 那就先註冊個帳號吧!

# Sign up an Arduino account

使用 email 註冊後收信, 按信中的確認連結完成註冊即可 :

接著在 Aduino 官網首頁右上角按 Sign in 登入帳號後, 點選 Software/Online Tools 再按左上角的 Arduino Web Editor  :

這時會出現下載 Arduino plugin 提示訊息, 點選超連結下載 plugin 後執行 Arduino create agent :

這樣就可以將 Arduino 板子連接 USB 埠開始使用了. 先選擇板子與 COM 埠, 我使用的是 Nano 與 COM7 :

然後從左邊 Example/Basics 選取 Blinks 範例, 再按向右鍵 (Upload) 上傳程式 :

但是, 過了很久還是一直顯示 Busy, 最後底下的訊息視窗顯示如下 "not in sync" 的錯誤訊息 :

avrdude done. Thank you.

查詢網路有人說電腦重開機即可, 但我試過那不管用. 我用下載下來的 Arduino IDE 上傳就可以順利上傳.

後來在 Stack overflow 下面這篇的第 13 個回應找到解答, 原來我這塊 Nano 的 MPU 比較舊, 要選 "Atmega328P (Old Bootloader)" :

# “avrdude: stk500_getsync(): not in sync: resp=0x00,” aka Some Dude Named Avr Won't Let Me Upload My Program

"Change Tools->Processor->Atmega 328P to Atmega 328P (Old Bootloader). Remind that the Processor option is only available when you select some specific Boards at Tools>Board.
This worked for my Arduino Nano with CH340, using Arduino IDE 1.8.5 under Linux Ubuntu 17.10. Besides, this will probably happen if you use IDE 1.8.9 or newer and you get an old or cloned Nano."

我更改板子為 Atmega328P (Old Bootloader) 後就解決上傳問題了 :

可見使用較低的 baud rate 傳送就能 sync 而上傳成功了.
