要檢查我的cc3000 Wifi Shield是否有效,請下載Adafruit CC3000 Library並在庫中運行該示例,該程序爲「buildtest」。Arduino CC3000 Wifi Shield無法在cc3000程序庫中運行「buildtest」
這裏是Adafruit和圖書館的鏈接。
https://learn.adafruit.com/adafruit-shield-compatibility/cc3000-wifi-shield
https://github.com/adafruit/Adafruit_CC3000_Library
但是當我運行 'buildtest',唯一的事情,我可以在串口監視器看到的是腐敗(或亂碼)消息。
以下爲在庫 'buildtest' 的代碼。

對不起,我知道這是很長的代碼,但我不明白爲什麼我得到了損壞的消息。
我不認爲這個問題與WIFI(#define WLAN SSID或#define WLAN PASS)的設置有關。
因爲......如果你看一下「無效設置」功能,你可以看到
Serial.println(F("Hello, CC3000!\n"));
所以我應該看到這條消息(你好CC3000)不管是什麼。
即使我設置了我的WLAN SSID和WLAN PASS,也會出現相同的損壞消息。
我無法檢查我的cc3000是否可以正常工作,因爲這種損壞的消息。
我該如何解決這個問題?
確認串行監視器運行速度爲115,200 bps,聽起來相當高。 – unwind
