請問我的arduino的serial monitor 為顯示出亂碼

請問一下,我是一枚arduino的萌新,因為要交學校的功課,左找右找的,在github 上找到了一個用來運行MLX90640(熱象探測)的arduino程式,並連接了那個機體,運行了起來。可是,我卻發現我的serial monitor出的是亂碼,我已經check了我的程式是Serial.begin(9600),也開了9600的bund,請問應當如何解決?謝謝。

p.s. 不知為何在copy and paste程式碼時,會多了一張相片在中間...
\OWO|||
檢查一下你的序列埠口的速率,檢查碼,停止位元的設定是否相同

試試看把右下角 new line 改成 nc & lr 看看

不行的話檢查板子吧

這個程式碼是for i2c使用的

試了,還是不行...或許要再看看其他方法吧!謝謝你

把 mlx90640To[x] 放到下面代碼轉成文字看看~

final String data=new String(mlx90640To[x], "US-ASCII");

請問一下,到底是要把
final String data=new String(mlx90640To[x], "US-ASCII");
造句放在那?
