我使用从串行端口接收一些数据信号Serial Receive块（当然还有串行配置块）。我用它来移动视频中的标记。它在模拟期间工作，但是当我使用生成 .exe 文件时Simulink Coder执行期间标记不会移动。看起来它没有从串行接收数据。
*EDIT:*原始数据是int16但“来源”是建立在Arduino Mega2560 using Target Support Package所以使用Arduino serial send阻止它生成源USB COM port波特率为9600。因为Arduino serial block只想要uint8我用了一个byte pack block before Arduino Serial block。参数为byte pack block are:
1)Input port data types = {'int16'}
2)Byte Alignment = 2在收到我使用的模型中Serial Receive阻止来自instrument control toolbox with:
(Serial Configuration Block:)
Baud Rate = 9600;
Data Bits = 8;
Stop Bits = 1;
Byte Order = LittleEndian;
Flow Control = none;
Time Out = 10;
Header = none;
Terminator = none;
Data size = [2 1];
Data Type = uint8;
Enable blocking mode = flag;
Action when data is unavailable = output last received value;
Block sample time = (same sample time setted in the model built on Arduino)
I have connected this Serial Receive Block to a Byte Unpack block with:
Output dimensions = {[1]};
Output Port Data types = {'int16'} (data type of original signal)
建议？
