用matlab写CAN上位机时,CAN接收程序是如何写

在MATLAB中,可以使用CAN工具箱来编写CAN接收程序。以下是一个简单的CAN接收程序示例,可以作为参考:
```matlab
% 创建一个CAN通道
canChannel = canChannel('Vector', 'CANcaseXL 1', 1);
% 设置CAN通道的波特率
set(canChannel, 'BaudRate', 500000);
% 创建一个CAN消息过滤器
canFilter = canFilter('ID', 0x100, 'Mask', 0x7FF);
% 启用CAN通道和CAN消息过滤器
start(canChannel);
start(canFilter);
% 循环接收CAN消息
while true
% 从CAN通道中读取CAN消息
canMessage = receive(canChannel, 1);
% 如果收到了CAN消息,则处理消息
if ~isempty(canMessage)
% 显示CAN消息数据
disp(canMessage.Data);
end
end
% 停止CAN通道和CAN消息过滤器
stop(canChannel);
stop(canFilter);
```
在这个示例中,首先创建一个CAN通道和一个CAN消息过滤器。然后设置CAN通道的波特率,并启用CAN通道和CAN消息过滤器。接下来,使用一个无限循环来持续接收CAN消息。当接收到CAN消息时,显示CAN消息数据。最后,在程序结束时停止CAN通道和CAN消息过滤器。
