Hello

I'm takamitsu.

I want to connect raspberry pi with arduino to receve/send back information such as sensor deta/calculated input via usb port.

I think I should use serial write/read brocks,(In case of arduino , It's serial transmit/receive blocks ) but I have no idea about what prosidure should I take.

could you tell me about this?

Thanks.

Hi Takamitsu,

From what I understand, you are trying to utilize the Raspberry Pi's Serial communication for exchanging data between Pi and Arduino.

Similar to Arduino, we have Serial Read and Serial Write blocks.

I hope this information helps!

Thanks,

Prasanth

@Kiran Kumar

If you are using Windows, then open Device Manager, and look for USB ports. If you are fortunate, one of them will be explicitly labeled as being Arduino. If not, try the listed COM ports in turn.

In Simulink I am using serial receive block so which port in the block i should select for USB connection?
