Hi folks,
I have a problem with my project. I hope you could help me with it. My knowledge in electronic is rather limited. Full details of the problems are described below.
My problem is
_ I have linear stage that can be connected to PC via USB ports and controlled via an open source software based on Microsoft.Net languages. I have sensors that can be triggered via TTL level signals (Vmax = 5V).
_ I want the sensors to start measuring at the same time as when the stage starts moving or with a fixed delay (to avoid the acceleration).
My thought for this problem is
_ I will connect the stage and the Arduino Due (Native Port) to USB ports of the PC.
_ With the control software, I can initialize the communication between the PC and the stage and the Arduino.
_ Commands to move the stage will be sent to both ports.
_ When the Arduino receives signals from the PC via the USB port (probably Rx line), it will switch an I/O pin to "high" and this signal will be sent to the sensors for triggering.
May I know how to make the Arduino respond when the data is transmitted via USB port?
Thank you very much for your help.
Cheers,
QTL
