I'm having a problem sending the same information to two different and independent softwares in my computer. In this project, I have a pressure sensor which is connected to an analog pin in my arduino UNO and i want the data to be sent to MyOpenLab for monitoring and to excel for recording using the PLX-DAQ. For the connection to MyOpenLab I'm using the Firmata example, although I think it's irrelevant for this problem. It works fine if I only use one of the softwares, but when I try to connect the two, it doesn't work. Is there a way for me to use the same COM port for both softwares?
Thank you in advance.
