Serial Port Com1 Not Found Arduino
asked Nov 26 '15 at 19:53 M. Shaaban 614 To be able to help you it would really help to know your development environment (what OS are you working on, how are you connecting to the serial port, etc.). The message suggests that another process using the serial port, it could be as simple as need to close and reopen your terminal emulator. –dlu Nov 26 '15 at 20:01 Im using windows 8.1, and im connecting to the serial port via usb. –M. Shaaban Nov 26 '15 at 20:04 How are you connecting to the serial port (what software are you using to received the serial data)? I don't do much with Windows, but I think the problem that you're having is that your terminal emulator is expecting to see the data on your COM1 port but you're actually transmitting the data over USB and a virtual serial port. The serial monitor in the Arduino IDE picks up the serial port from the setting in the menu Tools > Port (which is also used for your upload), but other programs will need it to be explicitly set. –dlu Nov 26 '15 at 20:09 the software is built in the ar

After getting the necessary cables, I decided to upload an example to the chip. Instead of seeing that Blink, I received an error like processing.app.SerialException: Serial port 'COM1' not found. Did you select the right one from the Tools > Serial Port menu? Yes, I tried that. But even Serial Port Monitor doesn't seem opening. Then again, I get some exception that isn't serial port com1 worth mentioning. After I found out that my Serial COM ports don't work (via Portmon.exe), and figuring out that I may even don't have any (there is no COM port in Device Manager), I also tried to download a driver for COM port, but it has also failed. Some say that it's because of my Acer Aspire 5742's motherboard. Some say that the reason is Windows 7. Long story short, I'd really appreciate if someone can help me with my COM port problem and mend my broken dreams. serial-port arduino share|improve this question edited Jan 29 '15 at 13:49 user2428118 5,23712751 asked Nov 5 '12 at 0:10 3yanlis1bos 45621033 add a comment| 6 Answers 6 active oldest votes up vote 15 down vote accepted Installing Drivers for Arduino in Windows 8 / 7. ( I tried it for Uno r3, but i believe it will work for all Arduino Boards ) Plugin your Arduino Board Go to Control Panel ---> System and Security ---> System ---> On the left pane Device Manger Expand Other Devices. Under Other Devices you will notice a icon with a small yellow error graphic. (Unplug all your other devices attached to any Serial Port) Right Click on that device ---

I am having a problem opening a serial port. I'm using the simple code: s = serial('COM1'); set(s, 'BaudRate', 4800); fopen(s) At this point, I get the message: "??? Error using ==> serial/fopen Error using ==> fopen Port: COM1 is not available. No ports are available. Use INSTRFIND to determine if other instrument objects are connected to the requested device." I plan to exchange NMEA text with a GPS receiver and other devices through communications port COM1 and others. I've used the commands instrfind(s) and s.Status; both of these list the object "s" as closed. I can open files and read and write to them, but I can't connect to a serial port, or the program doesn't see the ports. My operating system is Windows XP , and the version of MatLab I used was version 6.1. Would there be a compatibility problem due to this, or am I missing some intialization code?
