I have a notebook since a few month and I have just notice that I have no serie port (COM).
I dont mind but how can I do for using the USB 16 controller. Can I install a com driver and where can I find that.
Please help me !
I’ve had the same problem, and you have a few options:
Yes, you can get a Pololu USB 16-Servo Controller (https://www.pololu.com/products/pololu/0390/). It will work like a virtual com port, so long as you install the driver (https://www.pololu.com/products/pololu/0390/usc01a.zip) before you plug it in. You can even connect other logic-level serial devices (motor controllers, etc) to the serial output pin of the USB servo controller. You will need a USB A to Mini-B Cable (https://www.pololu.com/products/misc/0130/), which Pololu also sells. These are pretty standard for small USB devices like digital cameras, and you might already have one lying around.
If you don’t need to control so many servos, or if you want to save a little money and don’t mind doing more of the soldering yourself, you can buy a Pololu USB-to-serial adapter (https://www.pololu.com/products/pololu/0391/). It will also appear as a virtual com port on your laptop if you install its driver (https://www.pololu.com/products/pololu/0391/usb01a.zip) first. This device will allow you to use ANY of Pololu’s serial devices, as it outputs logic-level serial data.
You can buy a USB to Serial adapter cable. This might be the best option for you if you have lots of old serial devices that you will want to use on your laptop. You would also be able to use any of the Pololu serial servo controllers, since they all take RS-232 data. The serial 8-servo controller (https://www.pololu.com/products/pololu/0727/) and serial 16-servo controller (https://www.pololu.com/products/pololu/0240/) even have DB9 connectors built in, so you can plug your adapter cable right into them. You can also use a Pololu micro serial servo controller (https://www.pololu.com/products/pololu/0207/) by connecting Pin 3 from your serial cable to the “COM” pin on the controller, and Pin 5 from the cable to ground.
