Adding serial ports

In addition, the program offers a vast array of configurable options that can be especially useful for testing serial software and hardware. For example, the utility lets two applications share data over virtual COM ports in such a manner that everything written by one program will immediately appear in the other one connected to the other end of the virtual serial port pair.

You can use the software for a variety of purposes, including:. For those of you who are looking for a simple way to create not only virtual COM port pairs but also their bundles with various custom parameters, the app developers offer the Virtual Serial Port Driver PRO version. This edition is tailored for professional use by serial port software and hardware developers and testers. You can easily split a single real RS port into multiple virtual COM ones that will fully emulate the physical port.

Virtual Serial Port Driver Pro makes it possible to create complex port bundles where multiple virtual and real serial ports can exchange the incoming data with all the other ports added to the bundle at a time.

Anytime your application needs to connect to a serial port, the switcher option will link it to a COM port being currently free. For this, you just create a bundle of virtual COM ports that will emulate a single real one. By communicating with one of the virtual ports, your app will, in fact, talk every time to the same real interface. Electronic Team, Inc.

SCL is always on Pad 1. That's it. In this case, when we look at our chart, we can immediately rule out MISO and D38 as those pins are used or not broken out.

Next, let's figure out what code we need. Let's take a look at the Wire. Then we use the pinPeripheral command to set up the pin definition. The next step is to test out the I2C port with the code listed below.

Note: A comma means there are 2 pins that can use that port. A slash denotes 2 different names for the same pin. They are labeled as such. Below is a table that lists what SERCOM ports that are already assigned to a serial protocol for a few development boards.

Let's start with the SAM21 datasheet. This is really where everything comes from. Next are the graphical datasheets. While these are available on the product pages of any board that has one, here they are as a neat little collection. In the past, we had multiple machines setup and configured properly then used GHOST32 old, I know to create an image to deploy. I am wanting to move the process to a better, more easily configured, and update-able long term solution.

Creating the images and customizing them has gone very smoothly. The hurdle I have run into is COM ports. The company I work for develops and sales 3 proprietary pieces of software that rely on Serial communication to control hardware so that very specific and precise tasks take place.

At the moment there are only 2 com ports showing in the virtual machine and I need 6. I have not been successful in finding a way to add more.

I know from other forum posts that you can not connect the COM ports in the VM to the physical ports, even though in my case this would be nice. If there is a way to do this, some guidance would be much appreciated. Or if it is not, some direction towards an alternative.

I currently run everything from a local machine and not a server. In the future that might change depending on the success I have now. Its been a while since I used them but the devicemaster adds virtual com ports to be used for the redirection.

We would use them when the RS device was a great distance from pc. Much better than using the older line driver technology.
