VIRTUAL SERIAL PORT EMULATOR MAC OS CODE

In priciple you should obtain your own PID and VID for your device from the USB consortium (or more easily from Microchip) but for simple testing and development it is ok to use what I have in the code ie Vendor id = VID = 0x0408 and Product id = PID = 0x000A. If you find any problems, please let me know. It compiles and there is a high probability that it works but I have not had the time to test it after the clean up. You can download the source code from here.ДЄ word of warning about the source code: it was taken from a project that is fully functional but I had to clean it up a bit and remove some personal stuff. IвЂ™ve created a ready to compile sample project that implements a virtual serial port that just echoes back everything you send to it. It sounds a bit grand to call this a library when in reality it is just one source code file and a three files with USB related вЂ#defineвЂ™s. Serial ports are easily accessible from various programming languages including C/C++, Python, Java, VisualBASIC etc. See also USB Indoor/Outdoor Thermometer using PIC18F2550 microcontroller Still it is an other dependency for your project and requires a native library to be linked with your host side application which is more work if you want to do cross platform application development with languages like Java, as I do. And libusb is cross platform which I like a lot. True, there are libraries, I especially want to mention libusb, which make it relatively easy to access and develop a class of USB devices without writing drivers.

If you want to support the most common operating systems, Mac OS X, Linux or Windows, the task just gets bigger, easily beyound the resources of a lone developer.Д«ut if you make your device appear as virtual serial port then the drivers will be provided by the courtesy of the operating system ie all the operating systems have built in drivers for serial ports. To make matters worse using USB often requires writing device drivers which can be even more intimidating. While USB standard is realy not that bad once you get into grips with the basics, it can be very intimidating. Most come only with USB and Etherner connections. One of the hurdless that faces anyone who wants to interface a modern PC with the real physical world is the fact that most new computers have neither a serial port nor a parallel port that could be utilized to interface with external world. The code size is less than 2500 bytes and it requires about 230 bytes of RAM memory and it is capable of transferring almost 1 MB/sec (if only the PIC could generate any data at that speed!). The code has been optimized to use minimal amout of memory (both Flash and RAM) and tuned to work well with the Free SDCC C-compiler. This page introduces a minimal firmware that implements a USB Virtual Serial Port for Microchip PIC18F4550 processor.
