Serial Port And Visual Basic
Helm PCB USB HID Template for Visual Basic 2. Published on 2. 9 November, 2. Introduction. With the decline of serial and parallel ports from modern computers, electronics hobbyists are turning more to utilizing USB or stick with old computers for their legacy ports. Unfortunately, unlike serial and parallel ports, USB is far from simple and so it can be daunting to try to develop hardware and software for it. However, there are many hardware and software solutions that make developing USB device much simpler. Some PIC microcontrollers now come with a USB Serial Interface Engine SIE that handles the very low level parts of the interface. However, writing firmware to work with the SIE can still be a difficult task. Luckily, many PIC compilers come with USB libraries that work out of the box and are dead easy to use. The code generated by these compilers tends to produce a USB Human Interface Device HID as these devices do not require custom drivers to be written because Windows has them preinstalled. However, you still need to write your own PC software to read and write data from your USB device. This article shows you how to do this. Visual Basic Template. The Visual Basic template, which you can download at the bottom of the page, generates the basic code framework that is needed to interface with your USB device. All you need to do is set the VID, PID and buffer sizes going into and out from the PC. After that youre ready to read and write data. To give credit where credit is due, I did not write the code that is in the template the code is based on the code generated by the Easy. Bryce 6.0 Iso.

Computer ports have many uses, to connect a monitor, webcam, speakers, or other peripheral devices. On the physical layer, a computer port is a specialized outlet on a piece of equipment to which a plug or cable connects. Electronically, the several conductors where the port and cable contacts connect, provide a method to transfer signals between devices. Physical shapeseditPort connectors may be male or female, but female connectors are much more common. Bent pins are easier to replace on a cable than on a connector attached to a computer, so it was common to use female connectors for the fixed side of an interface. Computer ports in common use cover a wide variety of shapes such as round PS2, etc., rectangular Fire. Wire, etc., square Telephone plug, trapezoidal D Sub the old printer port was a DB 2. There is some standardization to physical properties and function. For instance, most computers have a keyboard port currently a Universal Serial Bus USB like outlet referred to as USB Port, into which the keyboard is connected. Physically identical connectors may be used for widely different standards, especially on older personal computer systems, or systems not generally designed according to the current Microsoft Windows compatibility guides. For example, a female 9 pin D subminiature connector on the original IBM PC could have been used for monochrome video, color analog video in two incompatible standards, a joystick interface, or for a MIDI musical instrument digital control interface. The original IBM PC also had two identical 5 pin DIN connectors, one used for the keyboard, the second for a cassette recorder interface the two were not interchangeable. The smaller mini DIN connector has been variously used for the keyboard and two different kinds of mouse older Macintosh family computers used the mini DIN for a serial port or for a keyboard connector with different standards than the IBM descended systems. Electrical signal transfereditElectronically, hardware ports can almost always be divided into two groups based on the signal transfer Serial ports send and receive one bit at a time via a single wire pair Ground and. Parallel ports send multiple bits at the same time over several sets of wires. After ports are connected, they typically require handshaking, where transfer type, transfer rate, and other necessary information is shared before data are sent. Hot swappable ports can be connected while equipment is running. Almost all ports on personal computers are hot swappable. Plug and play ports are designed so that the connected devices automatically start handshaking as soon as the hot swapping is done. USB ports and Fire. Wire ports are plug and play. Auto detect or auto detection ports are usually plug and play, but they offer another type of convenience. An auto detect port may automatically determine what kind of device has been attached, but it also determines what purpose the port itself should have. For example, some sound cards allow plugging in several different types of audio speakers then a dialogue box pops up on the computer screen asking whether the speaker is left, right, front, or rear for surround sound installations. The users response determines the purpose of the port, which is physically a 18 tip ring sleeve mini jack. Some auto detect ports can even switch between input and output based on context. As of 2. 00. 6, manufacturers have nearly standardized colors associated with ports on personal computers, although there are no guarantees.

Pastel green Speaker 18 stereo TRS minijack. Fire. Wire ports used with video equipment among other devices can be either 4 pin or 6 pin. The two extra conductors in the 6 pin connection carry electrical power. This is why a self powered device such as a camcorder often connects with a cable that is 4 pins on the camera side and 6 pins on the computer side, the two power conductors simply being ignored. This is also why laptop computers usually have only 4 pin Fire. Wire ports, as they cannot provide enough power to meet requirements for devices needing the power provided by 6 pin connections. Optical light fiber, microwave, and other technologies i. Optical connections are usually a polished glass or plastic interface, possibly with an oil that lessens refraction between the two interface surfaces. Microwaves are conducted through a pipe, which can be seen on a large scale by examining microwave towers with funnels on them leading to pipes. Hardware port trunking HPT is a technology that allows multiple hardware ports to be combined into a single group, effectively creating a single connection with a higher bandwidth, sometimes referred to as a double barrel approach. This technology also provides a higher degree of fault tolerance because a failure on one port may just mean a slow down rather than a dropout. By contrast, in software port trunking SPT, two agents websites, channels, etc. ISDN B1 6. 4K plus B2 6. K equals data throughput of 1. K. Types of portseditDigital Visual InterfaceeditDisplay.
