HID USB Driver Library. Table of Contents Motivation The Human Interface Device Class USB Specific Stuff The HID USB Device Interface How to Integrate the Library into a Visual Studio Project How the HID USB Library works internal Where can I get the HID USB Library. Motivation. We wanted to find a new solution to connect our Hardware to the PC via USB because the experience we made with FTDI Chips was not satisfying at all. Ajpd_Soft_ammao_010.jpg' alt='Microsoft Visual Foxpro Driver 64 Bit' title='Microsoft Visual Foxpro Driver 64 Bit' />Whenever you need to connect to a database, you create a Connection object using the ADONewConnectiondriver function. NewADOConnectiondriver is an alternative. The USB controller of our choice was the Maxim MAX3. E that is connected to the microcontroller through a Serial Peripheral Interface SPI. The MAX3. 42. 0E comes without any drivers or libraries you can use to speak with it. This is the reason why I had to develop my own driver. Access3_thumb.gif' alt='Microsoft Visual Foxpro Driver 64 Bit' title='Microsoft Visual Foxpro Driver 64 Bit' />After a day of reading and googling I decided that the best an easiest way is to use the Human Interface Device Class HID. The HID Class is a generic device class which means that all devices in this class are supported by Microsoft Windows and there are already existing DLLs with functions that we can use. The start point for the driver was an article I found in the Microsoft developer network Is That You Writing Better Software for Cool USB Hardware written by Scott Hanselman. Scotts software is based on the USBSharp Class. Luckily the MAX3. E comes with a code sample that configures the controller as a Human Interface Device so we didnt have much trouble to find out how to configure it as HID. The Human Interface Device Class. As mentioned above the HID Class is a generic device class so the driver is integrated in the operating system which makes things easy. If a new HID device is plugged in there is no need of any driver installation. The functions to access and control a HID device are included in the Windows hid. System. 32 folder. If you do not know for sure if your device is a HID device you should have a look at this little application. Microsoft Visual Foxpro Driver 64 Bit' title='Microsoft Visual Foxpro Driver 64 Bit' />It is a part of windows and you can run it with the start run msinfo. Or under Windows Vista just press the Windows Key Type msinfo. USB Specific Stuff. Identify your USB device. USB device are identified by their vendor and product id. Those IDs are consisting of a prefix vid for vendor id or pid for product id and a 4 digit HEX number. The MAX3. 42. 0E for example has the vendor id vid0.

Connectivity solution for ODBCbased applications to access PostgreSQL databases. Usually both values can be changed in the source code of the USB device assumes that you have access to that code. Package Size Communication Speed. HID devices are communicating with the pc through so called hid reports. Those reports consist of 6. Each microsecond one report is send from pc to the USB device and vice versa. This means that theoretical a transfer rate of 6. Kbytes per second can be achieved. The HID USB Driver Interface. The driver is written in C and designed as a DLL, this has the benefit so it is very easy to integrate the drive into a new project. Just import the DLL or the project and you are finished. I tried to keep the interface as simple as possible on the one hand and on the other hand to integrate as much functionality as possible. At the moment it has the following functions USBInterfaceString,String constructor. This method initializes a new instance of the USBInterface class. Parametersvid. The vendor id of the USB device e. The product id of the USB device e. USBInterfaceString constructor. This method initializes a new instance of the USBInterface class. Parametersvid. The vendor id of the USB device e. Connect method. This method establishes a connection to the USB device. You can only establish a connection to a device if you have used the construct with vendor AND product id. Rapidshare Traveller Rpg Adventures'>Rapidshare Traveller Rpg Adventures. Otherwise it will connect to a device which has the same vendor id is specified, this means if more than one device with these vendor id is plugged in, you cant be determine to which one you will connect. Returns. False if any error occurs. Disconnect method. Disconnects the deviceget. Device. List method. Returns a list of devices with the vendor id or vendor and product id specified in the constructor. This function is needed if you want to know how many and which devices with the specified vendor id are plugged in. Returns. String list with device pathswriteByte method. This method writes the specified bytes to the USB device. If the array length exceeds 6. The 0 6. 3 byte of the array is sent first, then the 6. Parametersbytes. The bytes to send. Returns. Returns true if all bytes have been written successfullystart. Read method. This method is used to activate the reading State. If you execute this command a thread is started which listens to the USB device and waits for data. Read method. This method switches from reading State into idle State. By executing this command the read data thread is stopped and now data will be received. Usb. Buffer. EventEvent. Handler method. By calling this method with an event handler System. Event. Handler the add event listener of the USB Buffer is enabled. Thus whenever a dataset is added to the buffer and so received from the USB device the event handler method will be called. Parameterse. Handler. The event handler System. Event. Handler method. How to integrate the HID USB Library into a Visual Basic Project. There a two ways to integrate the HID USB Library into a Visual Studio project. One is to add the library project to your Visual Studio solution. The other way is to add a reference to the USBHIDDRIVER. Add the library project to a Visual Studio 2. Open your Visual Studio solution. Go to File Add Existing Project2. The following Dialog will open. Navigate to the USBHIDDRIVER. Right click on your Visual Studio project and click Add Reference 4. Select the Projects tab. Then select the USBHIDDRIVER and click ok. Add the USBHIDDRIVER. Visual Studio project. Right click on your Visual Studio project and click Add Reference 2. Select the Browse tab. Then navigate to the USBHIDDRIVER. Use the USBHIDDRIVER. Visual Basic 6. The. Net runtime allows unmanaged COM aware clients like Visual Basic 6 applications to access. Net components through the COM interop and through the tools provided by the framework. The USBHIDDRIVER. NET assembly which can not be accessed by Visual Basic 6. Therefore we have to create a type library which can be used with Visual Basic 6. This can be done with the Tool Reg. Asm. exe that you will find in the directory of your. Net framework installation. Create a. bat file in the directory of the USBHIDDRIVER. Then run the bat file. Microeconomia Pindyck 7 Edicion Pdf Descargar. C WINDOWSMicrosoft. NETFrameworkv. 2. Reg. Asm. exe USBHIDDRIVER. USBHIDDRIVER. dll. Now you have to copy both the dll and the tlb file in the same directory as the application which is consuming it. How to use the HID USB Library. Lets say you want to communicate with an USB device that has the vendor id vid0. So the first thing you may want to have is a list of all devices connected to the pc which have the specified vendor id. To do this just make a new instance of the USBInterface class with only the vendor id as parameter. Then call the get. Device. List Mehtod and you will receive a list of the devices that are connected. USBHIDDRIVER. USBInterface usb new USBInterfacevid0. String list usb. I. Device. List For communicating with the device make a new instance of the USBInterface class with the vector id and the product id as parameter. After that, you can call the connect method and a connection will be established. USBHIDDRIVER. USBInterface usb new USBInterfacevid0b.
