Usb Applications

PID and VID are fundamental identifiers in usb that (amongst other things) let the host determine the correct drivers to use. They are documented in most manuals on usb. Susan

is a free open source editor (IDE) for C or C++ and uses the free GCC compiler. is a C++ library that lets developers create applications for Windows, Mac OS X, Linux and other platforms with a single code base. This will have the plugins for buttons, graphs, etc wiki.codeblocks

Hi I used to drive the 3G usb modem from my application using AT commands over Virtual com port Modern 3G usb modems are not listed as virtual comm ports , How can I drive them? Can I use my old applications with them? Regards Hossam

Does anyone know of any useful reference designs or papers for usb Type-C battery charging applications? I've never worked with a battery system charged from usb before, and so I'm a little unclear about the EMC requirements and what kind of filtering and circuit protection might be required. Also not aware of what sort of charge controllers (...)

Hello, I am using pic32mx795f512l and i am trying to code for external eeprom (25LC256) to store the last value of LED. I want to use SPI communication for EEPROM. I need sample code to done this. Please help me with some sample code. Thanks in advance

I want to communicate my microcontorller(PIC18f4550) with PC using usb, can someone help me in it.

UART from MCU using usb to RS232 converters are good enough to send data at real time to PC as MCU's are very slow in data sending compared to PC. I used it myself in some applications. But it is also fine to use AR90usb162 as the usb controller is built in. But u have to develop usb driver for both (...)

Hello, I am trying to develop the usb interface with a PIC18F4550 with the help of a EasyPIC6 Development Board. I am using MPLAB v8.56. After looking through the usb device example (HID Device Custom) on Microchip Libraries for applications (MLA), I could build the hex file successfully for my project. Then, I used mikroProg Suite to (...)

Hi Everyone! I want to communicate between pic18f4550 and pc through usb communication, i have written the code for pic and when i connect it to the pc, the pc should detect and install the drivers for this. but pc does not even detect it. i m posting the code here so please help me what might be the problem. void main() { // unsigned

Guys, What's the most popular usb host controller ? is it Vinculum ? How to interface it with uC ? AVR or PIC ? thanks

I use Debian and Ubuntu. I program in Python and made a program to log the output of a multimeter (usb) and a program to help me to operate an impedance bridge that has many modes and involves a lot of math. So now I just follow the program and feed it with the data and the it gives me all the right values like Z, R, jX, C, L, Y, G, jB, Rl, Rho etc

dont rely on usb for your applications. usb requires a working driver, and you will have to update your usb driver at almost each major os update build an ethernet interface, it's not much work, and it will still work in decades (and it would have worked 30 years back...)

Do you have breadboarding supplies and benchtop power supply? There are many, many, many development kits of the AMR7TDMI based parts from several sources, including starter kits from IAR, Keil, Rowley Crossworks, and more. These kits are often more "turnkey" and come with what you need for hardware and pluf into a PC usb port with a cable, usua

Hello! I want to make a project to communicate with usb! PC <-> development board I need some idea to do that. I'm thinking to use some avr with internal usb module. but who? :( someone with support maybe...? maybe it's difficult to me the pc programming part What's the easy way to use? Visual C++? i want to have GUI. :( and in part of uC pr

I am trying to make an application with C++Builder which communicates with a PIC16F877A which has a RS232 interface. Unfortunately my computer only has usb ports so I have bought a usb to RS232 converter cable. Well I am a complete beginner to C++ Builder so really at this point I don't even know it will be possible to do this... Any help and adv

hello! I am new to hfss v12 software. i am designing an usb dongle antenna for mimo applications as a project for my graduation.i am held up at the excitation stage.i have attached the reference paper for clarification. i have made the structure in hfss but struck at the excitation.i was unable to give lumped port because b

I'm building a system that will get samples from external ADC (SPI) and send to my computer through usb interface, basically a monitoring system. The final system will consist in 24 channels, each one with 24 bit resolution and sampling rate of 5kHz. Given this requirements, serial emulation would not fit in my system. I'm new on usb devel

Hello, today i want to introduse my usb HID Host driver for Windows. The AHID Library is a Dynamic Link Library (DLL) and can be used with many programming languages. It comes with several example applications for the Visual Studio 2010 (C++, C# and VB). You can download it from here: - usb HID drivers f

I use usb2.0 for CNC using a PIC18F4550 as the CNC controller and have not experienced any issues with it. The host PC transfers G-Code instructions to a buffer on the PIC, such that the PIC has a complete movement instruction on chip. The host is always waiting on the PIC (i.e. waiting on the CNC system) so no latency.
