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
Hello all, I am new to usb and am requesting your assistance. Got a communication problem I've been working on now for some time. I am building a RC Robot (a car) with temperature sensor (NTC at dc/dc motor) and the motor speed itself. The main idea is: send the data from the STM32F407 to my pc (status of temp (...)
Hi all, I have wrote a small program for usart module at mplabx ide v2.35. I am using Realterm for communication software. Between my development board and usb port of pc there is a usb-serial converter. My problem is: when i send 0x82, i receive 0x22 most of the time. Interesting thing is that; whenever I control my data (...)
I need high speed communication from the PC to a custom FPGA board. I already tried usb2 chips in usb-TO-FIFO mode. But I want a faster chip. So I thought of using usb3 protocol. Which chip can I use? I don't want to use FTDI chips now and I think Cypress is a good choice. Cypress provides FX3 chips which (...)
This is my Nixie Tube Clock. First I want to use usb to get power and communication. I used STM32F072 48pin series. It has internal RTC and yes, crystalless usb! I wrote PID algoritm for 5V to 170V converter and bingo, i did it with classical boost converter and around (...)
usb HID, VCP, CDC communication methods.
Hi, Please draw a draft of the complete flow of data. Who sends data, in wich format? Who receives the data? What is inbetween? Serial communication (voltage levels, setup)? usb? Klaus
Hi Friends, Using LPc2148 Development board, I've able to detect the my usb device as Mass storage device when connected to the PC. and I can copy and paste the files in the Mass storage device(496Kb) and also able to open, read and write. Now when usb is connected to system I should (...)
Hi, I?m trying to build a midterm system between a costly and highly custom VPX and a platform where each board interfaces with one another by cables. for example: imagine I have an off the shelf mini-itx motherboard, a switch, and 2 network video encoders my idea is to have a back plane that would supply power, serial (...)
Hi Friends, I'm using the LPC2148(ARM7) controller. it has usb2.0 in-bulit support. Now usb act as a Interface b/w the controller and my PC .I wants to send data from PC and controller should able to read it and reply to PC from controller. Just like a chatting in 2-ways. How to do it?what are (...)
hi, I'm doing a project for storing data to the usb sent from PIC controller(PIC30F6012A) using Vinculum(VNC2-32L1B) controller through UART communication. I am creating a file in the usb its created well and Read/write works properly.Now what is my problem is the file is created with the default date(1/1/2010 (...)
You have to make an usb Host which is totaly impossible with 8051. I see two ways: 1. Use more suitable mcu, like ARM with usb Host 2. Use SD card and store data by using file system
Has anyone used the mcp2200 at 1 Mbaud (as the datasheet says) without problems? Actually i want at least 600 kbaud speed. I am currently using FTDI products but due to the low cost of mcp2200 i was wondering if it is capable of those speeds. Thanks
I am trying to interface my PC with 8051 using a CP2102 usb to UART bridge. I tried sending the characters 'M' & 'C' and view them using hyper terminal. I am able to receive the characters but instead of receiving them once, the data is received repeatedly in a loop fashion. I simulated this in Proteus and it works as expected i.e. I'm (...)
Hello.. I am assigned to work on Data acquisition through FT232R usb UART IC. How the data can be received through the hyperterminal in the PC.
The PIC32 will connect to the computer via usb CDC and Ethernet. The PIC32 can either act as an usb host or a device, either connect to the hub upstream port or to a PC usb port. In so far the intended topology isn't feasible. Embedded hosts may include hub support in it's list of targetted devices according to the OTG (...)
Hi, I am using LM3658 for my project which is battery charger IC. It has usb_sel pin which allows to select usb charging current i.e. if it is pulled high, current limits to 500mA and if pulled low current limits to 100mA. So my question is which is good option? Also one more question which puzzles me if mobile (...)
hello friend! i have a problem in my projet. i want to make a usb communication with a microcontrolleur PIC 18F4550 (18f2550) and host(PC). i make all the steps that i found in ours forums but not success. now i dont know if it's a version of my software (MikroC for pic V 5.6). i don't know what i have missing. can i have a help? please. (...)
You are only showing communication errors with the DE2 control panel. To test a more basic thing, does the Quartus II programmer recognize the usb Blaster when performing the hardware setup? Does it see the board with Auto Detect?
