Hello Guys, Im working with usb mass storage device boot loader. In which i can able to program my application using pendrive. The code for bootloader is available and working fine. In this case i have to past .hex file of my application to pendrive and rename it as image.hex, but any one can use my application hex file and load into (...)
I purchased Arduino due board. The microcontroller is Atmel SAM3X8E With this board i want to create digital inputs logging system. I want to interface pen drive with this board. Data will store in pendrive in CSV Format. I dont know how to interface pendrive Please if anyone know i am begineer in usb . This microcontroller has (...)
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
Hi All, I am working on a usb host capable of 3.0 speed. When i connect a 3.0 pendrive, Linux in my board detects it as usb2.0 and not as usb3.0. Any pointers on what to check or how to debug? Thanks in Advance!
in our project, we are using 18f4620 controller.some information is saved in external eprom connected to this controller. i want to connect one pendrive (usb) to my board for collecting those data saved. (later, pendrive is connected to pc for display) for that i have to interface one usb female connector with my pic cont
Hi to all i want to know how the set top box usb works and their circuits when we connect it pendrive. How it communicates with pendrive in detail. Any related information please give me thanks
usb spec requires devices to operate with Vbus of 4.4 V to 5.25 V. Beyond this range it's a matter of hope.
I am trying to design a usb pen drive(512 MB) equipped with Bluetooth/WiFi so that even when the pen drive is connected to a computer, we can remotely change the information contained in it. Any ideas? The structure I have thought of is like this. Computer----------(usb port)-----------------(Bluetooth)---------)))))))))[remot
thanks for the info on write protection pin available in usb controllers. Then why no pendrive manufacturer give the wr protection switch in any of their models?( i mean an external switch , like a tab on older floppy discs) AFAIK i have not seen any pendrive with the switch.( very earlier pendrives , some 32MB have a (...)
It is an usbasp programmer closed in housing of old pendrive usb. Assumptions: buffered outputs going into state of high impedance after saving/reading is complete handling of input signal leve
Vinculum VNC1L with the VDFC frimware (like in the VF2F2 dev board) can handle to usb flash drives (not usb floppy or usb harddisk... only pendrives) with the VNC1L you will need an extra microcontroller (i.e. AVR) to manage the communication... or just use the VF2F2
have you tried with another usb pendrive?? how much current do you have at 5v for the vinculum??? i remember having this problem, but it was, or the pendrive doesn't have enought current so the 5V drops and it hangs, or the pendrive FAT is corrupted... maybe if you run a scandisk or checkdsk on the drive, or test (...)
unless you reprogram the pendrive firmware, which needs you to know which controller does it have, it's almost imposible... as it always will try to load as an usb mass storage device... (by the usb class and subclass) have you considered changing the format type (to something beside FAT or NTFS)? or have you considered some encryption (...)
Hello all.... Sorry if i'm in a wrong post. i want to ask about the viculum. want i want to do is to read some file in the usb pendrive. but what i want to do is, i want it to saperate into some folder. i manage to read/write file without the folder but when the file is in the folder and i want to write the file into the folder, it cannot be don

Hi, you need to burn the fedora.iso file to cd/dvd then boot from cdrom/dvdrom. To install though usb, you need to load the fedora into a blank pendrive through: UNetbootin - Homepage and Downloads which will make your usb device bootable. *if you use a non empty usb device, it may be overwrite*
Dear frndz.... i want to design a small project to log a data from 10 temp. sensors into a pendrive . i am using pic pic32mx664f128h as i am using graphic lcd display. i am new to usb data logging in pendrive. please help me proceed this project. how to go about what all things are needed and if i can get a example code in c with pic (...)
Using FPGA? otherwise, You can use usb controllers with two usb port to do this.

Hi I am trying to retrieve the CRC value. If I am not wrong, the CRC is present in every sector of my usb pendrive(read this for harddisks and assuming for usb flash). I couldnt find the location of the CRc.Can anyone tell me where to find it?also will the location of CRC varies with manufacturer? The thing I am trying to accomplish is (...)
I don't think so. Accessing the pendrive requires the PIC to be the usb master (host), but I think it is only capable of being the usb slave. you can use the vinculum usb Host Slave Controller module for this, see link FTDI Products Using this module even the 18F2550 can be used, but I t
You could use a microcontroller with usb host support (such as the Microchip PIC24FJ64GB002). 1. Connect the pen drive to the PIC24 via usb host 2. connect a Bluetooth device such as WT12 to the PIC24 Bluegiga - WT12 Class 2 Bluetooth Module the PIC24 can read the pen drive and send the
Does anyone know the circuit CKT0001 selled by CayennE-k Tecnologia in Brazil ? It has usb interface for a pendrive and supports FAT32+LFN. It seams simple to use and is very cheap. Has anyone ever used it ? Any information about it ? Thanks Luiz
see this ---------- Post added at 18:16 ---------- Previous post was at 18:10 ---------- i think you first need to understand how usb works. You can not normally connect a serial to usb converter to a pen drive. you need a usb host device, what is you p
Usually there is a tool in linux OS to mount or auto mount the usb drives but in any case the usb drive should be available in the file explorer as a drive, you can also check the /media folder and also open a shell and write dmesg to see if the drive has been recognized correctly. Another option is to use shared folders to access
This is not the approach to do any project..................... you should tell what controllers you are aware, programming languages etc. If you are doing pendrive to pen drive then you need usb ports. First select which controller you want to use, PIC, AVR, LPC series etc. Then you ask help here. do you need circuit, code, or entire
There are plenty of posts at edaboard related to the same topic. Mostly FTDI vinculum and processors with usb host capability, eg. Microchip PIC24FxxGB or Atmel AT90usb1286 or discussed. Microchip has complete example projects for usb memory interface.
In the following text I described how to connect normal audo device with mp3 player that consist usb slot for pendrive. For a long time I wanted to add an mp3 function to my old mini – audio system. Device is so good that I rally want to keep it. So idea was to insert some mp3 player with low costs. Choice was a car transmitter mp3 (...)
Hi. I would like to get some suggestions for a project. My problem: There is a hardware that records some files on pen drives. I want to save these files into a PC without human intervention. My Idea: I will build a circuit with 2 usb ports. The hardware will connect into one of them. In the second one I will connect the pen drive
Then you're going to be really sad when I tell you the 18F can't directly talk to a usb slave like your pendrive. You need a usb Host to do that.
the pic are mainly device oriented usb chips that means that you can connect a computer to a pic but NOT connect a pic to any usb peripheral. some recent pic24 can act as a host device, thus connect to a usb pendrive, but they are far more difficult to implement... you had better use a chip like the maxim MAX3420E (...)
Actually, I Want to read the text file contained in a pendrive & store that data in a microcontroller IC. The problem is, how do i interface :cry:the pendrive? That's alot different than connecting 64 LEDs. Anyway the PIC is not a usb host so therefore cannot normally be connected to a usb slave such as a (...)
If ur mother board supports booitng frm usb devices u shd hav no problem. to check go to bios and check the options under boot
I am using 80C196MC for rest of my programming. basically i mean to say that u can use the Cygnal C8051F320 instead of 80C196MC ........... u can use the c8051f320 to interface the EEPROm and usb device
Hello friends, I'm using PCI card in my system for usb port. How can I mount pendrive in my pc. regards sagar please send mail ----
There are OTG (on the go) things out and coming. Really hasn't been too much market pressure for it until the past few years with printers, with being a device for the computer and a host to read a camera etc, and some PDA uses. Could just use a host controller and usb PIC, only doing the host
Hi, I have the HP's Strong ARM core based iPAQ3850 pocket PC with WinCE OS. It got a touch screen, pendrive, wi-fi, bluetooth, InfraRed Com, usb, RS232 (19200bps is minimum), micro-phone, speaker, light sensor, programmable keys with addon modules stuff like for GSM/GPRS for wireless internet etc... I am facing the problem in running any .

I think this is a too demanding task for a 8051. The usb host protocol is very complex. Maybe you should reconsider the decision to use a usb pendrive. I would recommend to use a flash memory card instead, like the ones used for digital cameras: CompactFlash, Memory Stick, MultiMediaCard, SmartMedia Card, SD Card etc. You can find a lot of (...)
Because NT doesn't have native support for usb at all. You can try with service packs but better solution is to change OS. regards meax98
