Hi, first thing first, are you able to find any usb detected in "device manager" with the vid=0x16c0 pid=0x5dc? Probably windows did not detect the usb for some reason. Second thing, why are the command location involves temp folder/files? Not sure if it is the way AVR Loader works, never used it before. On the other hand, (...)
Hello, You can do this using a computer with a usb RS232 converter, you can send ASCII data via any serial port terminal software. :-D Hope this helps
CHKDSK is one of the first things to try. Its log seems to report that your file allocation table (NTFS table) is in good shape. (I think 60 reparse records is not a disaster.) Yet you report you cannot read the files themselves. Did you use the IDE to usb adapter previously? Did it always work okay? Did you try the (...)
Dude first try to use GSM Modem Interfaced with PC via UART to usb Board, Use Hyperterminal or Tera Term to write/send AT Commands to GSM and check for first send SMS then receive and Call Like I am posting how to send SMS AT //Followed by CR & LF The response should come" OK " AT+CMGF = 1 //Followed by CR & LF (...)
There are unlikely any problems with short unshielded cables (e.g. 10 or 20 cm) for full speed usb. The problem is most likely about your hub design and hasn't to do with the cabling. You didn't report circuit details, so no further comments possible.
In my view you should first try CDC (comport communication) class of usb than HID.... Because HID class on PIC can interact with HID class device like mouse , key board etc...... I am not sure you will able to do communication with that... Good luck
in usb MODULE 4 line right 1 is voltage , 2 is D+ , 3 is D-, 4 is GND . right then if u connect usb cable to this module then 5 v also coming to the pc right so if 7805 is connected to micro controller and usb module so both 5v is mismatch or not ?
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
Hello, I'm using FTD232R chip in my last project...but it don't work! At first usb connection chip is detected and driver correctly installed....led do some blink. But Windows XP hardware manager tell me "impossible device start - code 10". If I try do disconnect and reconnect some times XP don't detect FTD232R.....but led do some blink (...)
Hi all, i've very strange problem while writing to external eeprom 24lc512. its connected to 18f4550 with 4.7k pullups. eeprom data is sent through usb from PC i am writing eeprom in chunk of 28bytes, writing to first 28 location is ok but when i write to 29th location the 28th location byte gets corrupt. when i try to correct it by (...)
Hi, I am trying to use a usb to serial adapter in my lap for burning PIC. I used TINYBOOTLOADER and WINPIC earlier in my desktop for the same purpose. Now I downloaded the usb to RS232 driver software from this

Hi guyz.. recently i bought Universal usb PIC Programmer.. i tried to load the programming inside the pic,but it not working.. i used winpic 800..and i'm using amd processor.. izzit it because the pic programmer or the software that i used?? if it's software problem, can you suggest me other software to used to load programming to pic..
first you simply try to decode the IR signal in PIC2550 then move on to usb.
Which operating system are you using? Go to device manages>>properties and see if you an find anything connected under usb port. try installing cable driver.
I build a icd2 clone 4550 at Pics rev B (the first),but I don't know how I can install it with mplab. When I connect the icd2 at the usb windows xp don't show the installing new hardware wizard. Mplab is the leatest version 8.4. I try to install manually the drivers into c:\programs\microchips\mplabide\icd2\
I want to develop a system s.t lpc2148 will sense signal from its on-chip ADC. Data from ADC will be stored in memory of lpc2148 and will be transferred to PC through usb communication. I am trying to write code for it. I am referring code from keil library for memory device. But still i am stuck. I have written program for initialization of lpc2
Hi everyone. My name is kumar. need ur help.. I wana build usb Thumb Drive Based key door lock So, the thumb drive will contain a secret password(or d serial number).

PIC 18F4550. After downloading the Brad Minch's LAB1 software for usb, and having read a lot, I have some questions: a) What is the software I should run in the PC (much like Hyperterminal when using old RS-232)? Is it anything like that included with Windows XP? b) LEDs blinking on the PIC side, and on the PC's screen I should see what?
hi everyone, i am writing C on atmega series with Codevision and i want to try AT90usb1286 for the first time. i have been through all the documentation on I have viewed CDC and HID example codes for the device which have been provided in AVRstudio. Now the question is that does anyone know any usb library for (...)
I've try two ICD2 with usb. The first with Cypress Circuit works well, but the Cypress Circuit is not cheap. The second version use the "pingouindunord" version. You can take a look at is website for download everything to make board. the pingouindunord" version it works well too. It's very simple to realize
Hi! every1! I want to find a MCU integrated with usb2.0. Can anyone tell me? Thx! Ken
i want to interface cypress's sl811sh to a xsa-50 fpga board so that the combination can act as a usb host. sl811sh can be used as a low/full speed host controller with one usb port, with 8 bit i/o which can interface to a microcontroller. i need just need basic enumaration and handle bulk transfers. any help is highly appreciated.
I'm using icd2 from microchip. Actually this is my first experience with icd. But i faced some difficulties with icd2 when i try to connect it to a notebook pc via usb. I followed the steps recommended by the documentation but the problem still continues. Every time i start the computer i follow these steps in order to make it recognized by (...)
Maybe this can help You.
Hi first with kind of hub?.... usb 1/2? or etnernet 10M/100M/1G ? For usb hub see at cypress site : Best regards. 8)
