hi
i try to use the usb of at90usb162 but i don't know i must to have what information to geting start of course i know somewhat things about usb opration .
i search in net and encounter to the LUFA library but when i look at its file more confused! i don't understand for a simple connection to usb i need which file's and how to use them ?
pleas help me
thanks |

Maybe start by saying what kind of USB device you are trying to implement - there are lots to choose from HID=keyboard/mice/joystick/etc., CDC=UART/comm port, MSD=mass storage (memory stick), MIDI=music etc., app specific, vendor specific.
if it's just to make a UART/comm connection from a PC terminal program to the AVR then see Dean's examples of CDC in LUFA.

thanks alot
well i don't ever know these you say !
can you explain for me ?
are these variety of USB classes?
i just want to connect to usb and for example monitor a tempereture or set point or contrlo speed of a dc motor by chenging the pwm. |

I'd suggest CDC-ACM is the place to start - that way you don't need "special" USB software on the PC - you can just use any terminal program (like Hyperterminal but preferably not Hyperterminal!) and see the logged temperature or type command to the AVR. This means you aren't developing both AVR and PC software at the same time and you know the PC end will work (with the exception of Hyperterminal!) |

this means i don't need to build a dll file for connect to usb?

can i use the terminal emulator in codvision and can i build a terminal with VB(NOT .NET) ?
AND i want to use the exampel of this address :LUFA-111009_3\LUFA-111009\Projects\USBtoSerial
is it good to start with cdc? |

Correct you use any software that can open a COMn port.

Almost certainly yes and yes.

Exactly that USB to serial is the place to start. You can ignore the serial output on the "other side" if you want. |

The USBtoSerial demo is designed to be a full USB to Serial converter IC replacement; i.e. it has internal FIFO buffer for sending and receiving to and from the physical USART.
An easier place to start is LUFA\Demos\Device\ClassDriver\VirtualSerial\, which focuses on virtual serial communications over a USB connection that are generated from within the AVR application itself.

do this oprate in CDC class?
and how much the rate of send and recive deta in class?

Yes. The USBtoSerial is essentially just an extended version of the demo I quoted, which means it contains more features and code than you need for your application. Stick to the simpler demo.

I see varying figures, but with double banked 64KB endpoints I've heard figures as high as 2Mb (256KB/s). Remember that the USB AVR controllers may be USB 2.0 compliant, but they can't actually saturate the USB bus even at USB 1.0 Full Speed.

excuse me i am beginner!
in VirtualSerial folder there are no main.c file this mean that file is exist here are lib for another application?
and what are Doxygen.conf and LUFA VirtualSerial.inf and VirtualSerial.aps files in this folder?
and i want write my code in avrstudio5 so i must copy these file in this folder to my folder application and use the make file that exist here as my make file of project ?
thanks |

I am also a beginner, but

no, the main.c file for VirtualSerial is a same VirtualSerial.c and so in all other projects
mojtaba_led wrote:

Doxygen.conf is config file for make indexed documents of the project and help
VirtualSerial.aps is project file which opens the program: AVR Studio 4

When you run an AVR Studio 5, select menu: File->Import->AVR STudio 4 Project... and in folder VirtualSerial file: VirtualSerial.aps |

i do this and compile but this project write for Atmega128 this means this project can only use for avr that not usb port but i want the usb port of AT90USB162 !??

grep is a search tool - it searches files for text patterns. I asked it to identify any file that contained "main(" and it said VirtualSerial.c
My point therefore is that the file with the main() function in it here is the one called VirtualSerial.c - there's no law that states that the source file that contains main() must be called main.c
As for using AS5 to build. Start simple and use make at the command prompt. |

i change the target to AT90USB162 and compile VirtualSerial.c and program my at90usb162 with FLIP and click on start application then run hyperterminal now i must which com port 1 or 2 or 3 or ...?
this is my sChematic of board that i use :
do i must use library of usart in my application to send and receive data than hypertermianal ? |

In same folder of project, exist file = makefile.
Find this place and change the code as I did:
MCU = at90usb162
Code:
#
# To rebuild project do "make clean" then "make all".
#----------------------------------------------------------------------------
# MCU name
# MCU = at90usb1287
MCU = at90usb162
# Target board (see library "Board Types" documentation, NONE for projects not requiring
save makefile and rebuild solution.  |

i do this but yet pc don't detect my board on usb port !
what do i do for exampel display "hello word" on hyper terminal? |
