My question is what is the best (...)
You have to use MCU like pic18f4550 or any other which supports usb. There are also AVR MCUs with usb. See You need to write a application in VC++, VB, VB.net, VC#... which can send data through usb on PC side. See book "Advanced PIC microcontroller projects in C" by Dogan Ibrahim. It has such an example. (...)
Hi, Yes, you should be able to use usb and SPI together as they do not share pins. You could also run SPI and rs232 if you used a Software Usart with some other free i/o pins, don't know if your C library will have one though ? - might find one ready made on the web.
18F4550 is a usb mcu so in your project you would be expected to implement usb protocol stack in the mcu(Freely available). So program the usb mcu either as serial to usb convertor or usb keyboard. Search the net it is quite a popular MCU you will get more help. Use C# or Preferably

Hi every 1....... For my project, im gonna implement a device that communicates with the PC via usb. My mc is pic18f4550. Device is a data logger. Main requirement is building a GUI for this device (using or C# etc) >> when i plug this device to pc first time, it should ask to install drivers.... >> when the
What you need to learn PIC18? PIC16 also can do many thing. I have done projects only use PIC16. I also can use PIC18 like pic18f4550 but I will use that only if I want to use usb module or PIC16 memory not enough.
Hi! im complete the a to d conversion the next step is how to route this binary data to usb .....plz someone helpme
hye,, try take a look at this site.. maybe it you can use the project they make as your reference.. Open Source Framework for usb Generic HID devices based on the PIC18F and Windows - WFFwiki

i'm working on a small project with pic18f4550. i must acquire a sound signal, compress it ( by adpcm ) and then send the data via usb for further treatment... well actually i'm having a problem in sampling the signal. currently my audio input is from the headphones jack in my laptop... when i run a simple sound, i
Hi, First off, perhaps the 4550 usb chip is not the easiest one to start with. usb is not a beginners project and it needs C anyway. Perhaps look at something like the 4520 which is virtually the same but less the complications of usb. The chips contain 3 types of memory - the main one being the On Chip (Flash) (...)
