    Hi Guys,
    I'm doing an EEG Display system project. the aim is to display signals of the electrodes on a PC. I'm going to use a PIC to acquire and digitize the 8 eeg channels. the digital data needs to be read by the PC via USB port and perform DAC to display eeg signals on PC (laptop).
    Any and all help regarding getting the mcu - usb interface to work will be appreciated.

    Use MCP2221 to send data to PC the rest depends on your programming skills.IC costs around 2-3$.

    @ISB123 thanks for your prompt reply (although I couldn't be so quick) I had just started studying 2221 but my project guide chose to stick with DB9 and RS232 standard. Any way I'm going to do another version of the project based on USB.

    Use an Arduindo; USB is built-in, both for downloading code and run-time communication.
