I need to design a board which should send data to a computer via USB. The data is composed of a packet of about 25/30 bytes sent every 10 ms. A software running on the PC side should receive this information and store it on a file.
I'm wondering if it's better to use an FTDI chip and make the things easy using a virtual COM port or to implement a "true" USB communication (HID?).
I'm afraid about the speed needed to receive and save the string into a file.
What do you recommend? Marco
