We are developing a board that will be a USB device (not host) using a CP2101. Is there some sort of central registry for Vendor ID and / or Product ID ? This will not be a mass market device but will need to recognizable as a unique device when plugged into a PC. Jim

In the simplest setting, you just use the drivers from ftdi, and the device looks like a com port on the PC. On the microcontroller end, it's an async serial device. Just hook it up to the tx & rx pins of your uart, set the baud rate accordingly, and it's running. Really couldn't

Hi everyone, once more thanks for the answers. I have some more questions though. Would I need a lot of code in the microcontroller side, when using for example FT232BM? Are there any restrictions for my 16 devices to be running together (could I cascade hubs for that?) and what

You probably CAN do it if you bias the second input correctly. This might mean, for example, biasing one input at Vref/2. Or, you might bias both inputs from a common voltage divider and AC-couple the signal into the active input. But you will need to watch out for impedance erro

I am going to test AT43USB355E that is an AVR with USB. This microcontroller needs a SPI EEPROM memory like AT25HP512. You have to load the program on the EEPROM memory. http://www.atmel.com/dyn/resources/prod_documents/doc2603.pdf http://www.atmel.com/dyn/resources/prod_document
