Is it possible to write directly on the USB pendrive using the AT89S51 MCU. I understand that UART of AT89S51 has to be converted into USB with the help of chips. Also there are modules out there which does this task.
However I want to make both hardware and write software from scratch : from sending data to the UART, then converting it to the USB and storing in a file on USB pen drive.
Anyone who could give starting points?
