This topic provides a brief overview about USB bulk transfers. I want to show you how to write a USB out endpoint type bulk with lip USB in a simple C program.I have for a long time been wanting to do a Custom USB class driver on the RT106x devices. Bulk Transfers are used for data which are not of the type Control, Interrupt, or Isochronous. Each USB transfer is one packet, which can be up to 64 bytes if using bulk type. If you want to send more than 64 bytes, you have to use multiple packets. I will show you how to implement an USB Out Endpoint Type Bulk Transfer on my Atmega32u4. In my receive callback, after each packet received, it increments the address for the new packet, and at the end of the transfer it swap the buffers.
