"CY7C68013: 从入门到精通，USB固件开发全攻略"

The CY7C68013 is a great starting point for anyone learning about USB and looking to break into the field. I understand the struggles of breaking into the field and some people get stuck on the USB protocol, packet definitions, frame formats, and so on, but end up not understanding anything. From my experience, the protocol aspect can be easily covered by going through a book but the ultimate goal should be how to write the first successful USB firmware. To write USB firmware, it is necessary to understand the Cypress firmware architecture. After gaining experience with endpoints, control, bulk, interrupt transfers, SlaveFIFO, GPIF, and more, then one can revisit the protocol side of things and gain a deeper understanding. At this point, one can try to make changes to the FW.c file - and at that point, you're an expert. First and foremost, let's talk about the tools you need. You will need a CY7C68013 USB board, which you can easily buy on Taobao and comes with plenty of resources. You will also need to prepare the development tools by downloading the Cy3684 development kit from the Cypress website, which is called cy3684_ez_usb_fx2lp_development_kit_15.exe. In conclusion, the CY7C68013 is a great starting point for anyone looking to break into the world of USB technology. By following the steps mentioned and gaining experience in firmware development, one can become an expert in the field. With the right tools and resources, one can easily navigate through the complexities of USB technology and master the art of writing successful USB firmware. This is an exciting journey that will open up a world of opportunities for those willing to put in the effort to learn and grow in the field.
