The scheme of USB interface chip+ FPGA+ self-designed 429 bus driver circuit
has been adopted to achieve the design of USB-429 bus interface. In this scheme,
Cypress corporation’s USB slave controller chip CY7C68013 has been used to
communicate with a host computer through USB interface. Instead of dedicated bus
interface chip, FPGA has been used to complete data format conversion and protocol
processing with less cost and more flexibility.
