【Abstract】 The article introduces a kind of USB interface design method based on high speed fixed-point DSP chip TMS320F2812. It gives the hardware connection relatively integrated, and describes the basic thought of data transmission in detail. It also briefly presents the control chip AN2131QC of USB interface, and states the selection principle for FIFO component. Finally, it briefly introduces how to program the driver.更多还原
