【Abstract】 TLC320AD50C based on ∑-Δ Technology is implemented in TMS320C5402 to achieve distortion-free sampling of voice signals to satisfy the requirement of next processing . The method of communicating between AD50C and C5402 through McBSP is illuminated to accomplish AD conversion. The software triggering is introduced to start the Secondary Communication between AD50C and C5402, and the interface circuit and the important program segments are also displayed. The hardware connection is simple and feasible and can be applied in the field of voice processing widely.更多还原
