Driving strength control apparatus, driving strength control method and terminal equipment

摘要

The embodiments of the present invention provide a driving strength control apparatus and method and terminal equipment. The control apparatus comprises: a signal receiving unit to receive a test signal transmitted by a peripheral device; a signal sampling unit to sample the test signal received by the signal receiving unit to obtain a plurality of rising edges and falling edges of the test signal; an interval measuring unit to measure the time interval between a rising edge and a falling edge, or between a rising edge and another rising edge, or between a falling edge and another falling edge; and a controlling unit to adjust the driving strength imposed on the peripheral device according to the time interval. With the embodiments of the present invention, the driving strengths imposed on the peripheral device may be made identical, preventing signal deviation and improving the quality of compatibility.
