Abstract
The LCD driver in Linux based on ARM11 embedded system was studied. A method of LCD driving design on the basis of the framebuffer, and two methods on the basis of reading and writing GPIO directly were analyzed. The advantages and disadvantages of the three LCD drivers were summarized by testing. A LCD control mode was implemented by combining the framebuffer and direct both reading and writing GPIO driver. The application indicates that this method can obtain following advantages: faster speed, simpler driver and stronger transplantation.关键词
