Implementation and Application of DSP-LCD Driver Based on Framebuffer

The implementation of LCD driver based on Framebuffer in uClinuxwas introduced. Firstly describe the Framebuffer processing mechanism and the underlying driver interface functions, and conduct a concrete realization on ADSP-BF561 platform; Secondly, based on Framebuffer, the embedded graphical user interface MiniGUI was described briefly, and conduct a transplant on ADSP-BF561 platform; Finally, the actual test results verify the correctness of the work.
