| Abstract: | LPC2132 is a high performance ARM,is very fit for embedded system. This paper introduces the interface technology be-tween LPC2132 and LCM, also introduces program method which use ASM files and C files together in a project,which improve the result of system, given out the method of improving LCM flush speed,given out the method to save data with clock register when system is power off, and introduces the I2C application technology. |
