ARM处理器具有高性能、低功耗、低成本等显著优点,已成为高性能、低功耗嵌入式微处理器的代名词,是目前32位、64位嵌入式微处理器中应用最为广泛的一个系列。采用S3C44B0X实现的嵌入式系统液晶屏,其内置的LCD控制器主要提供液晶屏显示数据的传送、时钟和各种信号的产生和控制功能。SG322400CNCWA与S3C44B0X液晶显示模块硬件连接时,通过74HC245把S3C44B0X的3.3V电压升压到LCD显示模块需要的5V电压,从而解决了液晶与ARM的电压不匹配问题。
ARM processor with significant performance advantages, low power consumption, low cost, has become synonymous with high-performance, low-power embedded microprocessors, 32-bit, 64-bit embedded microprocessor is currently the most widely used series . Using S3C44B0X embedded system LCD screen, the built-in LCD controller provides LCD screen display data transmission, clock and a variety of signal generation and control functions. SG322400CNCWA and S3C44B0X LCD module hardware connection, through the 74HC245 S3C44B0X the 3.3V voltage boost to the LCD display module 5V voltage required to solve the LCD and ARM voltage does not match the problem.
