当前LCM的主流接口有并口和串口。并口引脚多,产生串扰,串口则没有诸如此类的缺点。SPI作为串口家族的一员,具有高速同步、芯片管脚少和信号稳定不产生串扰等优点,越来越受到开发人员的青睐。但是,具有SPI的LCM并不是毫无缺点的,市场上以COG(chip on glass)方式封装的LCM大都是基于单工方式传输的,这将给开发带来了非常大的麻烦。本文主要论述基于单工SPI的GUI开发方案,详细地分析了基于单工SPI的GUI的开发开台,论述并分析在GUI开发过程中遇到的问题,最后提出增加虚拟LCD的方案解决这个问题。

是英文 “ Surface mount technology ”的缩写。即表面安装技术,这是一种较传统的安装方式。其优点是可靠性高,缺点是体积大,成本高,限制 LCM 的小型化。 是英文 “ Chip On Board ”的缩写。即芯片被邦定(Bonding)在PCB上,由于IC制造商在LCD控制及相关芯片的生产上正在减小QFP( SMT 的一种)封装的产量,因此,在今后的产品中传统的 SMT 方式将被逐步取代。

sim 文件系统In addition, its quality of service reduces because of reliance on traditional circuit-switched network elements. At that former time, people hoped to build a based system, which could access a centralized server network, would always have access to the latest traffic information and could provide web links. What this trend is a momentous request for mobile services based on high-speed packet data transfer. Hence, a new standard, GPRS, came into being in order to fill people’s bill.

This program would work fine only with a specific flash tool through PC printer port under EPP mode.Program is capable of identifying flash chip manufacturer, device type, capacity,... It also allows user to dump flash data, edit/revise the content of flash chip on the Screen, and re-write them back to the chip.
