HD44780液晶驱动，KEIL C51

开发环境为：iarEWARM5.20 语言为c语言 2378的启动文件，为EWARM5.20 例程中的文件 利用lpc2378的io口控制ocmj12232c-1液晶的程序。程序有详尽接口说明和完整的注释。ocmj12232c-1是st7920控制的显示模块。使用lpc2378移植的程序这是第一个。-Xi Yuan-kai为alas iarEWARM5.20 To:为c Pang Pang Sheng Sheng-hung 启 cavity 2378 ， glass text为bird

C51智能反编译器-C51 intelligence counter- compiler

RAM的硬件测试程序,经本人测试已经没有问题-RAM hardware test procedures, as I have no problem testing

单片机内置USB调试固件程序,用于51单片机-MCU built-in USB debug firmware for the microcontroller 51. . .

液晶方面的一些资料文件 希望有所帮助关于51语言-LCD some hope that help information paper on the 51 language

c8051f020里面自带的温度传感器的使用程序，经调试通过。-C8051F020 own temperature sensor inside the use of procedures adopted by the debugger.

　C8051F330/1 MCU 有一个可编程内部高频振荡器、一个可编程内部低频振荡器和一个外部振荡器驱动电路。可以通过对 OSCICN 和 OSCICL 寄存器编程来使能/禁止内部高频振荡器和调节其输出频率（参看振荡器框图）；可以通过对 OSCLCN 寄存器编程来使能/禁止内部低频振荡器和调节其输出频率（参看图9.3）。系统时钟可以由外部振荡器电路或任何一个内部振荡器提供。表9.1给出了内部振荡器的电气特性。 -C8051F330/1 MCU has a programmable internal high-frequency oscillator, a programmable internal low frequency oscillator and an external oscillator drive circuit. Can register on OSCICN and OSCICL programming to enable/disable the internal high-frequency oscillator and adjust its output frequency (see diagram oscillator) OSCLCN can register through the programming to enable/disable the internal low frequency oscillator and adjust its output frequency (see Figure 9.3). System clock can be external oscillator circuit, or any provision of an internal oscillator. Table 9.1 gives the electrical characteristics of the internal oscillator.
