AT mega88 A/D转换的实现 采用的是外部中断进行控制A/D转换

　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.

51汇编语言，格式为.chm文件，这个好象就是九十年代初孙涵芳（如果我没记错的话）写的一 本书后附的子程序。子程序不全对，至少有个除法的余数有问题，扩大了2倍，我记不清是哪个了，你把其中的一个左移语句去掉就行了，别的记不得了。欢迎常联系。-51 assembly language format. Chm documentation, It was like the early 1990s-wu (if I remember correctly so) wrote a book attached to the subroutine. Subroutine incomplete right, at least a division of the remaining problems, and expanded two times, I can not remember clearly what is, you put one of these bits removed statement on the visit, other reporters unnerving. Welcome regular contact.
