我看了一个外国的朋友关于相机的程序.试着编个程序看看.-I read a foreign friends on the cameras procedures. Try to look at the series processes.

我用单片机8952和电压比较器339做了一个简单的电容容量测量表，参数大 致如下： 电容测量范围为1pF-9999.99uF，最小分辨力为1pF。分为5个量程，可以自 动切换量程，也可手动切换。 另外，有简单的频率计功能，能测量0-60MHz的数字信号频率（TTL电平）； 还可以产生几个单点频率的方波信号（比如1KHz）。 采用1602LCD作为显示器；4个按键控制；使用24C01保存当前设置值，不用 每次开机重新设置。可单5V供电，也可9V交流供电 -I used the single-chip 8952 and the voltage comparator 339 to do a simple capacitance measurement table, parameters are as follows: capacitance measurement range 1pF-9999.99uF, the minimum resolution for the 1pF. Divided into five ranges, you can automatically switch range can also be manually switched. In addition, a simple frequency meter function, capable of measuring 0-60MHz frequency digital signal (TTL level) can also lead to several single-point-frequency square-wave signal (for example, 1KHz). 1602LCD used as a monitor 4 button control use 24C01 to preserve the current settings, do not reset each boot. Can be a single 5V power supply, 9V AC power supply can also be

自己移植的NXP ARM IAP程序，其部分基本函数源于周立功程序，本人加了详细的注释与移植说明，还有更改编译器环境与启动代码部分说明，按照说明初次使用者便可一试成功-their transplant NXP ARM IAP procedures, and some of its basic functions from Zhou, who procedures, I added a detailed note Notes and transplantation, there are changes in the environment and compiler bootcode explains, follow the instructions to the initial users will be a test success

用8051控制DDS信号发生器，产生1HZ-10MHz的正弦波/三角波/方波-DDS with 8051 control signal generator, producing the 1HZ-10MHz sine/triangle/square wave

使用的同步串行三线SPI 接口，可以方便的连接采用SPI 通信协议的外围或另一片AVR 单片机，实现在 短距离内的高速同步通信。ATmega128 的SPI 采用硬件方式实现面向字节的全双工3 线同步通信，支持主 机、从机和2 种不同极性的SPI 时序，通信速率有7 种选择，主机方式的最高速率为1/2 系统时钟，从机方式 最高速率为1/4 系统时钟。-Use three-wire SPI synchronous serial interface, can be used to facilitate the connection of the external SPI communication protocol or another chip AVR microcontroller, realize in the short distance high-speed synchronous communication.
