1．熟悉硬件仿真工具KD30的使用。 2．修改样本程序 SAMP1a，使无论在计数或停止计数时，按 SW3 均对计数值清零，并停止计数。 3．编制一个秒表程序, 测试精度为0.1秒，按 SW1键启动计数，再按一次 SW1键停止计数。任何时候按 SW3 键停止计数，并对计数值清零。 4．按 SW1键后， 以 0.1 秒为单位开始计数，再按一次 SW1 键停止计数。若按 SW1 键时间超过2秒，则计数值清零，回到初始状态。-1. Familiar with the hardware simulation tool KD30 use. 2. Revised procedures SAMP1a samples, regardless of the count or counts at the end, according to SW3 numerical terms were right, reset, and stop counting. 3. Preparation of a stopwatch procedures, testing accuracy of 0.1 seconds, according to bond SW1 start counting, according to a key SW1 stopped counting. By SW3 any time to stop counting bond and reset the count. 4. By SW1 bond, after 0.1 seconds for start counting, according to a key SW1 stopped counting. If SW1 keys by the time more than two seconds, then reset the count and return to the initial state.

用单片机控制AD9852芯片生成信号的C程序-AD9852 chip with MCU control signals generated C program

这是我大学同学今年的毕业设计项目：基于USB的红外鼠标。红外遥控器模拟鼠标的左右键，还有滚动条。红外接收用HS0038A接收，在这设计中红外处理部分用一块51单片机处理。USB信号处理部分（即USB设备）用51单片机和PDIUSBD12芯片构成-This is my university students graduating this year" s design project: Based on the infrared USB mouse. Infrared remote control analog left and right mouse button, as well as scroll bar. Infrared receiver with HS0038A receive, in the design of mid-infrared processing section 51 with a microcontroller processing. USB signal processing part (ie, USB devices) with 51-chip microcontroller and PDIUSBD12 composition

说明：此程序使用标准PS2键盘输入，LCD1602液晶屏输出显示。此样例仅作测试使用 晶振使用12M或者11.0592M,本键盘使用部分字母和数字测试，其他按键不能使用，用 户可以自行扩展。由于开发板和程序的各种参数，程序中没有使用奇偶校验，不保证没有 误码,校验程序请自行添加。-Description: This program uses the standard PS2 keyboard input, LCD1602 LCD output display. This sample is only used for testing the use of crystal 12M or 11.0592M, this keyboard to use part of letters and numbers tests, other buttons can not be used, users can expand their own. As the development board and procedures for various parameters, the program does not use parity, does not guarantee that there is no error, verification procedures to add your own.

With the program AD9854C.exe one can set and tune the frequency in CW-mode. For use as a receiver LO also IF can be given and the both possible receiving frequencies are printed on the screen. The level in Q-outputs can be varied by giving the wanted attenuation in dB. This function is done by controlling a 12b digital multiplier in the device. In this case the level decreases somewhat with increasing frequency as it does in DDS devices. Alternatively the inverse sinc correction can be chosen, in which case the output is flat and high. -With the program AD9854C.exe one can set and tune the frequency in CW-mode.
