（1） 该程序中液晶显示可以实现电压频率，P，Q，S的电能指示，U与I1的夹角，U与I2的夹角
（2） 该程序中液晶显示可以实现电压通道有效值，电流通道1有效值，电流通道2有效值，两路有功功率，无功功率指示，但是这些参数需要配合上位机软件进行系数校正。
（3） 该程序可以实现对两路电流通道的计量精度进行分别校正。在校正的同时保存校表参数到EEPROM，使得样表在重新上电后可以从EEPROM中直接读取校正参数和寄存器配置参数。
（4） 该样表程序可以实现对ATT7053内任意寄存器的读写。
（5） 提供了一份单独ATT7035_SPI的操作软件，使用的是I/O口模拟的方式。
(1) In this program, the LCD can realize the indication of voltage, frequency, P, Q, s, the angle between u and I1, and the angle between u and I2
(2) In this program, LCD can display the RMS of voltage channel, effective value of current channel 1, RMS of current channel 2, two channels of active power and reactive power indication, but these parameters need to be corrected with upper computer software.
(3) The program can be used to correct the measurement accuracy of the two current channels separately. At the same time, the calibration parameters are saved to EEPROM, so that the calibration parameters and register configuration parameters can be read directly from EEPROM after the sample table is powered on again.
(4) The sample table program can read and write any register in att7053.
(5) A separate att7035 is provided_ SPI operation software, using I / O port simulation. (2020-07-06, C/C++, 381KB, 下载2次)

（1）正常计时：秒（60）、分（60）、小时（24）计数；秒计时的频率为1Hz，数码管用动态扫描实时显示计时的小时、分、秒。
（２）整点报时：逢整点蜂鸣器在“59”分钟的第51、53、55、57秒发频率为500Hz的低音，在“59”分钟的第59秒发频率为1000Hz的高音。
（３）校时：
校小时, 显示小时数码管以4Hz的频率递增计数；
校分, 显示分数码管以4Hz的频率递增计数；
校秒, 秒清0。
(1) normal time: second (60), sub (60), hour (24) count; the frequency of second time is 1Hz, the digital tube dynamic scan real-time display time, minute, second.
(2) whole point: a buzzer with a frequency of 500Hz in fifty-first, fifty-third, fifty-fifth and 57 seconds of the "59" minute, and the frequency of 1000Hz in the fifty-ninth seconds of "59" minutes.
(3) school:
The hour is displayed, and the number of the hour digital tube is increased with the frequency of 4Hz.
The score is displayed, and the digit tube is increased by counting the frequency of 4Hz.
School seconds, second clear 0. (2018-07-04, VHDL, 46KB, 下载0次)

用运算放大器做正弦波振荡器在学校时老师就教过，应该是一个常用的电路。现在我做了几款，实际效果都
不理想。哪位做过，可否透露些经验或成功的电路？
Operational amplifier with sinusoidal oscillator do teachers teach in schools that should be a commonly used circuit. Now I have done a few, the actual results are far from satisfactory. Which done, tell us more experience or success of the circuit? (2008-09-18, Others, 693KB, 下载3次)
