（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)
