Modbus RTU Slave project based on Microchip PIC 16F87X processor and 24LC128 CMOS Serial EEPROM with I2C interface. PIC Modbus RTU slave supports write and read (3 and 16) functions. The data is stored and read from EEPROM via the I2C bus. You can write/read up to 8000 registers. In a single frame can be read/write 32 registers . The program was written in the HI-TECH C compiler-Modbus RTU Slave project based on Microchip PIC 16F87X processor and 24LC128 CMOS Serial EEPROM with I2C interface.

采用一个标准的基准时钟，在单位时间如1S里对被测信号的脉冲数进行计数，即为信号的频率，由于闸门的起始和结束时刻对于信号来说是随机的，将会有脉冲周期的量化误差，进一步分析测量准确度。因此直接测频法只适合测量频率较高的信号，不能满足在整个测量频段内的测量精度保持不变的要求。若要得到整个频段内较高的精确度，应该考虑等精度测量等其他方法。
