A/D Conversion methods

Sampling processing
It converts analog input sign to digital through general A/D conversion processing and save digital value to Buffer memory. The required time for Sampling processing is 2.1ms interval regardless of the number of channels used.
Average processing
It is used to execute A/D conversion of the channel designated for average account or times and save the average of the accumulated sum on buffer memory. If setting value of time average is specified, it does not read A/D conversion value but receives A/D conversion value gained by time interval and use it for Count average process.
The after decimal point of A/D conversion is ignored.
Setting range of Count average process: 1~255 (times)
Setting range of Time average process: 0~255(x10)ms.
If setting value of Time average processing is 0, only Count average processing is executed.
If Count average process is 10 times
It receives sampling data (2.1ms) 10 times and execute average processing. In other words, the average value of input signal during 2.1ms outputs AD conversion value. In this case, interval time is 2.1ms.
If Count average process is 10times and Time average process is 5(50ms)
Sampling data is done by every 50ms and it executes average processing with those sampling value which is received 10 times. As a result, the average input signal value in 500ms will output as A/D conversion value. In this case, interval time is 50ms.
