The Read Data from Main ADC Screen
Fig. 12. shows the Main ADC Read Data screen. This is where the user can read a number of samples from the AD7719
Main ADC. The user has the option of either reading data for analysis or display.
When the Read For Analysis button is selected the software will read the required number of samples from the AD7719
Main ADC and store them in an array so that they can be graphed or analysed later. It is possible to read and graph
up to 5000 samples at any one time. The read can be interrupted with a user key press.
When the Read for Display button is selected the software will read one sample from the AD7719 and display its value
in the Current Code text box. The software will continue to read and display the samples until a key has been pressed.
It is possible to add a delay to the read cycle by entering the required number of milliseconds between reading samples.
It should be noted however that the accuracy of the time delay can be affected by other programs running under
Windows, therefore this method is not suitable where equidistant sampling is required. Note the Read Data from Aux
ADC Screen has a similar function to the Read Data from Main ADC Screen, only reading from the Aux ADC and storing
in a seperate array.
