EVAL-AD7716EB
GRAPHING DATA
The GRAPH DATA window will allow the user to display the acquired data from any one of the four channels
of the AD7716. The required channel is selected by using the option buttons and when the PLOT GRAPH
button is pressed the data from that channel is displayed.
There are three graphs in this window, the top one displays the 22 bit conversion result, the middle one displays
the status of the Overflow bit and the bottom one shows the status of the digital input pin Din1.
The GRAPH DATA window also has the options for the user to return to the Main Menu or to move to either
of the other two data analysis windows.
Note that when the data from the conversion is displayed the MSB is inverted so that the data is displayed in
straight binary rather than 2's complement. This is done to make the graphing routine quicker to execute.
Fig. 4 shows the GRAPH DATA window as it might appear after reading from the AD7716 Evaluation Board.
