The DataView software displays the digital output of the MCP3221 ADC in a graphical
format on any Windows
transferred from the MCP3221 to the PC, converted to decimal and then plotted on the
graph shown in Figure 2-2. Each consecutive conversion is added to the right side of
the graph. The y-axis of the graph displays the output codes that have been collected
and automatically scales for any given output code range.The x-axis of the graph
automatically scrolls to the left once the entire graph has been filled with samples.

The DataView software can be used to record MCP3221 conversion data and then to
save to a ASCII text file by selecting "File >> Save Data" from the Program menu. The
frequency of conversion and subsequent data log is user-selected under "Device >>
Configure" from the Program menu. Here the number of samples and polling interval is
selected. Please note the polling interval refers to the PC to PICmicro MCU polling
interval, not the PICmicro MCU to ADC sample rate.
