MCP3425 device. The saved file name will appear in Users I2C Scripts
column, and can be re-used any time by selecting the file name.
Note: When you click on the “Execute Script” menu, the “Busy” LED on the PICkit
Serial Analyzer will momentarily turn on and then turn off. If the LED
remains ON, a communications problem has occurred. Remove the PICkit
Serial Analyzer from your computer and recheck the parameter values in
the order of parameters under the “Script Detail” column. Try again until the
“Busy” LED goes OFF immediately after executing the read command.
