Note:
At this point, the PICkit Serial transmits the I

C Write Command to the
MCP3421 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 re-check the parameter values
including the order of parameters under the “Script Detail” column. Try
again until the “Busy” LED goes OFF immediately after executing the write
command.
