SAVING THE SCRIPT FILE AND PROGRAMMING THE MCP3422
CONFIGURATION REGISTER
At this point, the PICkit Serial transmits the I
MCP3422 device. The saved file name will appear in “Users I2C Scripts”
column, and can be re-used any time by selecting the file name.
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, and try
again until the “Busy” LED turns OFF immediately after sending the I2C
command.
