To create the read script for the MCP40D18, double click on the ReadAddrA8 script in
the “Example I2CM Scripts” column. This loads the script (see Figure 2-10) into the
“Script Detail” column. Modify the script details so that it looks like Figure 2-12. Then,
in the “Script Name” write the name that you would like to call the script. We chose
“MCP40D18_Read” (see Figure 2-12).
Then click on the “Save Script” button. This will save the script, which can then be
accessed under the “User I2CM Script” column (see Figure 2-11). This script will be
available when the GUI is opened in the future (unless the script has been cleared or
deleted).
