2 Gain Table Format

The gain table of the ATWINC15x0 device is in *.csv file format. It is recommended that this .csv file be opened with Notepad++. Microchip recommends using the default gain table and editing the gain values based on the user requirement. The default gain table can be accessed from the location mentioned in Section 7 (Gain Values Download) of the ATWINC15x0/ATWINC3400 - Integrated Serial Flash and Memory Download Procedure Application Note (DS00002378).

The following table shows the format of the Gain Table. This table must be filled with the Digital Gain (DG) values, which are unique for given RF channels and data rates. The user can update 8 different gain values per channel.

The first row represents the RF channel number and the first column represents the data rate. The Digital Gain (DG) value must be determined by the user for all the combinations of the RF channel numbers and data rates. No changes need to be made to the Specific Configuration Region.

To enable the CR+LF, in the Notepad++ menu, go to View>Show Symbol, then select the Show All Characters option. See the following figure.

Note: Microchip recommends following the gain table template as it is in the WINC1500 Firmware Upgrade Project. If upgrading to the newer version of the firmware, use the gain table template from the latest firmware version package to update the gain table with required DG values.
