Daughter Board’s EEPROM Memory Manipulation
Each daughter board contains EEPROM memory which
bears all necessary information:
• identification of plugged daughter board for its
auto−detection in GUI SW,
• version of the board, manufacturing date, location,
• parameters of assembled components (used for
calculations on high level Application control tab),
• content of SPI control registers can be stored here from
“Control registers” tab
Window “EEPROM Device configuration” serves for
manipulation with EEPROM memory. Identify on which
SPI channel the EEPROM memory is located and manually
enter the number into “SPI channel” text box and click Read
button. Memory content should be read out and all related
