DLP3021LEQ1EVM: EEPROM function

Part Number: DLP3021LEQ1EVM

Hello!

What is the function of EEPROM in EVM ? Is it a necessary matching component for MCU or FPGA?
Thanks!

Best regards,

    Hello,

    The EEPROM is not a requirement for the DGP architecture. The EEPROM is available for calibration purposes. For example, the MSP430G2553-Q1 Code Composer Project for DGP shows that the EEPROM is called to retrieve the "calibrated" RGB PWM values for the EVM:

        redpwm = eepromReadWord(EEPROM_ADDR_RED_PWM) & 0x3FF;
    bluepwm = eepromReadWord(EEPROM_ADDR_BLUE_PWM) & 0x3FF;
    greenpwm = eepromReadWord(EEPROM_ADDR_GREEN_PWM) & 0x3FF;

    If the EEPROM is to be omitted from a DGP solution, the MSP430 code must be updated to remove the EEPROM commands from the main function.
