4.4 EEPROM Tab

The EEPROM tab interacts with the user EEPROM through the ScratchPad-2 register within the TMP1827 device.

  • Read Blocks: To query the contents of EEPROM, enter an address range and click Read EEPROM. The data is displayed at the right in the preview area as it is retrieved. Note that ScratchPad-2 is a buffer for data being committed to EEPROM, so only the last write to ScratchPad-2 can be read back. Other addresses will respond with 0xFF when the Read ScratchPad-2 command is used.
  • Write Blocks: A single block of 8 bytes can be written to ScratchPad-2, or written and immediately committed to EEPROM.
  • File Operations:
    • Read File loads a CSV file into the preview area at the right. TI recommends to verify read back of edited files before clicking the Write EEPROM From File button.
    • Save File saves the current preview, shown at the right, to a CSV file. TI recommends to save a preview and edit the resulting file.
    • Write EEPROM From File loads a CSV file into preview as it performs the necessary Write ScratchPad-2 and EEPROM Copy (Commit) commands.
