MEMORY TAB
The Memory Tab gives the user access to all 32 bytes of SRAM and all 48 bytes of EEPROM inside the
DS2781. They are separated into four sub-tabs for convenience. Any value can be modified by clicking in
that address’ text box and typing a new value in hexadecimal format. The Write button will copy the
entire block of data to the corresponding location inside the DS2781 (Scratchpad RAM on the EEPROM
blocks).
The Read button will update the entire block’s text boxes with data from the DS2781
(Scratchpad RAM on the EEPROM blocks). Sub-tabs displaying any EEPROM data will also have Copy
and Recall buttons to allow the user to transfer the data between Scratchpad and EEPROM memory
internal to the DS2781. The Permanently Lock Block 0/1 buttons will permanently store the data
currently located in that block’s EEPROM. Warning – this data can never be changed once locked. Verify
your data first by issuing a Recall and a Read.
The Net Address Sub Tab allows the user to perform a Search Net Address to find all of the 1-Wire
devices on the 1 Wire bus. All devices found on the bus will be listed in the Net Addresses field. To
communicate to any device on the bus, click on its address inside the Net Addresses field to select it. The
program will now use this Net Address for all operations until a different Net Address is chosen.
