Maxim Integrated OneWireViewer, Version 1.5 - Manual (Page 16)

Allows the contents of the selected bank to be changed.
Allows the new data to be copied to the selected bank.
Sample Memory Tab with Scratchpad Selected
Notes:
The number of the memory banks and their respective names depend on the type of the device viewed.
The display format in the content field varies with the device and memory bank selected. For most devices there are 2 x 16 bytes per page. With EPROM
devices, there are n x 8 bytes (special function registers only). With the DS1977 the format is 2 x 32 bytes per page.
If the selected memory bank is a scratchpad, the target address TA1, TA2, and the E/S byte (offset) are displayed above the scratchpad contents. With other
memory banks and depending on the device, one will see device-specific information associated with a memory page.
To write to the device, select the bytes to be changed in the Contents field, type new data, and click on Commit Changes. This method applies to all memory
blocks shown in the Memory tab. The viewer will perform the necessary steps (e.g., write scratchpad, copy scratchpad) to update the device memory or
register. See the section Auxiliary Functions text editor (hex/ASCII editor) for more details.
Writing to an EPROM device requires a port adapter that supports 12V programming pulses.
File
The File viewer displays the file names and directory structure of the selected 1-Wire memory device connected to the OneWireViewer. The user can format the
device, create/delete directories and files, edit files (see Hex Editor and ASCII Editor), resize files, and write them back to the 1-Wire device.
The File viewer supports the 1-Wire File Structure. (See application note 114, " 1-Wire File Structure .") The tab of the File viewer consists of two areas: Directory
(center left), and File Contents (center right). In addition, there are eight command buttons. The vertical bar between Directory and File Contents can be moved
horizontally to change the size of the areas. Depending on the size of the file tab, there may be scroll bars for the Directory and File Contents area. The File viewer
applies to all devices that contain general-purpose user memory. See the Supported Devices table above for the list of devices.
