SH2165
UPLOADING THE KEYBOARD MATRIX TO THE EEPROM

The Semtech Upgrader program loads a binary file (containing keyboard matrix and custom key data) to an
EEPROM, where it can be accessed by the SH2165.
(This binary matrix file must first be created by the Ultimate KeyCoder Designer program, as described on the
previous page.)
The latest version of the Upgrader program should be used. The latest version of the program can be obtained from
Semtech.
The Upgrader program can upload the file to the EEPROM only if the EEPROM is part of an SH2165 assembly; that
is, a complete and correct circuit (as shown in the schematic) including the EEPROM, the SH2165, and a USB
connector. The keyboard itself need not be present and connected in the assembly; it is irrelevant to the uploading
process.
Using the Upgrader program
1. Connect the SH2165 assembly, with the
EEPROM, to the host PC with a USB cable.
Windows then automatically detects the
assembly as a new USB HID (human interface
device).
Windows may prompt the user to load the
Windows installation media to install the
necessary USB HID files, including
"hidclass.sys" and "hidusb.sys." Load the
indicated media or find the files elsewhere.
The assembly can not work until all
necessary class and driver files are installed.
2. Start Upgrader by double-clicking on the
executable file.
3. The Upgrader window appears. It consists of a message space and 7 buttons: Start, Load, Upload, Download,
Save, Compare, and Exit.
The message space shows which Windows operating system is running. It also shows the version number of
the Upgrader application that is running.
4. Click on the Start button. Upgrader looks for the SH2165 assembly device. Upgrader indicates, in the message
space, whether the device is found or not.
If the device is not found, it might not have been installed correctly in step 1.
5. To upload a binary keyboard-matrix file to the EEPROM:
Click on the Load button. An Open dialog box appears, looking for a file with the ".bin" extension.
If the required file does not have the ".bin" extension, click the down arrow next to "Files of type" and pick
"Any Files (*.*)."
Select the required file. Upgrader loads the data from the file selected into its upload buffer.
Click on the Upload button. Upgrader uploads the data from its upload buffer to the EEPROM.
