ClockTamerFirmwareUpdate

ClockTamer 1.30

1. Download dfu-programmer (available both for Linux and Windows)
2. On windows you also need to install libusb drivers (included with dfu-programmer)
3. Download the latest firmware Tamer.hex and Tamer.eep
4. Enter firmware update mode.
   1. Power off ClockTamer - disconnect power cord AND mini-USB cable.
   2. Short-circuit `nSS` pin of `GND` (full connector pinout is available [ClockTamerProtocolSPI#ClockTamer_pinout here]). You can short these pins on the bottom side header using any wire or office clip.
      
   3. Connect ClockTamer to a computer with mini-USB cable. LED should be flashing immediately.
   4. Remove short-circuit from `nSS` to `GND`.
5. Update flash (e.g. on windows)

dfu-programmer.exe atmega32u2 flash --debug=100 --suppress-bootloader-mem c:\tools\clock-tamer\board\FW\Tamer.hex

1. Update eeprom (e.g. on windows)

dfu-programmer.exe atmega32u2 flash-eeprom --debug=100 c:\tools\clock-tamer\board\FW\Tamer.eep

NOTE: Since there's no option to read firmware back from device on ClockTamer these commands fail. But it should fail only on validating operation, like this:

<nowiki>

c:\tools\dfu-programmer-win-0.6.0>dfu-programmer.exe atmega32u2 flash --debug=100 --suppress-bootloader-mem c:\tools\clock-tamer\board\FW\Tamer.hex

    target: atmega32u2
   chip_id: 0x2ff0
 vendor_id: 0x03eb
   command: flash
     quiet: false
     debug: 100

device_type: AVR
