The HIDBootloader is included in Microchip Libraries for Applications (MLA). NISSE uses MLA v2013-12-20. The HIDBootloader is a Qt application; it can be built on Windows, macOS, and Linux. A precompiled binary for Windows is included in the MLA under C:\microchip\mla\v2013_12_20\apps\usb\device\bootloaders\utilities\bin\win\HIDBootloader.exe.


Caution: HIDBootloader in MLA v2013-12-20 might not work with your operating system version. In such cases, please use HIDBootloader included in a newer MLA.


To update the firmware, please complete the following steps:

  1. Connect the NISSE keyboard to your PC holding the ESC key down. The red LED will start blinking to indicate that the keyboard is in the bootloader mode.
  2. Press the [Import Firmware Image] button in the HIDBootloader toolbar, and select the firmware HEX file (esrille.nisse.#.##.hex) to update.
  3. Press the [Erase/Program/Verify Device] button in the HIDBootloader toolbar to start the firmware update.
  4. While the update is in progress, please do not turn off your PC, or unplug the keyboard from your PC.
  5. Press the [Reset Device] button in the HIDBootloader.
  6. Verify that the red LED has stopped blinking, and your keyboard is ready to use.

To build the HIDBootloader on Mac or Linux, please complete the following steps:

  1. Download a Microchip Libraries for Applications (MLA) packaged for your operating system.
  2. Download and install Qt5 using the package manager of your operating system or from Get Qt.
  3. Run Qt Creator (the Qt5 IDE), and select [File]-[Open File or Project] and open the project file for the HIDBootloader stored at mla_v2013_12_20/apps/usb/device/bootloaders/utilities/qt5_src/HIDBootloader.pro.
  4. Select [Build]-[Run] to start the HIDBootloader.
