Hid_liber/ Each physical board has its own folder with files defining the matrix layout and other parameters. Hid_liber/board.h Includes board parameters for number of rows/columns, microcontroller specifics, and declarations of the functions to interface the board. Hid_liber/board.c This is where the microcontroller pin-out is defined, and the function definitions for the interface can be found.

Dfu-programmer is a multi-platform command-line programmer for Atmel (8051, AVR, XMEGA & AVR32) chips with a USB bootloader supporting ISP. Most Atmel devices having a USB port come pre-programmed with the bootloader, and this is a lightweight alternative to Atmel's own FLIP/BatchISP program. To talk to it, you can use Atmel's closed-source 'flip' and 'batchisp3' tools, which are awful, or the open-source 'dfu-programmer' which is OK. Using dfu-programmer. Dfu-programmer is an open-source program to talk to the USB DFU boot loader. It is included in Debian and Ubuntu, for which the installation step is (as root).

Hid_liber/ansi_iso_jis.h Pretty much just a dummy file. Hid_liber/ansi_iso_jis.h Here is where the actual layout is defined. [other board specific folders] [.] Makefile Magic make stuff to compile everything correctly. This is where the board and layout to be compiled is selected. README.md avr.h Extra definitions to make life easier.

Load why does my windshield keeps cracking joints. The homeowner will question why it is cracking and did they receive a shoddy job. Durable, high strength, and crack resistant concrete does not happen by accident. Why Concrete Cracks. But it is important that concrete contractors follow well-established guidelines with respect to concrete placement. When installed properly, concrete is one of the most durable and long lasting products you can use around your home.

Avr_keyboard.c The main program code. Hid_listen A monitor that listens to debug data sent back from the keyboard. Compiled on Ubuntu 12.04 64-bit. Download lagu changmin love is the moment.

Print.h Includes functions for debug printing. Print.c Includes functions for debug printing. Usb_keyboard_debug.h The HID keyboard framework supplied.

Usb_keyboard_debug.c The HID keyboard framework supplied. Procedures [ ] Building the firmware [ ] The make system keeps track of what needs to be compiled and how that is supposed to be done. It does not work perfectly for this project. Changing the microcontroller used requires a 'make clean' to be done.

Each board has a section in the beginning of the file. The correct one needs to be un-commented before compiling. Parameters that need to be defined. BOARD = hid_liber // Folder for board specifics LAYOUT = ansi_iso_jis // Required layout for that board. Located in the BOARD folder. MCU = atmega32u4 // Microcontroller the board uses F_CPU = 16000000 // CPU speed B_LOADER = 'jmp 0x7000 ' // Memory location of the bootloader section To compile the firmware run the commands make clean; make Flashing the firmware [ ] Linux [ ] Install dfu-programmer sudo apt-get install dfu-programmer Reset the controller, and run the following commands sudo dfu-programmer atmega32u4 erase; sudo dfu-programmer atmega32u4 flash avr_keyboard.hex; sudo dfu-programmer atmega32u4 start Windows [ ] Atmel Flip [ ] You need the Atmel software installed to your system.

Had the same issue. Seems like a bug. I disabled the screen rotation from task bar(top right) and it went to landscape mode. Just check if this works for you.

Also, xrandr does not work on Wayland. Gsettings set org.gnome.settings-daemon.peripherals.touchscreen orientation-lock true Additionally, the below command ought to disable the orientation plugin completely.

Gsettings set org.gnome.settings-daemon.plugins.orientation active false Also, gnome provides an option to rotate the screen from Settings-> Devices-> Displays-> Orientation setting (search for displays in Activities). Solution: If you're stuck, here's a solution that worked on a 2012 HP Envy 14': sudo apt-get remove iio-sensor-proxy () Then log out and log back in.

Caveat: orientation lock icon is gone from the menu bar and you can't use the gyroscope (if it even exists in your device) to change orientation but that's not a problem since you don't want orientation changes anyway:). If you ever want to re-enable the feature, reverse the process: sudo apt-get install iio-sensor-proxy Observations: The HP Envy did not respond to the gsettings changes suggested here.

It also did not respond to physically rotating the laptop or tilting the screen. Orientation settings were also missing from the settings application. For some reason the auto-rotate code gets triggered after it's been asleep and it's impossible to get it to return to normal without CLI intervention. The laptop does not recognize orientation changes or tilting the lid so I'm not sure why the orientation (rotation) automatically changed in the first place.
