I am deploying a Qt application to a beaglebone black that is running Stretch. I am attempting to use linuxfb with libinput to handle touch events. The touch screen input was inverted, so I set the Coordinate Transformation Matrix with a .conf file. The touch works correctly on the desktop, but is still inverted in my Qt app.
Here are my environment settings for Qt:
QT_LOGGING_RULES=*=true
QT_QPA_EGLFS_HEIGHT=600
QT_QPA_EGLFS_PHYSICAL_HEIGHT=92
QT_QPA_EGLFS_PHYSICAL_WIDTH=155
QT_QPA_EGLFS_WIDTH=1024
QT_QPA_FB_DRM=1
QT_QPA_PLATFORM=linuxfb
With the above settings, the app renders correctly and is responsive, but the touch input is inverted.
Here is the Qt console output when running with these parameters:

Using this configuration, I can only run the app if the beaglebone has a bare xsession running. The app renders correctly, but is laggy, and the touch is still inverted.

How can I invert the touch input inside my qt app?
The solution ended up being to use evdev touch in my app and use QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS to fix the input events.
My final run environment ended up being:
QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS=/dev/input/event1:rotate=180
QT_QPA_FB_NO_LIBINPUT=1
QT_QPA_PLATFORM=linuxfb

I am running a Hello world QML program and config as above.
QT_QPA_EGLFS_SWAPINTERVAL=0
QT_QPA_UPDATE_IDLE_TIME=0
QSG_RENDER_LOOP=basic
I test the QT_QPA_EGLFS_SWAPINTERVAL via PVRTrace https://www.imgtec.com/developers/powervr-sdk-tools/pvrtrace/
it shows the eglSwapInterval did set properly as above.
But the problem is the program stuck on 60FPS.
Why I cannot disable the V-Sync.
The short answer is that vsync behavior is entirely platform dependent. In reality eglSwapInterval() is actually just hint and it is implementation-defined whether it actually does anything at all. On most platforms it doesn't - e.g. on Android you can neither disable it nor fix FPS at 30. Suggest raising this with the platform provider.
I want to calculate space left on my embedded target.
The Arduino IDE shows this in the output window:
Sketch uses 9544 bytes (3%) of program storage space. Maximum is 262144 bytes.
avr-size has -C option that shows "xx% left":
$ avr-size -C --mcu=atmega32u4 build/myproject.hex
AVR Memory Usage
----------------
Device: atmega32u4
Program: 8392 bytes (25.6% Full)
(.text + .data + .bootloader)
Data: 2196 bytes (85.8% Full)
(.data + .bss + .noinit)
However, I'm actually writing a CMake file to develop code for an Arduino board with an Arm Cortex M0 CPU, so I use arm-none-eabi-size, which shows the code size like this:
[100%] Built target hex
text data bss dec hex filename
8184 208 1988 10380 288c build/myproject
[100%] Built target size
*** Finished ***
Is there a way to calculate the program and data space left on the device? Or do I need to regex the output and calculate percent of a hard-coded value?
If you are using arm-none-eabi toolchain, you can add linker option -Wl,--print-memory-usage which prints RAM and Flash usage in percentage. Output looks like this:
Memory region Used Size Region Size %age Used
RAM: 8968 B 20 KB 43.79%
FLASH: 34604 B 128 KB 26.40%
I am using make file generated by CubeMX, to enable this print I added the option at the end of LDFLAGS line. For CMake this thread might be useful.
I recently have restarted to program in OpenCL and faced a beignet related error when I run the program like below:

I need to write a udev rule for a particular keyboard which does not seem to have any unique attribute against which to match.
The lines below are the output of udevadm monitor upon insertion of the device. Is there something here I could use to uniquely identify this keyboard?

Edit:
Below are the lines from plugging the keyboard into a different usb port. As far as I can tell, it seems that there is no information that remains constant.

So I have created the following udev rule:
SUBSYSTEM=="usb", ATTR{idVendor}=="0x04b3", ATTRS{idProduct}=="0x3025", RUN+="/home/myuser/bin/udev_jap.sh"
However, nothing is triggered so far. And strangely, the idVendor and idProduct information doesn't show up on udevadm monitor. Does this mean udev can't match against these attributes?
This is an old question, anyway:
You have to remove 0x hexadecimal prefix.
Note that ATTR and ATTRS are different, but for your case both should work.
Your script udev_jap.sh should start with shebang #!/bin/sh or run shell itself:
RUN+="/bin/sh /home/myuser/bin/udev_jap.sh"
Try this:
SUBSYSTEM=="usb", ATTR{idVendor}=="04b3", ATTR{idProduct}=="3025", RUN+="/home/myuser/bin/udev_jap.sh"
