NOTE: Qt is using double for qreal on this system. This is binary incompatible against Qt 5.1.

Configure with '-qreal float' to create a build that is binary compatible with 5.1.

Info: creating super cache file /home/minimonk/src/qt-everywhere-opensource-src-5.3.2/.qmake.super


Qt is now configured for building. Just run 'make'.

Once everything is built, you must run 'make install'.

Qt will be installed into /usr/local/Qt-5.3.2

심심해서 일단 받아봄

리눅스 커널은 대략 빌드 중이라 늘어난 것일수도 있으니 크게 의미는 없으나 대략 840MB 정도 예상되고

라즈비안에서는 tvservice라는 걸로 해상도는 확인/변경이 가능한데

영구적으로 바뀌는것은 아니고 런타임으로 1회성으로 변경이 가능하며

모니터 특성을 타는지 출력 변경 직후 ctrl-alt-F1 / ctrl-alt-F7을 눌러

다른 터미널로 갔다가 Xwindow로 복귀해야 화면이 제대로 나왔다.


pi@raspberrypi ~ $ sudo tvservice

Usage: tvservice [OPTION]...

  -p, --preferred                   Power on HDMI with preferred settings

  -e, --explicit="GROUP MODE DRIVE" Power on HDMI with explicit GROUP (CEA, DMT, CEA_3D_SBS, CEA_3D_TB)

                                      MODE (see --modes) and DRIVE (HDMI, DVI)

  -t, --ntsc                        Use NTSC frequency for HDMI mode (e.g. 59.94Hz rather than 60Hz)

  -c, --sdtvon="MODE ASPECT"        Power on SDTV with MODE (PAL or NTSC) and ASPECT (4:3 14:9 or 16:9)

  -o, --off                         Power off the display

  -m, --modes=GROUP                 Get supported modes for GROUP (CEA, DMT)

  -M, --monitor                     Monitor HDMI events

  -s, --status                      Get HDMI status

  -a, --audio                       Get supported audio information

  -d, --dumpedid <filename>         Dump EDID information to file

  -j, --json                        Use JSON format for --modes output

  -n, --name                        Print the device ID from EDID

  -h, --help                        Print this information


pi@raspberrypi ~ $ sudo tvservice -p

Powering on HDMI with preferred settings


pi@raspberrypi ~ $ sudo tvservice -modes=CEA

Group CEA has 0 modes:


pi@raspberrypi ~ $ sudo tvservice -modes=DMT

Group DMT has 19 modes:

  (prefer) mode 83: 1600x900 @ 60Hz 16:9, clock:108MHz progressive


pi@raspberrypi ~ $ sudo tvservice -e "DMT 83"

Powering on HDMI with explicit settings (DMT mode 83)


pi@raspberrypi ~ $ sudo tvservice -s

state 0x120016 [DVI DMT (82) RGB full 16:9], 1920x1080 @ 60.00Hz, progressive 


영구적으로 손을 보기 위해서는

config.txt 파일에

#These values are valid if hdmi_group=2 (DMT)

hdmi_group=2

hdmi_mode=82   #1080p      60 Hz  

#hdmi_mode=83   #1600x900          Reduced blanking 

부분을 넣어줘야 한다.

단, 위와 같이 hdmi_group을 지정해 버리면 DVI로만 쓸 수 있고 HDMI로는 안되니 이 것 역시 문제네.. -_-

AVR Studio 5에 연결만 해보고

실행은 제대로 안해봄.. -_-a


Title : USBAsp

Command : avrdude.exe

Arguments : -c usbasp -p atmega16 -B12 -U flash:w:$(ProjectDir)Debug\$(ItemFileName).hex


본인이 사용할 칩에 맞춰서 -p 뒤에 칩을 기재해주면 된다.

GUI 상에는 USBasp는 존재하지 않는다. -_ㅠ

또한 강제로 입력해도 콤보박스로 선택되는거라.. 입력이 되지 않는다.



[링크 : http://sourceforge.net/projects/avrdude-gui/]


이녀석은 싸긴한데..

이걸쓰려면 불편을 감수하고 빌드(AVR Studio) / 플래싱(avrdude.exe) 로 나누어서 해야 할 듯

embeded/AVR (ATmega,ATtiny)2015. 3. 11. 22:03

결론 : AVR studio 4.x 대에서는 기본적으로 호환불가

AVR Studio 5.x 이후에서는 External tools로 avrdude를 연결해서 사용가능 -_-


---

싼거래서 일단 구매하고 해보는데...

생각해보니까 블로그 하는 컴퓨터에는 WinAVR 이나 AVRstudio 가 없잖아? ㅠㅠ

일단 드라이버만 다운로드 받아서 설치!




With WinAVR version 20100110 or older, please use libusb_0.1.12.1

라는 README 파일이 있으니까

버전에 맞추어서

libusb_0.1.12.1 아래에서 깔던가 (WinAVR 2010.01.10 이전 버전)

libusb_1.2.4.0 아래에서 깔면된다.

AVR Studio 4.14 에서 시도해보니.

USB로 되어있는 어떠한 장치도 인식을 하지 못한다 -_-




AVRDUDE를 이용해서 읽어오는 건 된다.

일단.. AVR Studio 5.x 이후 부터 외부 프로그램을 통해 구을수 있으니..

4.X 대에서는 포기해야 할 지도?
