L298N 스펙

  1. DC motor 1 "+" or stepper motor A+
  2. DC motor 1 "-" or stepper motor A-
  3. 12V jumper - remove this if using a supply voltage greater than 12V DC. This enables power to the onboard 5V regulator
  4. Connect your motor supply voltage here, maximum of 35V DC. Remove 12V jumper if >12V DC
  5. GND
  6. 5V output if 12V jumper in place, ideal for powering your Arduino (etc)
  7. DC motor 1 enable jumper. Leave this in place when using a stepper motor. Connect to PWM output for DC motor speed control.
  8. IN1
  9. IN2
  10. IN3
  11. IN4
  12. DC motor 2 enable jumper. Leave this in place when using a stepper motor. Connect to PWM output for DC motor speed control.
  13. DC motor 2 "+" or stepper motor B+
  14. DC motor 2 "-" or stepper motor B-

input_ov5640.so

mjpg-streamer의 input_uvc.so는 YUV만 지원하고, BPI-M2 ZERO의 카메라인 OV5640는 YUV420코덱만 지원하기 때문에, mjpg-streamer에서 사용 할 수 없습니다.

제가 작업한 OV5640의 YUV420코덱을 지원하는 so 파일을 공개 합니다.
BPI-M2 ZERO의 카메라인 OV5640를 사용해서 mjpg-streamer로 스트리밍 하시려면 첨부한 파일을 사용하세요.

출처 : GitHub - BPI-SINOVOIP/BPI-WiringPi2: (NEW) support all Banana Pi boards in one version(auto detect)

BPI-WiringPi2 설치

BPI-WiringPi2 소스 다운로드

$ git clone https://github.com/BPI-SINOVOIP/BPI-WiringPi2.git

BPI-WiringPi2 컴파일및 설치

$ cd BPI-WiringPi2
$ chmod +x ./build
$ sudo ./build
 
.. 생략 ...
 
[Install]
 
All Done.
 
NOTE: To compile programs with wiringPi, you need to add:
    -lwiringPi
  to your compile line(s) To use the Gertboard, MaxDetect, etc.
  code (the devLib), you need to also add:
    -lwiringPiDev
  to your compile line(s).
