악보 - 보표와 옥타브

도는 도인데

왼손 한옥타브 위는 오른손 가온도 위치이고

악보상에서 왼손에서 내려가면 한 옥타브 낮은 도는 둘째칸에 생긴다.

 

낮은 음자리표 도에서 7개(도시라솔파미레도) 내려가보면 오른쪽이 나온다.

[링크 : https://m.blog.naver.com/piani312/222121550244]

 

 

한 음표만 특정 옥타브로 8va 이렇게 표시해서 보내버릴수도 있고 

8 줄 치고 혹은 8va 줄 쳐서 해당 영역의 옥타브를 같은 악보상에서 표현할 수 있다고 한다.

가온도는 C4 라고 표시되는데(4번째 옥타브, 도)

8va는 올리거나 내리라는 의미라고 하고

실제로 아래 보면 C3 / C1 / C1 이라고 쓰여있는데

가온도가 C4(오른손 도) 에서 한옥타브 래여와서 왼손이 C3 치고 있는데

거기서 하나더 내려오면 C2 인데 8va 붙여서 C1 으로 치게 되나보다..

와.. 어려워 -_-

버튜버 모델 miko vrm

얼핏 보기로는 국제 표준으로 버튜버 모델에 대한게 있다고 하던데 그 샘플인가?

 [링크 : https://miko.aituberonair.com/ko/]

 

음.. 일단 플러그인도 있으니 나중에 시도는 해봐야겠다.

openpty, forkpty, login_tty

gpt 말로는 scanf() 같이 터미널에서 입력 받는 등, pipe 보다는 터미널의 영향을 받는 프로그램을 테스트 하기 좋다고. 

forkpty는 fork + openpty 라는데 한번 둘러는 봐야겠다.

 

The openpty() function finds an available pseudoterminal and returns file descriptors for the master and slave in amaster and aslave. If name is not NULL, the filename of the slave is returned in name. If termp is not NULL, the terminal parameters of the slave will be set to the values in termp. If winp is not NULL, the window size of the slave will be set to the values in winp.
The login_tty() function prepares for a login on the terminal fd (which may be a real terminal device, or the slave of a pseudoterminal as returned by openpty()) by creating a new session, making fd the controlling terminal for the calling process, setting fd to be the standard input, output, and error streams of the current process, and closing fd.

The forkpty() function combines openpty(), fork(2), and login_tty() to create a new process operating in a pseudoterminal. The file descriptor of the master side of the pseudoterminal is returned in amaster, and the filename of the slave in name if it is not NULL. The termp and winp arguments, if not NULL, will determine the terminal attributes and window size of the slave side of the pseudoterminal.

midi tab의 program이 악기라고 한다.

 

[링크 : https://docs.lmms.io/user-manual/production/midi]

 

M100 전자피아노에서는 아래의 번호인데

완전한 General Midi(GM)은 아니지만 어느정도는 비슷하게 배열되어있는둣?

 

건반이 88개 밖에 안되서(?) 88개만 해둔건가?

midi 는 7bit 갯수 만큼 128개 이고?

장치를 잘 인식하면 선택하고

출력이니까 미리 입력해둔 악보를 프로그램 바꾸면

7seg 지시창의 숫자가 바뀌진 않고 음색이 바뀌어서 나온다.

stm32f103c9t6(bluepill) + keypad

귀찮으니 오늘도 대충대충

그나저나 고스팅이란걸 겪어보니 참 난해하구만?

 

핀은 아래처럼 구성하고

 

C1~C4는 A0~A3에 연결함 (C1을 LSB로 보게 하기 위해서)

 

코드는 효율적이진 못하지만 일단 대충 이런느낌으로 작성

row를 high / low로 바꾸면서 col을 읽는구조로 해놨고(col - pin 0~3, row - pin 4~7)

#define BUF_SIZE 50
uint8_t usb_buf[BUF_SIZE];
uint32_t count = 0;
#if 1
int prev_val = 0;
void gpio_proc()
{
  int val = 0;
  // row
  // val |= (HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_4) << 4);
  // val |= (HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_5) << 5);
  // val |= (HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_6) << 6);
  // val |= (HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_7) << 7);

  char *swname[4][4] = {
    {"S1", "S2", "S3", "S4"},
    {"S5", "S6", "S7", "S8"},
    {"S9", "S10", "S11", "S12"},
    {"S13", "S14", "S15", "S16"}
  };

  for(uint16_t row_idx = 0; row_idx < 4; row_idx ++)
  {
    uint16_t pin_arr[] = {GPIO_PIN_4, GPIO_PIN_5, GPIO_PIN_6, GPIO_PIN_7};
    HAL_GPIO_WritePin(GPIOA, pin_arr[row_idx], GPIO_PIN_SET);
    HAL_Delay(1);

    // column
    val |= (HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_0) << 0);
    val |= (HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_1) << 1);
    val |= (HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_2) << 2);
    val |= (HAL_GPIO_ReadPin(GPIOA, GPIO_PIN_3) << 3);

    HAL_GPIO_WritePin(GPIOA, pin_arr[row_idx], GPIO_PIN_RESET);

    int col_idx = 0;
    for(int col_idx = 0; col_idx < 4; col_idx++)
    {
      if((val >> col_idx) & 0x01)
      {
        char *name = swname[row_idx][col_idx];
        sprintf((char*)usb_buf + strlen(usb_buf), "%s ", name);
      }
    }

    val = 0;
  }

  sprintf((char*)usb_buf + strlen(usb_buf), " --- %d %X\r\n", count, val);
  CDC_Transmit_FS(usb_buf, BUF_SIZE);
  memset(usb_buf,0,BUF_SIZE);
  count++;

}
#endif

 

한 행에 누르면 전부 인식되지만 (열은 구분 문제 없음)

 

한 열에 누르면 (S4 + S8 + S12)

해당 라인 자체가 눌리지 않은것으로 나온다. 이래서 다이오드 다는건가?
