STM32F103xx IO

STM32F103 시리즈는 최대 72Mhz까지 동작합니다. 그렇다고 모든 기능이 72Mh로 동작하는 것은 아니고, 각 기능마다 약간씩 다릅니다. 그 중에서 I/O 토글링은 18Mhz까지 제어할 수 있습니다.

While 사용

위와 같이 기본값을 설정하고 main 에서 while문으로 PORTE의 4번핀을 토글하게 되면

18Mhz로 동작할거 같은데 실제로는 아래처럼 3.13Mhz 로 파형이 나옵니다.

Optimizations

이는 컴파일 옵션에서 옵티마이즈가 None으로 되어 있어서 그런 겁니다.

아래처럼 옵션에서 High(Speed)로 지정하면 됩니다.

그러면 약 8Mhz까지 나옵니다.

왜 8Mhz 까지만 나올까요?

그것은 while(1) 때문입니다. 아래 2줄을 수행한 후 while문을 검사해야 하기 때문에 8Mhz 이상이 나오지 않는 겁니다.

GPIOE->BSRR = GPIO_Pin_4;
GPIOE->BRR = GPIO_Pin_4;

그렇다면 어떻게 해야 18Mhz 를 얻을 수 있을까요?

While(1)을 사용하지 않으면 될텐데…. While(1)을 사용하지 않는다면 프로그램은 무한히 실행되지 않을 겁니다.

그냥 while(1) 문 안에 무한히 토글해주면 됩니다.

13.0902Mhz

13.4992Mhz

아래처럼 하면 거의 18Mhz에 가까워 집니다.

STM32 Virtual COM Port Driver

다른 칩셋과 마찬가지로 STM32 로 작성된 가상 COM 포트 드라이버를 사용하기 위해서는 별도의 드라이버를 설치해야 합니다.

드라이버가 설치되지 않았다면 아래와 같이 드라이버 인식을 실패합니다.

함께 제공하는 설치정보파일( iarvircomport.inf)로 설치를 시도해도 제대로 인식하지 못할 수 있습니다.

STM32 Virtual COM Port Driver 설치

드라이버 설치파일:

stm32_vcp_win7_64bit..zip

stm32_vcp_xp_32bit..zip

또는 http://www.st.com/internet/mcu/product/164491.jsp 에서 다운 받을 수 있습니다.

압축 파일을 풀면 4개의 파일이 있습니다.

(비스타 또는 7 에서는 필히 압축을 푼후 관리자모드로 설치를 해야 합니다.)

현재 사용중인 OS에 맞는 드라이버를 설치하면 됩니다.

VCP_V1.3.1_Setup.exe: 32비트용 드라이버

VCP_V1.3.1_Setup_x64.exe: 64비트용 드라이버

여기서는 64비트용을 설치해보겠습니다.

그리고, USB 케이블을 다시 연결해도 자동으로 설치되지는 않는다면 수동으로 설치해야 하는데, 아래처럼 직접 경로를 지정하여 처리할 수 있습니다.

경로를 C:\Program Files (x86)\STMicroelectronics\Software\Virtual COM Port Driver 로 지정합니다.

해당 파일에 게시자 정보가 없어 경고가 나타날 수 있습니다.

해당 제품을 사용하려면 당연히 설치해야 합니다.
