How to use

테스트를 하기 위해서는 stm32f103_fw_module → src → main.c 에서 주석을 해제 또는 설정해야 합니다.

#include "main.h"

int main(void)
{
	hwInit();
	apInit();

/* Choose  Test Function */

  	apBoardTest();
//	apUartTest();
//	apGpioTest();
//      apDFPlayerTest();
//	apNRF24L01RxTest();
//	apNRF24L01TxTest();
//      apCLCDTest();
//      apDotMatrixTest();

    return 0;
}

Note

1.

clcd.h와 max7219.h의 #define에서 0x00~0x0f 부분이 중복되어 오류가 발생합니다. 따라서 clcd와 dot matrix는 동시에 테스트할 수 없습니다. 양쪽(clcd & dot matrix)을 동시에 테스트하려면 max7219.h의 #define 0x00 ~0x0f 부분을 static const하게 선언하여 사용해야합니다.

An error occurs due to overlapping parts 0x00~0x0f in #define of clcd.h and max7219.h. Therefore, clcld and dot matrix cannot be tested at the same time. To test both simultaneously (clcd & dot matrix), you must use the static const declaration of #define 0x00 ~ 0x0f (max7219.h).

2.

프로젝트를 빌드할 때는 다음 경로에 있는 폴더를 빌드 및 디버그 항목에서 제외해야 합니다.
When you build a project, you must exclude folders in the following paths from the build and debug entries:

• stm32f411ceu6_fw_module → src → lib → Core

How to exclude

📌

• Click Core folder and proceed with the following steps.

　　　

• The results are as follows.
