프로젝트 부품

아두이노에서, “Additional boards manager URLs:” 필드에 다음 링크를 사용하여 STM32 지원을 추가합니다.

https://github.com/stm32duino/BoardManagerFiles/raw/master/STM32/package_stm_index.json

아두이노 Library Manager를 통해 다음 라이브러리를 추가합니다:

다음 라이브러리 종속 항목(library dependency) 설치를 승인합니다:

Lab1

STM32H746을 USB 커넥터(CN1)를 통해 PC에 연결하고 아두이노의 Blink 예제를 활용하여 보드를 프로그래밍할 수 있는지 확인합니다. 이 코드는 LD1을 깜박일 것입니다.

void setup() {
  // initialize digital pin LED_BUILTIN as an output
  pinMode(LED_BUILTIN, OUTPUT);
};

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);
  delay(500);
  digitalWrite(LED_BUILTIN, LOW);
  delay(500);
}

전체 소스:

eewiki/machinechat/blob/master/STM32F746_DEVCON_2020/Lab1/Lab1.ino

void setup() {
  // initialize digital pin LED_BUILTIN as an output
  pinMode(LED_BUILTIN, OUTPUT);
};

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);
  delay(500);
  digitalWrite(LED_BUILTIN, LOW);
  delay(500);
}

검증 및 업로드:
LD1이 깜박여야 합니다.

Lab2

STM32H746에는 STM32Ethernet 라이브러리를 통해 활성화 할 수 있는 온보드 이더넷이 있습니다. Ethernet.begin()으로 이 라이브러리를 초기화한 다음 Ethernet.localIP()를 사용하여 새 IP 주소를 디버그 터미널에 프린트합니다. 이 예제에서 IP 주소는 로컬 DHCP 서버로부터 얻어야 합니다.

LwIP.h와 STM32Ethernet.h 헤더 파일을 추가합니다:

#include <LwIP.h>
#include <STM32Ethernet.h>

디버깅을 위해 직렬 포트를 활성화합니다:

  // Open serial communications and wait for port to open:
  Serial.begin(115200);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }

이더넷 라이브러리를 초기화합니다.

  // give the ethernet module time to boot up:
  delay(1000);

  // start the Ethernet connection:
  Ethernet.begin();

  // print the Ethernet board/shield's IP address:
  Serial.print("My IP address: ");
  Serial.println(Ethernet.localIP());

다음으로, Ethernet.linkStatus()를 사용하여 활성 링크가 있는지 확인합니다. LED는 연결이 활성화 되어야만 켜질 것입니다. 이더넷 케이블을 제거하여 시험합니다.

void loop() {
  if (Ethernet.linkStatus() == LinkON) {
    Serial.println("Link status: On");

    digitalWrite(LED_BUILTIN, HIGH);
  }
  else if (Ethernet.linkStatus() == LinkOFF) {
    Serial.println("Link status: Off");

    digitalWrite(LED_BUILTIN, LOW);
  } 
  delay(500);
