[STM32-48 SSM EVM] STM32F103 Arduino 만들기

Arduino Board 파일은 https://github.com/stm32duino/Arduino_Core_STM32 를 사용한다.

먼저 Arduino 

https://github.com/stm32duino/BoardManagerFiles/raw/main/package_stmicroelectronics_index.json

 

Arduino Boards Manager 에서 Genernic STM32F1 Series를 선택한다.

 

 

Board part number를 ELAB_STM32F1x_SSM 보드를 선택 한다.
Generic F1 보드파일을 수정해서 ELAB_STM32F1x_SSM보드파일로 만들었다.

[STM32F103-48 SSM] 보드의 기본 동작 테스트를 아래 코드로 스위치를 누를때 마다 LED가 깜박이는 것을 확인할 수 있다.

 

#define LED_PIN1        PB0
#define SW_PIN1        PB12


void setup() {
	pinMode(LED_PIN1, OUTPUT);
	pinMode(SW_PIN1, INPUT_PULLUP);

	Serial.begin(115200);
}

int cnt = 0;
int led_toggle = 0;

void loop() {
  
	if(digitalRead(SW_PIN1) == 0)
	{
		led_toggle ^= 1;
		digitalWrite(LED_PIN1, led_toggle);
		
		Serial.println(cnt++);
		delay(500);		
	}
}
