vistaでstm32duino その19

概要

vistaでstm32duinoやってみた。
freertos、やってみた。

サンプルコード

# include "STM32FreeRTOS.h"

const uint8_t LED_PIN = LED_BUILTIN;
volatile uint32_t count = 0;
TaskHandle_t blink;

static void vLEDFlashTask(void * pvParameters) {
	pinMode(LED_PIN, OUTPUT);
	for (;;) 
	{
		digitalWrite(LED_PIN, HIGH);
		vTaskDelay((50L * configTICK_RATE_HZ) / 1000L);
		digitalWrite(LED_PIN, LOW);
		vTaskDelay((150L * configTICK_RATE_HZ) / 1000L);
	}
}
static void vPrintTask(void * pvParameters) {
	while (1)  
	{
		vTaskDelay(configTICK_RATE_HZ);
		Serial.print(F("Count: "));
		Serial.print(count);
		Serial.print(F(", Unused Stack: "));
		Serial.print(uxTaskGetStackHighWaterMark(blink));
		Serial.print(' ');
		Serial.print(uxTaskGetStackHighWaterMark(0));
		Serial.print(' ');
		Serial.println(uxTaskGetStackHighWaterMark(xTaskGetIdleTaskHandle()));
		count = 0;
	}
}
void setup() {
	Serial.begin(9600);
	while(!Serial) {}
	xTaskCreate(vLEDFlashTask, "Task1", configMINIMAL_STACK_SIZE + 50, NULL, tskIDLE_PRIORITY + 2, &blink);
	xTaskCreate(vPrintTask, "Task2", configMINIMAL_STACK_SIZE + 100, NULL, tskIDLE_PRIORITY + 1, NULL);
	vTaskStartScheduler();
	Serial.println(F("Die"));
	while(1);
}
void loop() {
	while(1) 
	{
		noInterrupts();
		count++;
		interrupts();
	}
}

結果

Count: 9307985, Unused Stack: 163 194 108
