Allora, ho fatto qualche prova.
il tuo codice Guglielmo non compila
In function 'void setup()':
sketch_jun14b:22: error: 'xTaskCreateStatic' was not declared in this scope
xTaskCreateStatic(MyTask1, "Task1", 192, NULL, 1, uxStackBuffer_T1, &xTaskBuffer_T1);
e non sono riuscito a sistemarlo.
Se invece faccio un ibrido tra i due allora funziona:
questo
#include <Arduino_FreeRTOS.h>
void TaskBlink(void *pvParameters);
void setup() {
pinMode(LED_BUILTIN, OUTPUT);
xTaskCreate(TaskBlink, (const portCHAR *)"Blink", 192, NULL, 1, NULL);
}
void loop() {
// put your main code here, to run repeatedly:
}
void TaskBlink(void *pvParameters) // This is a task.
{
for (;;) // A Task shall never return or exit.
{
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
vTaskDelay(20 / portTICK_PERIOD_MS);
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
vTaskDelay(2000 / portTICK_PERIOD_MS);
}
}
e anche questo
#include <Arduino_FreeRTOS.h>
void TaskBlink(void *pvParameters);
void setup() {
pinMode(LED_BUILTIN, OUTPUT);
xTaskCreate(TaskBlink, (const portCHAR *)"Blink", 128, NULL, 2, NULL);
}
void loop() {
// put your main code here, to run repeatedly:
}
void TaskBlink(void *pvParameters) // This is a task.
{
TickType_t xLastWakeTime;
const TickType_t xPeriod = 2000 / portTICK_PERIOD_MS;
xLastWakeTime = xTaskGetTickCount();
for (;;) // A Task shall never return or exit.
{
vTaskDelayUntil( &xLastWakeTime, xPeriod );
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
vTaskDelay( 20 / portTICK_PERIOD_MS ); // wait for 20millisecond
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
}
}
nel mio codice il problema principale sembra essere pdMS_TO_TICKS() :
p.s. nei reference in pdf, quelli che sto leggendo, portTICK_PERIOD_MS non viene neanche menzionato
