so, ich habe es hin bekommen:
man muss die thread prios unter die von main loop setzen, damit der watch dog von main gefüttert wird.
Da main immer prio=1 by default hat, müssen die threads bei prio 0 laufen, damit sie nicht blockieren können:
Code:// std::thread for ESP32, Arduino IDE // ver 0.0.6 fibonacci #include <Arduino.h> #include <thread> #include <freertos/task.h> #ifndef LED_BUILTIN #define LED_BUILTIN 13 #endif const auto one_sec = std::chrono::seconds { 1 }; uint32_t fibonacci(uint32_t n) { if(n == 0){ return 0; } else if(n == 1) { return 1; } else { return (fibonacci(n-1) + fibonacci(n-2)); } } void blinker_loop() { thread_local uint32_t counter = 0; Serial.println((String)"blinker_loop Current priority :" + uxTaskPriorityGet(NULL)); vTaskPrioritySet(NULL,0);//set Priority Serial.println((String)"blinker_loop Current priority :" + uxTaskPriorityGet(NULL)); while(true) { digitalWrite(LED_BUILTIN, HIGH); Serial.println((String)"blinker_loop (HIGH) counter: "+ counter); std::this_thread::sleep_for(one_sec); digitalWrite(LED_BUILTIN, LOW); Serial.println((String)"blinker_loop (LOW) counter: "+ counter); std::this_thread::sleep_for(one_sec); counter++; } } void fibonacci_loop() { thread_local uint32_t counter = 0, i=0; Serial.println((String)"fibonacci_loop Current priority :" + uxTaskPriorityGet(NULL)); vTaskPrioritySet(NULL,0);//set Priority Serial.println((String)"fibonacci_loop Current priority :" + uxTaskPriorityGet(NULL)); while(true) { for(i=30; i<41; i++) { // limits: test, debug Serial.println( (String)"Fibbonacci of "+i+"="+fibbonacci(i)); } Serial.println((String)"fibonacci_loop counter: "+counter); counter++; } } std::thread *thread_1; std::thread *thread_2; void setup() { Serial.begin(115200); delay(1000); thread_1 = new std::thread(blinker_loop); thread_2 = new std::thread(fibonacci_loop); } void loop() { delay(500); static uint32_t main_loop_counter = 0; Serial.println((String)"main loop: " + main_loop_counter); delay(5000); main_loop_counter++; }
ntl nur der jetzige Stand, möglicherweise erscheinen doch wieder irgendwann neue Erkenntnisse...Code:blinker_loop Current priority :5 blinker_loop Current priority :0 fibonacci_loop Current priority :5 blinker_loop (HIGH) counter: 0 fibonacci_loop Current priority :0 Fibbonacci of 30=832040 main loop: 0 Fibbonacci of 31=1346269 blinker_loop (LOW) counter: 0 Fibbonacci of 32=2178309 blinker_loop (HIGH) counter: 1 Fibbonacci of 33=3524578 blinker_loop (LOW) counter: 1 blinker_loop (HIGH) counter: 2 Fibbonacci of 34=5702887 blinker_loop (LOW) counter: 2 main loop: 1 blinker_loop (HIGH) counter: 3 blinker_loop (LOW) counter: 3 blinker_loop (HIGH) counter: 4 Fibbonacci of 35=9227465 blinker_loop (LOW) counter: 4 blinker_loop (HIGH) counter: 5 blinker_loop (LOW) counter: 5 main loop: 2 blinker_loop (HIGH) counter: 6 blinker_loop (LOW) counter: 6 Fibbonacci of 36=14930352 blinker_loop (HIGH) counter: 7 blinker_loop (LOW) counter: 7 blinker_loop (HIGH) counter: 8 main loop: 3 blinker_loop (LOW) counter: 8 blinker_loop (HIGH) counter: 9 blinker_loop (LOW) counter: 9 blinker_loop (HIGH) counter: 10 blinker_loop (LOW) counter: 10 Fibbonacci of 37=24157817 blinker_loop (HIGH) counter: 11 main loop: 4 blinker_loop (LOW) counter: 11 blinker_loop (HIGH) counter: 12 blinker_loop (LOW) counter: 12 blinker_loop (HIGH) counter: 13 blinker_loop (LOW) counter: 13 main loop: 5 blinker_loop (HIGH) counter: 14 blinker_loop (LOW) counter: 14 blinker_loop (HIGH) counter: 15 blinker_loop (LOW) counter: 15 blinker_loop (HIGH) counter: 16 blinker_loop (LOW) counter: 16 main loop: 6 blinker_loop (HIGH) counter: 17 blinker_loop (LOW) counter: 17 Fibbonacci of 38=39088169 blinker_loop (HIGH) counter: 18 blinker_loop (LOW) counter: 18 blinker_loop (HIGH) counter: 19 main loop: 7 blinker_loop (LOW) counter: 19 blinker_loop (HIGH) counter: 20 blinker_loop (LOW) counter: 20 blinker_loop (HIGH) counter: 21 blinker_loop (LOW) counter: 21 blinker_loop (HIGH) counter: 22 main loop: 8 blinker_loop (LOW) counter: 22 blinker_loop (HIGH) counter: 23 blinker_loop (LOW) counter: 23 blinker_loop (HIGH) counter: 24 blinker_loop (LOW) counter: 24 main loop: 9 blinker_loop (HIGH) counter: 25 blinker_loop (LOW) counter: 25 blinker_loop (HIGH) counter: 26 blinker_loop (LOW) counter: 26 blinker_loop (HIGH) counter: 27 blinker_loop (LOW) counter: 27 main loop: 10 blinker_loop (HIGH) counter: 28 blinker_loop (LOW) counter: 28 blinker_loop (HIGH) counter: 29 Fibbonacci of 39=63245986 blinker_loop (LOW) counter: 29 blinker_loop (HIGH) counter: 30 main loop: 11 blinker_loop (LOW) counter: 30 blinker_loop (HIGH) counter: 31 blinker_loop (LOW) counter: 31 blinker_loop (HIGH) counter: 32 blinker_loop (LOW) counter: 32 blinker_loop (HIGH) counter: 33 main loop: 12 blinker_loop (LOW) counter: 33 blinker_loop (HIGH) counter: 34 blinker_loop (LOW) counter: 34 blinker_loop (HIGH) counter: 35 blinker_loop (LOW) counter: 35 main loop: 13 blinker_loop (HIGH) counter: 36 blinker_loop (LOW) counter: 36 blinker_loop (HIGH) counter: 37 blinker_loop (LOW) counter: 37 blinker_loop (HIGH) counter: 38 blinker_loop (LOW) counter: 38 main loop: 14 blinker_loop (HIGH) counter: 39 blinker_loop (LOW) counter: 39 blinker_loop (HIGH) counter: 40 blinker_loop (LOW) counter: 40 blinker_loop (HIGH) counter: 41 main loop: 15 blinker_loop (LOW) counter: 41 blinker_loop (HIGH) counter: 42 blinker_loop (LOW) counter: 42 blinker_loop (HIGH) counter: 43 blinker_loop (LOW) counter: 43 blinker_loop (HIGH) counter: 44 main loop: 16 blinker_loop (LOW) counter: 44 blinker_loop (HIGH) counter: 45 blinker_loop (LOW) counter: 45 blinker_loop (HIGH) counter: 46 blinker_loop (LOW) counter: 46 main loop: 17 blinker_loop (HIGH) counter: 47 Fibbonacci of 40=102334155 fibonacci_loop counter: 0 Fibbonacci of 30=832040 blinker_loop (LOW) counter: 47 Fibbonacci of 31=1346269 blinker_loop (HIGH) counter: 48 Fibbonacci of 32=2178309 blinker_loop (LOW) counter: 48 Fibbonacci of 33=3524578 blinker_loop (HIGH) counter: 49 blinker_loop (LOW) counter: 49 main loop: 18 Fibbonacci of 34=5702887 blinker_loop (HIGH) counter: 50 blinker_loop (LOW) counter: 50 blinker_loop (HIGH) counter: 51 Fibbonacci of 35=9227465 blinker_loop (LOW) counter: 51 blinker_loop (HIGH) counter: 52 main loop: 19 blinker_loop (LOW) counter: 52 blinker_loop (HIGH) counter: 53 blinker_loop (LOW) counter: 53 blinker_loop (HIGH) counter: 54 Fibbonacci of 36=14930352 blinker_loop (LOW) counter: 54 blinker_loop (HIGH) counter: 55 main loop: 20 blinker_loop (LOW) counter: 55
