HeliOS 0.3.3 seems to can not pass the globe var value to in "blink" example ...

Hi Guys : I am learning how to make a multi-tasks project with HeliOS 0.3.3 ,I make the code as following:

heliOS_learning.zip which is base on HeliOS example "Coop" .I am trying to run 3 tasks in this program 1:blink the LED (base on example "Blink") 2: two task-nobody (just delay(XXX) and print a letter out to serial port

Here is the task function:

void taskShortmain(xTask task, xTaskParm parm_) { int ledState = DEREFTASKPARM(int, parm); Serial.print("led 1 ");Serial.println(ledState); if (ledState) { digitalWrite(LED_BUILTIN, HIGH);

Serial.print("led 2 ");Serial.println(ledState);

ledState = 0;

Serial.print("led 3 ");Serial.println(ledState);

} else { digitalWrite(LED_BUILTIN, LOW);

ledState = 1;

Serial.print("led 4 ");Serial.println(ledState);

} DEREFTASKPARM(int, parm) = ledState; Serial.print("led 5 ");Serial.println(ledState); return; }

And serial print out :

08:38:03.355 -> L 08:38:03.966 -> M 08:38:03.966 -> led 1 0 timeloop1 in-value =0 ,init value ,OK 08:38:03.966 -> led 4 1 timeloop1 change ledstate ,working good 08:38:03.966 -> led 5 1 08:38:04.342 -> L 08:38:04.953 -> M 08:38:05.375 -> L 08:38:05.375 -> led 1 0 timeloop2 in-value =0?,suppose to be 1 ,working not OK now 08:38:05.375 -> led 4 1 timeloop2
08:38:05.375 -> led 5 1

The var Ledstate do changed in Task "taskShort_main" and pass-thought out to DEREFTASKPARM(int, parm) (LED 1 in-value = 0 , LED4 out-value = 1 ),but in the next task Schedule Led1 read in value still is 0 ,suppose to be LED1 = 1 .

so , I make the same coding in example "Blink" , as following :

Blink-check.zip

And serial print out :

08:46:44.589 -> led 1 0 timeloop1 in-value =0 ,init value ,OK 08:46:44.589 -> led 4 1 timeloop1 change ledstate ,working good 08:46:45.625 -> led 1 1 timeloop2 in-value =1 ,from lastloop led4 out-value ,working good
08:46:45.625 -> led 2 1 timeloop2 08:46:45.625 -> led 3 0 timeloop2 change ledstata, output value . 08:46:46.602 -> led 1 0 08:46:46.602 -> led 4 1 08:46:47.653 -> led 1 1 08:46:47.653 -> led 2 1 08:46:47.653 -> led 3 0

the coding is work....

I have tried Arduino Nano , LGT8F328P Nano , both "blink" program running OK , "Coop+Blink" not OK , I also tried D1 mini ,but seems HeliOS 0.3.3 not working good . I can not locate where is "ARDUINO_ARCH_ESP8266" in HeliOS.h.

I am not sure which parts is not OK now ...... Would you Please help me to check it out !!!! Thanks all guys and best wishes !!!

The code needs to be written as follows to pass ledState between tasks

xTask shortTask = xTaskCreate("SHORT", taskShort_main, &ledState); xTask longTask = xTaskCreate("LONG", taskLong_main, &ledState); xTask OLEDTask = xTaskCreate("OLED", taskOLED_main, &ledState);

Also, you should not use delay() in any task. Instead, use a task timer.

Oh!!!! What a simple mistake I have made ........LOL

DO remember double CHECK all parms which are need to passthrough !!!

Thank you so much ! best wishes! @MannyPeterson
