Hi,
I try to simulate the FreeRTOS programs using proteus. In my program i have 2 tasks. both task will display message in the terminal. the problem is only one task is running, even though i have given the vTaskDelay(5) in both the tasks only the higher priority task is always running. The low priority task is not running.
i put the screen shot of my simulation and corresponding program plz help me

Code:
#include <Arduino_FreeRTOS.h>
// define two tasks for Blink & AnalogRead
void TaskBlink( void *pvParameters );
void TaskAnalogRead( void *pvParameters );
// the setup function runs once when you press reset or power the board
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB, on LEONARDO, MICRO, YUN, and other 32u4 based boards.
}
// Now set up two tasks to run independently.
xTaskCreate(
TaskBlink
, (const portCHAR *)"Blink" // A name just for humans
, 128 // This stack size can be checked & adjusted by reading the Stack Highwater
, NULL
, 1 // Priority, with 3 (configMAX_PRIORITIES - 1) being the highest, and 0 being the lowest.
, NULL );
xTaskCreate(
TaskAnalogRead
, (const portCHAR *) "AnalogRead"
, 128 // Stack size
, NULL
, 2 // Priority
, NULL );
// Now the task scheduler, which takes over control of scheduling individual tasks, is automatically started.
}
void loop()
{
// Empty. Things are done in Tasks.
}

Blink
Turns on an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, LEONARDO, MEGA, and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN takes care
of use the correct LED pin whatever is the board used.
The MICRO does not have a LED_BUILTIN available. For the MICRO board please substitute
the LED_BUILTIN definition with either LED_BUILTIN_RX or LED_BUILTIN_TX.
e.g. pinMode(LED_BUILTIN_RX, OUTPUT); etc.
If you want to know what pin the on-board LED is connected to on your Arduino model, check
the Technical Specs of your board at https://www.arduino.cc/en/Main/Products

Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.
