I am moving from ESP8266 NONOS SDK to ESP32 with Arduino and learning it slowly. I am trying to create 2 tasks running in parallel. Tasks gets created execute first loop and then ESP crashes. I am attaching my simple code and Crash logs. Can someone please let me know what is wrong with the below code causing ESP crash and reboot.
Here is the code
Code: Select all
/*
Task
*/
#include <Arduino.h>
void writeTask(void *parameter);
void readTask(void *parameter);
void setup() {
Serial.begin(115200);
xTaskCreate(
writeTask, // Function name of the task
"Write Count", // Name of the task (e.g. for debugging)
2048, // Stack size (bytes)
NULL, // Parameter to pass
1, // Task priority
NULL // Task handle
);
xTaskCreate(
readTask, // Function name of the task
"Read Count", // Name of the task (e.g. for debugging)
2048, // Stack size (bytes)
NULL, // Parameter to pass
1, // Task priority
NULL // Task handle
);
}
void writeTask(void *parameter) {
int i;
for (i=0; i<100; i++);
{
Serial.print("Writing Task\r\n");
delay(1000);
}
}
void readTask(void *parameter) {
int i;
for (i=0; i<100; i++);
{
Serial.print("Read Task\r\n");
delay(1000);
}
}
void loop() {
}
