General objective:

• Multitask with the two cores of the ESP32.

Materials:

• TSC-Lab

Introduction:

The ESP-32 has 2 32-bit Xtensa LX6 microprocessors called core 0 and core 1. By default, the code runs on core 1. However, in this laboratory practice, you will learn how to utilize the dual-core of the ESP-32 by performing multitasking, working with both the temperature plant and the motor speed simultaneously.

Steps:

Note: It is assumed that all libraries have been previously installed. 

1- Copy and upload the following code to the TSC-Lab.

2- In the serial monitor, you will see something similar to this:
