Multicore programming with Spresense using the Arduino IDE
The Spresense development board is unique in the sense that it supports multicore programming using the Arduino IDE. Spresense is powered by 6 Arm cores running at 156 MHz, which is many times faster than most Arduino boards. Once you have set up your Arduino IDE for Spresense, there are two simple step-by-step tutorial examples that explain how to do multicore programming using the Arduino IDE:
For additional details on multicore programming using the Arduino IDE, there is a dedicated chapter in the Spresense Arduino IDE developer guide called "MultiCore MP Library".
