WebJul 1, 2013 · 15. The short answer is to declare your variable with the const keyword. If your MCU actually remembers the value of your const variable (i.e. your sine computation actually works), it pretty much has to be stored in flash memory, otherwise it would be lost at the first reboot after programming. The long answer has to do with linker script. WebESP32 Flash Memory Example (Arduino IDE) In this example, we’ll test the Flash memory by saving the last LED state. The LED is toggled by a push button, and whenever its state changes, the last state will be saved to the Flash. We’ll reset the ESP32 board and it should retrieve the last saved state from the Flash memory at startup.
