Esp32 ulp arduino. Starting the ULP FSM Program .

Esp32 ulp arduino. I had some ULP code in the Arduino (using ulptool), and noticed that there wasn't any support for ULP in Arduino. For more information, see the Lib Builder documentation . subzero Does the esp-idf ulp stuff work on a linux PC? In general, when using the ULP for GPIO access, you need to be using GPIO pins handled by the RTC GPIO MUX, which are simply GPIOs 0-21 on the S2 family . Periodically I wake up ESP32 to do some stuff. So when it is awake, it will still run the counter on the ULP processor unless you stop the ULP periodic wake up timer, ULP will keep waking up and running while the main CPU is active. I've been using an Arduino Nano ESP32-S3 for a while, and I have had a few problems, but have been able to solve them with little difficulty. Even though the example is for an M5Stack device I think it should be transferable to any ESP32 board. This is not trivial and requires a good understanding of the ESP-IDF build system. Note that the Enable Ultra Low Power (ULP) Coprocessor option must be enabled in menuconfig to work with ULP. I hope you are able to clarify a ESP32 ULP example for Youtube video. 2 posts • Page 1 of 1. i'm trying to implement ulp with rtc-gpio pulse wakeup.
