If I replace this with delay(1) or use _getCycleCount() spin delay I do not have a problem. The problem looks like it is in the Arduino delayMicroseconds(100) which I call every 1ms. Resetting start it back up for about 45 seconds.

My Sketch stops executing after about 45 seconds of running my application. I selected ESP32 DEV MODULE in Arduino IDE.Īny suggestions on how to switch to the faster speed? When I wrote a Sketch for the WS2812B and use getCycleCount(void) for timing cycles it looks like the ESP32 is running at 160MHz instead of 240MHz that is in the default in the Espressif's esp-idf GitHub repository. I can down load blink and other Sketches. I have the ESP32 Thing and got it working in Arduino IDE. Additionally, the board includes a handful of LEDs and buttons to aid in your development. It also features a LiPo charger, so your ESP32 project can be battery-powered and truly wireless. In addition to the WiFi SoC, the Thing includes an FTDI FT231x, which converts USB to serial, and allows your computer to program and communicate with the microcontroller. The SparkFun ESP32 Thing equips the ESP32 with everything necessary to program, run and develop on the wonderchip. You can even program the Thing through the Arduino IDE by installing the ESP32 Arduino Core. The Thing does everything from turning on an LED to posting data with your chosen platform, and can be programmed just like any microcontroller. Why the name? We lovingly call it the “Thing” because it's the perfect foundation for your Internet of Things project. The ESP32’s power and versatility will make it the foundation of IoT and connected projects for many years to come. Like the 8266, the ESP32 is a WiFi-compatible microcontroller but adds nearly 30 I/O pins. The SparkFun ESP32 Thing is a comprehensive development platform for Espressif’s ESP32, their super-charged version of the popular ESP8266.
