Piyush Shah 332c6e7d58 examples: Increase FreeRTOS timer stack size

Button event callbacks are executed in the context of FreeRTOS Timer task.
Reporting param updates from that causes stack overflow, specifically on ESP32-C3.
As a temporary workaround, the stack size for FreeRTOS Timer task has been increased.

Temperature Sensor Example

Build and Flash firmware

Follow the ESP RainMaker Documentation Get Started section to build and flash this firmware. Just note the path of this example.

What to expect in this example?

This example uses esp timer and the RGB LED on the ESP32-S2-Saola-1/ESP32-C3-DevKitC board to demonstrate a temperature sensor.
The temperature value is changed by 0.5 every minute.
It starts at some default value (25.0) and goes on increasing till 99.5. Then it starts reducing till it comes to 0.5. The cycle keeps repeating.
The LED color indicates the temperature.
LED hue changes from 200 (bluish) to 0 (reddish) as the temperature increases from 0.5 to 99.5.
You can check the temperature changes in the phone app.

LED not working?

The ESP32-S2-Saola-1 board has the RGB LED connected to GPIO 18. However, a few earlier boards may have it on GPIO 17. Please use CONFIG_WS2812_LED_GPIO to set the appropriate value.

Reset to Factory

Press and hold the BOOT button for more than 3 seconds to reset the board to factory defaults. You will have to provision the board again to use it.
