Chapter 3: Impressive Outputs with Displays
Some IoT products require an immediate visual output to end users; for example, a smart thermostat needs to have a display to show setpoints.

Another subject that we are going to learn is FreeRTOS, which is the official RTOS supported by ESP32. In actual fact, we have already used several FreeRTOS functions in the examples, but there is more to learn with a view to developing real-world products.
In this chapter, we're going to cover the following main topics:
- Using LCDs
- Interfacing with OLED displays
- TFT displays for superior graphics
- Using FreeRTOS ...
