Freertos audio

Using FreeRTOS, create two separate tasks. One listens for input over UART (from the Serial Monitor). Upon receiving a newline character ('\n'), the task allocates a new section of heap memory (using pvPortMalloc ()) and stores the string up to the newline character in that section of heap. It then notifies the second task that a message is.

The FreeRTOS OS that comes with ESP-IDF is capable of multi-core preemptive scheduling, allowing for an intuitive way of writing software. The downside of the ease of programming is that debugging without the right tools is harder: figuring out a bug that is caused by two threads, running even simultaneously on two different CPU cores, can take.

ESP-IDF applications use the common computer architecture patterns of stack (dynamic memory allocated by program control flow) and heap (dynamic memory allocated by function calls), as well as statically allocated memory (allocated at compile time). Because ESP-IDF is a multi-threaded RTOS environment, each RTOS task has its own stack.
