4. CherryRB

4.1. Overview

The cherryrb sample project demonstrates basic read/write operations using the CherryRB ring buffer.
Implements the producer-consumer pattern in a multi-threaded environment.

4.2. Functional Description

Core functionality: Asynchronous data transfer between two FreeRTOS threads via ring buffer
Producer thread: Writes “hello world” string to the ring buffer every second
Consumer thread: Reads data from the ring buffer every second and prints to UART

4.3. Hardware Setup

No special hardware configuration required

4.4. Runtime Behavior

When the program runs correctly, the UART terminal will display FIFO operations:

chry_ringbuffer_init success
[P] write success
[C] read success, read 11 byte
hello world
[P] write success
[C] read success, read 11 byte
hello world
[P] write success
[C] read success, read 11 byte
hello world
[P] write success
[C] read success, read 11 byte
hello world
[P] write success
[C] read success, read 11 byte
hello world
[P] write success
[C] read success, read 11 byte
hello world
[P] write success
[C] read success, read 11 byte
