• Hands-on FreeRTOS with STM32 NUCLEO-F303ZE
• Implemented FreeRTOS to solve the producer-consumer problem & readers-writers problem with semaphores, mutexes, & volatiles
• Coped with volatile / xSemaphoreCreateMutex() / xSemaphoreGive() / xSemaphoreTake() / xSemaphoreCreateCounting()

(0) Warm-Up

• 0-1 main_01.c: Multithreading with 2 LED light bulbs

(1) Producer-Consumer Problem

• 1-1 main_02.c: With a 1-byte buffer using 2 LED light bulbs
• 1-2 main_03.c: With a 5-byte buffer using 2 LED light bulbs

(2) Readers-Writers Problem

• 2-1 main_04_failed.c: Used 3 LED light bulbs, 2 for the readers and 1 for the writer. Failed for a deadlock between the readers.
• 2-2 main_05.c: Used 3 LED light bulbs, 2 for the readers and 1 for the writer. Solved the preceding deadlock by a semaphore.
