if ((semaphoreRes == pdTRUE) && !fifo.isEmpty()) {

res = fifo.remove(msg);

}

return res;

}

In the example application an interrupt (a producer) reads data from the UART devices, and sends the collected data to the processing task (a consumer). My message object contains two things: a message event and some data. The consumer task is expected to switch by the message event:

enum EVENT {UART0, UART1};

typedef struct {

enum EVENT event;

size_t data[32];

int dataSize;

} Message;

In the example below I reuse the memory pool from the previous chapter:

MemoryPool<LockDummy, Message, 3> pool;

Mailbox<Message*, LockDummy> myMailbox("mbx", 3);
