nRF52832 is a popular System-on-Chip (SoC) developed by Nordic Semiconductor. It is commonly used in Bluetooth Low Energy (BLE) applications and supports various wireless protocols. However, it does not have a built-in queue data structure.
To implement a queue using nRF52832, you can use the available data structures in the Nordic SDK, such as lists or arrays, to create your own queue functionality. Here's a simple example of implementing a queue using an array:
```C
#define QUEUE_SIZE 10
typedef struct {
uint8_t items[QUEUE_SIZE];
uint8_t front;
uint8_t rear;
} Queue;
void enqueue(Queue* q, uint8_t item) {
if ((q->rear + 1) % QUEUE_SIZE == q->front) {
// Queue is full
return;
}
q->items[q->rear] = item;
q->rear = (q->rear + 1) % QUEUE_SIZE;
}
uint8_t dequeue(Queue* q) {
if (q->front == q->rear) {
// Queue is empty
return 0;
}
uint8_t item = q->items[q->front];
q->front = (q->front + 1) % QUEUE_SIZE;
return item;
}
void initQueue(Queue* q) {
q->front = 0;
q->rear = 0;
}
int main() {
Queue myQueue;
initQueue(&myQueue);
enqueue(&myQueue, 1);
enqueue(&myQueue, 2);
uint8_t item1 = dequeue(&myQueue); // item1 = 1
uint8_t item2 = dequeue(&myQueue); // item2 = 2
return 0;
}
```
In this example, the `Queue` structure holds an array of items, along with front and rear pointers. The `enqueue` function adds an item to the rear of the queue, and the `dequeue` function removes an item from the front of the queue. The `initQueue` function initializes the queue.
You can modify this implementation based on your specific requirements, such as changing the data type or adding additional functionalities.
