[参考译文] SK-AM62：我想在我自己的工程中使用 ti-rpmsg-char

您好、
很抱歉、我忘了提及它。 正在 Linux Processor SDK 上进行开发。 我做了一些挖掘,并找到了一种方法来做到这一点。 您能确认这是否是最好的方法吗

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <fcntl.h>
#include <unistd.h>
#include <errno.h>

#define RPMSG_DEVICE "/dev/rpmsg0"
#define GET_COMMAND "GET_DATA\n"
#define BUFFER_SIZE 128
#define POLL_INTERVAL_SEC 4000  // Delay between requests in microseconds

void rpmsg_poll_loop(void) {
    int fd;
    char buffer[BUFFER_SIZE];
    ssize_t bytes_written, bytes_read;

    // Open RPMsg device
    fd = open(RPMSG_DEVICE, O_RDWR);
    if (fd < 0) {
        perror("Error opening RPMsg device");
        return;
    }

    printf("Starting continuous RPMsg polling...\n");

    while (1) {
        // Send "GET DATA\n" to MCU
        bytes_written = write(fd, GET_COMMAND, strlen(GET_COMMAND));
        if (bytes_written < 0) {
            perror("Error writing to RPMsg device");
            break;
        }

        printf("Sent: %s", GET_COMMAND);

        // Read response from MCU
        bytes_read = read(fd, buffer, BUFFER_SIZE - 1);
        if (bytes_read < 0) {
            perror("Error reading from RPMsg device");
            break;
        }

        buffer[bytes_read] = '\0';  // Null-terminate the string
        printf("Received: %s\n", buffer);

        usleep(POLL_INTERVAL_SEC);  // Wait before next request
    }

    close(fd);
}

谢谢、
Bawantha.
