以下是使用C语言编写的Art-Net 3的ArtPollReply开启32个空间的示例程序:
```c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <arpa/inet.h>
typedef struct {
char id[8];
unsigned short opcode;
unsigned int ip;
unsigned short port;
unsigned short versInfo;
unsigned char netSwitch;
unsigned char subSwitch;
unsigned short oem;
unsigned char ubeaVersion;
unsigned char status1;
unsigned short estaMan;
char shortName[18];
char longName[64];
char nodeReport[64];
unsigned short numPorts;
unsigned char portTypes[32]; // 每个端口的类型,最多支持32个端口
unsigned char goodInput[32]; // 每个输入端口的状态,最多支持32个端口
unsigned char goodOutput[32]; // 每个输出端口的状态,最多支持32个端口
unsigned char swIn[32]; // 输入端口的软件设置,最多支持32个端口
unsigned char swOut[32]; // 输出端口的软件设置,最多支持32个端口
unsigned char swVideo;
unsigned char swMacro;
unsigned char swRemote;
unsigned int spare;
} ArtPollReplyPacket;
int main() {
ArtPollReplyPacket reply;
strcpy(reply.id, "Art-Net");
reply.opcode = htons(0x2100);
reply.ip = inet_addr("192.168.1.100");
reply.port = htons(0x1936);
reply.versInfo = htons(0x010e);
reply.netSwitch = 0x00;
reply.subSwitch = 0x00;
reply.oem = htons(0x1234);
reply.ubeaVersion = 0x01;
reply.status1 = 0x00;
reply.estaMan = htons(0x5678);
strcpy(reply.shortName, "Device");
strcpy(reply.longName, "Art-Net Device");
strcpy(reply.nodeReport, "Ready");
reply.numPorts = htons(32);
// 设置32个端口的类型为输出
memset(reply.portTypes, 0x80, sizeof(reply.portTypes));
// 设置32个输入端口状态为正常
memset(reply.goodInput, 0x01, sizeof(reply.goodInput));
// 设置32个输出端口状态为正常
memset(reply.goodOutput, 0x01, sizeof(reply.goodOutput));
// 设置32个输入端口的软件设置
memset(reply.swIn, 0x00, sizeof(reply.swIn));
// 设置32个输出端口的软件设置
memset(reply.swOut, 0x00, sizeof(reply.swOut));
reply.swVideo = 0x00;
reply.swMacro = 0x00;
reply.swRemote = 0x00;
reply.spare = htonl(0x00000000);
int sockfd;
if ((sockfd = socket(AF_INET, SOCK_DGRAM, 0)) < 0) {
perror("socket creation failed");
exit(EXIT_FAILURE);
}
struct sockaddr_in destAddr;
memset(&destAddr, 0, sizeof(destAddr));
destAddr.sin_family = AF_INET;
destAddr.sin_port = htons(0x1936);
destAddr.sin_addr.s_addr = inet_addr("255.255.255.255");
if (sendto(sockfd, &reply, sizeof(reply), 0, (struct sockaddr*)&destAddr, sizeof(destAddr)) < 0) {
perror("sendto failed");
exit(EXIT_FAILURE);
}
close(sockfd);
return 0;
}
```
这个示例程序与之前的示例相似,但在ArtPollReply数据包中添加了对32个空间的支持。在程序中,我们使用了32个字节大小的数组来表示每个端口的类型、输入状态和输出状态,并使用memset函数进行了初始化设置。你可以根据实际需求修改数据包字段的值。
请注意,不是所有的Art-Net设备都支持或实现了32个空间的功能,因此在使用时需要确认设备的兼容性和功能支持。确保遵循Art-Net协议规范以确保与其他设备的兼容性。
