本期为大家推送迪文开发者论坛获奖开源案例——AI智能交互新方案：基于T5L的AI DeepSeek大模型。该方案通过T5L串口与AI模块开发板进行数据交互，支持用户与屏幕智能实时对话交互，并同步展示动态表情，构建了具有情感化交互能力的AI终端解决新方案。

（1）屏幕主要程序如下：

#defineMAX_PACKETS 20//预设最大包数量

typedefstruct {

unsigned char *indata;//数据指针

int length;//包长度

} Packet;

int split_packets(constunsigned char *indata, int data_len, Packet *packets, int *packet_count)

{

int positions[MAX_PACKETS] = {0};

int count = 0;

int i;

//查找所有包头位置

for ( i = 0; i <= data_len - 2&& count < MAX_PACKETS; )

{

if (indata == 0x5A &&indata[i+1] == 0xA5) {

positions[count++] = i;

i += 2;//跳过包头

} else {

i++;

}

}

if (count == 0) return -1;

*packet_count = count;

for ( i = 0; i < count; i++) {

int start = positions;

int end = (i < count-1) ?positions[i+1] : data_len;

packets.indata = indata + start;

packets.length = end - start;

}

return 0;

}

#defineOutGbkLen 256

unsignedchar HuanBuffdata[1024];

voidHandleRecData(unsigned char *inputdata,unsigned char len){

char emotions=0;

char emoarr[2];

memset(HuanBuffdata,0,sizeof(HuanBuffdata));

memcpy(HuanBuffdata,inputdata,len);

switch(HuanBuffdata[2]){

case 1://表情

if(HuanBuffdata[3]>20)

emotions=0;

else

emotions=HuanBuffdata[3];

emoarr[0]=0;

emoarr[1]=emotions+1;

write_dgusii_vp(0x3000,emoarr,1);

break;

case 2://网络状态

break;

case 3://通知消息

write_dgusii_vp(0x2000,&HuanBuffdata[3],strlen(&HuanBuffdata[3])/2);

break;

case 4://聊天信息

write_dgusii_vp(0x4000,&HuanBuffdata[3],strlen(&HuanBuffdata[3])/2);

break;

}

}

voidDispDataHandle(void){

int i ;

int data_len = uart4_rx_count;

Packet packets[MAX_PACKETS];//栈内存分配

int packet_count;

if (split_packets(Uart4_Rx, data_len,packets, &packet_count) == 0) {

for ( i = 0; i < packet_count; i++){

HandleRecData(packets.indata,packets.length);

}

}

}

（2）AI模块开发板程序如下：

voidXINGZHI_1_54_TFT_LcdDisplay::SetChatMessage(const char* role, const char* content) {

DisplayLockGuard lock(this);

if(chat_message_label_ == nullptr) {

return;

}

lv_label_set_text(chat_message_label_, content);

char senddata[10];

int i=0;

memset(senddata,0,sizeof(senddata));

senddata[i++]=0x5a;

senddata[i++]=0xa5;

senddata[i++]=0x4;

uart_write_bytes(USART_UX,senddata,i);

uint16_t unicode_string[256];//足够大的缓冲区

memset(unicode_string,0,sizeof(unicode_string));

uint32_tretlen=utf8_to_unicode((const uint8_t*)content,strlen(content),unicode_string);

uint8_t gbk_string[256];//足够大的缓冲区

UnicodeToGbk(unicode_string,gbk_string,sizeof(gbk_string));

uart_write_bytes(USART_UX,gbk_string,strlen((char *)gbk_string));

}

voidXINGZHI_1_54_TFT_LcdDisplay::SetStatus(const char* status) {

DisplayLockGuard lock(this);

if (status_label_ ==nullptr) {

return;

}

lv_label_set_text(status_label_, status);

lv_obj_clear_flag(status_label_, LV_OBJ_FLAG_HIDDEN);

lv_obj_add_flag(notification_label_, LV_OBJ_FLAG_HIDDEN);

char senddata[10];int i=0;

memset(senddata,0,sizeof(senddata));

senddata[i++]=0x5a;

senddata[i++]=0xa5;

senddata[i++]=0x3;

uart_write_bytes(USART_UX,senddata,i);

uint16_t unicode_string[256];//足够大的缓冲区

memset(unicode_string,0,sizeof(unicode_string));

uint32_tretlen=utf8_to_unicode((const uint8_t*)status,strlen(status),unicode_string);

uint8_t gbk_string[256];//足够大的缓冲区

UnicodeToGbk(unicode_string,gbk_string,sizeof(gbk_string));

uart_write_bytes(USART_UX,gbk_string,strlen((char *)gbk_string));

}
