——來自迪文開發(fā)者論壇

本期為大家推送的論壇獲獎開源案例可用于建筑行業(yè)檢測水泥成分含量——基于T5L的水泥多量測定儀。工程師基于T5L智能屏來控制電子重量檢測模塊、測溫模塊、加熱模塊、水分傳感器、攪拌模塊，實(shí)現(xiàn)了固溶和液溶水泥成分含量檢測功能，并支持速率實(shí)時顯示、溫度設(shè)置、歷史記錄、階段參數(shù)設(shè)定等功能。

工程師采用T5L串口2與控制板通訊的初始化命令程序如下：

void app_init()

{

    is_testing = 0;

    test_run_time = 0;

    is_sec = 0;

    period1 = 0;

    is_period1 = 0;

    uart2_init(115200);

    send_bytes("AT+INIT=0\r\n",sizeof("AT+INIT=0\r\n")-1);

    sys_delay_ms(2500);

    sys_pic(1);

    send_bytes("AT+START\r\n",sizeof("AT+START\r\n")-1);

}

T5L智能屏與控制板交互實(shí)現(xiàn)水泥成分檢測功能的主要程序如下：

void btn_click_handler()

{

    #define  BTN_VAL_ADDR  0x1000

    u16 btn_val;

    if(is_testing&&is_sec)

    {

        is_sec = 0;

        test_run_time++;

        btn_val = sprintf(commbuff,"%02u:%02u",(u16)(test_run_time/60),(u16)(test_run_time%60));

        commbuff[btn_val+1] = 0;

        sys_write_vp(TEST_TIME_VP,commbuff,5);

        if(uart2rxsta&UART2_PACKET_OK)

        {

            if(uart2buf[0]==0x01&&uart2buf[1]==0x02)

            {

                init_weight = *(float*)(uart2buf+2);

                init_weight *= (*(float*)flashdat);

                sys_write_vp(0x1178, (u8*)&init_weight, 2);

            }else if(uart2buf[0]==0x02&&uart2buf[1]==0x05)

            {

                init_ml = *(float*)(uart2buf+2);

                init_ml /= (*(float*)flashdat+20);

                sys_write_vp(0x1180, (u8*)&init_ml, 2);

            }else if(uart2buf[0]==0x03&&uart2buf[1]==0x07)

            {

                speed_val = *(float*)(uart2buf+2);

                disp_val += (speed_val*2.45f);

                sys_write_vp(0x1180, (u8*)&disp_val, 2);

            }else if(uart2buf[0]==0x04)

            {

                total_num = uart2buf[1]*256+uart2buf[2];

            }else if(uart2buf[0]==0x05)

            {

                is_en_tmp = uart2buf[2];

            }

            uart2rxsta = 0;

        }

    }

    if(is_period1)

    {

        is_period1 = 0;

        t_sample();

        if(is_testing&&is_en_tmp)

            sys_write_vp(0x1170,(u8*)&tmp,2);

    }

    if(is_btn_scan==0)

        return;

    is_btn_scan = 0;

    sys_read_vp(BTN_VAL_ADDR,(u8*)&btn_val,1);

    if(btn_val==0)

        return;

    if(btn_val<=0x10)

        start_win_btn_click_handler(btn_val);

    btn_val = 0;

    sys_write_vp(BTN_VAL_ADDR,(u8*)&btn_val,1);

}
