本期為大家推送的論壇獲獎(jiǎng)開(kāi)源案例可用于建筑行業(yè)檢測(cè)水泥成分含量——基于T5L智能屏的水泥多量測(cè)定儀。工程師基于T5L智能屏來(lái)控制電子重量檢測(cè)模塊、測(cè)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(cè)功能，并支持速率實(shí)時(shí)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(cè)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);
