电阻触摸线序调换顺序和RT-Thread LVGL8诡异问题求助

Sam · 2021-08-20 08:55:08

缘起：
F1C100S 电阻触摸硬件电路电路如图：

而实际的却是：
---->X1;
---->Y1;
---->X2;
---->Y2;
正好中间的X2,Y1顺序调换了位置，导致触摸不正常，一直处于按下状态。查看手册，手册中说明X,Y可以调换，但不知道怎么调，查到的资料贴上来，大家帮忙一起想想办法，多谢大家。

研究了几天触摸线序的问题未果，最终还是乖乖的改了图^^

新问题：
1.在RT-Thread 上移植了 LVGL8，DEMO还没跑成功，悲催:(不知问题出那里了……

	/*GUI初始化*/
	lv_init();
	lv_port_disp_init();
	lv_port_indev_init();
	lv_fs_if_init();	
	while(1)
	{ 
	  lv_task_handler();	
	  rt_thread_mdelay(1);
	}

代码中如果屏蔽 ‘lv_fs_if_init();’，系统可以正常启动，加上则系统跳转失败，串口输出一串乱码

[10:50:54.524]收←◆KQ@|@X`X@Ve4

lv_fs_if_init()代码如下：

void lv_fs_if_init(void)
{
	lv_port_fs_init();
}
void lv_port_fs_init(void)
{
   
    /*----------------------------------------------------
     * Initialize your storage device and File System
     * -------------------------------------------------*/
    fs_init();
    /*---------------------------------------------------
     * Register the file system interface in LVGL
     *--------------------------------------------------*/

    /*Add a simple drive to open images*/
    static lv_fs_drv_t fs_drv;
    lv_fs_drv_init(&fs_drv);

    /*Set up fields...*/
    fs_drv.letter = 'S';
    fs_drv.open_cb = fs_open;
    fs_drv.close_cb = fs_close;
    fs_drv.read_cb = fs_read;
    fs_drv.write_cb = fs_write;
    fs_drv.seek_cb = fs_seek;
    fs_drv.tell_cb = fs_tell;

    fs_drv.dir_close_cb = fs_dir_close;
    fs_drv.dir_open_cb = fs_dir_open;
    fs_drv.dir_read_cb = fs_dir_read;

    lv_fs_drv_register(&fs_drv);
}
static void fs_init(void)
{
    /*E.g. for FatFS initialize the SD card and FatFS itself*/

    /*You code here*/
       /*E.g. for FatFS initalize the SD card and FatFS itself*/
    /*You code here*/
    
    // FATFS * fs = (FATFS*)lv_mem_alloc(sizeof(FATFS));
    FATFS fs;
	FRESULT fres = FR_NOT_READY;


  	if (fres != FR_OK) {
    	fres = f_mount(&fs,"0:",1);
    	if (fres != FR_OK) 
        {
     		SD_Printf("SD Card mounted error. (%d)\n",fres);
    	} 
        else
        {
            SD_Printf("SD Card mounted successfully.\n");
        }
  	}
	// lv_mem_free(fs);
}

界面不显示也就罢了，一旦加入文件系统就启动不了，不知什么问题；
2.接上问题，为了排除是是系统移植有问题，在裸机程序上移植了LVGL，问题更诡异，LVGL启动程序如下：

void Lvgl_start(void)  
{ 
int time1=0;
int time2=0;	
	GPIO_Congif(GPIOE,GPIO_Pin_6,GPIO_Mode_OUT,GPIO_PuPd_NOPULL);
	/*lvgl tick*/	
	Sys_Timer1_Init();
	/*lvgl 初始化*/
	lv_init();
	lv_port_disp_init();
	lv_port_indev_init();
	while(1)
	{ 
		lv_task_handler();	
		delay_us(10);
	}
}

代码中有一行 ‘GPIO_Congif(GPIOE,GPIO_Pin_6,GPIO_Mode_OUT,GPIO_PuPd_NOPULL);’
如果屏蔽，则没办法从boot跳转的应用，如果取消屏蔽则运行正常……
@晕哥真心求助

手册的意思是不是整组交换？

Sam · 2021-09-05 15:17:35

只有一位寄存器，相信也实现不了太多的交换功能，试了一下没什么反应

发个帖子下班：
裸机状态下，总算可以跑起来了,只是'lv_demo_widgets()'的demo 一直不成功；
代码如下：

	/*lvgl tick*/	
	Sys_Timer1_Init();
	/*lvgl 初始化*/
	lv_init();
	lv_port_disp_init();
	lv_port_indev_init();
	// lv_fs_if_init();
// #ifdef RTP_TOUCH_USR	
// 	touch_chCalibrate();/*触屏校正*/
// #endif	
	lv_demo_widgets();
	while(1)
	{ 
		lv_task_handler();	
		delay_us(10);
	}

已经排除了定时器未进入中断问题、延时函数问题，最终定位到了

LV_ATTRIBUTE_TIMER_HANDLER uint32_t lv_timer_handler(void)
{
    TIMER_TRACE("begin");

    /*Avoid concurrent running of the timer handler*/
    static bool already_running = false;

    already_running = true;

    if(lv_timer_run == false) {
        already_running = false; /*Release mutex*/
        TIMER_TRACE("already running, concurrent calls are not allow, returning");
        return 1;
    }

    static uint32_t idle_period_start = 0;
    static uint32_t busy_time         = 0;

    uint32_t handler_start = lv_tick_get();

    if(handler_start == 0) {
        static uint32_t run_cnt = 0;
        run_cnt ++;
        if(run_cnt > 100) {
            run_cnt = 0;
            LV_LOG_WARN("It seems lv_tick_inc() is not called.");
        }
    }
    /*Run all timer from the list*/
    lv_timer_t * next;
    do {
        timer_deleted             = false;
        timer_created             = false;
        LV_GC_ROOT(_lv_timer_act) = _lv_ll_get_head(&LV_GC_ROOT(_lv_timer_ll));
        while(LV_GC_ROOT(_lv_timer_act)) {
            /*The timer might be deleted if it runs only once ('repeat_count = 1')
             *So get next element until the current is surely valid*/
            sysprintf("1\n");
            next = _lv_ll_get_next(&LV_GC_ROOT(_lv_timer_ll), LV_GC_ROOT(_lv_timer_act));
            sysprintf("2\n");
/**

*/
            if(lv_timer_exec(LV_GC_ROOT(_lv_timer_act))) {
                sysprintf("3\n");
                /*If a timer was created or deleted then this or the next item might be corrupted*/
                if(timer_created || timer_deleted) {
                    sysprintf("4\n");
                    TIMER_TRACE("Start from the first timer again because a timer was created or deleted");
                    break;
                }
            }
            sysprintf("5\n");
            LV_GC_ROOT(_lv_timer_act) = next; /*Load the next timer*/
        }
    } while(LV_GC_ROOT(_lv_timer_act));
    uint32_t time_till_next = LV_NO_TIMER_READY;
    next = _lv_ll_get_head(&LV_GC_ROOT(_lv_timer_ll));
    while(next) {
        if(!next->paused) {
            uint32_t delay = lv_timer_time_remaining(next);
            if(delay < time_till_next)
                time_till_next = delay;
        }

        next = _lv_ll_get_next(&LV_GC_ROOT(_lv_timer_ll), next); /*Find the next timer*/
    }

    busy_time += lv_tick_elaps(handler_start);
    uint32_t idle_period_time = lv_tick_elaps(idle_period_start);
    if(idle_period_time >= IDLE_MEAS_PERIOD) {
        idle_last         = (busy_time * 100) / idle_period_time;  /*Calculate the busy percentage*/
        idle_last         = idle_last > 100 ? 0 : 100 - idle_last; /*But we need idle time*/
        busy_time         = 0;
        idle_period_start = lv_tick_get();
    }

    already_running = false; /*Release the mutex*/

    TIMER_TRACE("finished (%d ms until the next timer call)", time_till_next);
    return time_till_next;
}

在执行'lv_timer_exec(LV_GC_ROOT(_lv_timer_act)'时死机引起，具体原因不详，可能是移植哪部分出了问题，明天继续……

跟进一步：
屏蔽了demo例程‘lv_demo_widgets()’，程序执行畅通无阻，继续排查，先上代码

void lv_demo_widgets(void)
{
    if(LV_HOR_RES <= 320) disp_size = DISP_SMALL;
    else if(LV_HOR_RES < 720) disp_size = DISP_MEDIUM;
    else disp_size = DISP_LARGE;

    font_large = LV_FONT_DEFAULT;
    font_normal = LV_FONT_DEFAULT;

    lv_coord_t tab_h;
    if(disp_size == DISP_LARGE) {
        tab_h = 70;
#if LV_FONT_MONTSERRAT_24
        font_large     =  &lv_font_montserrat_24;
#else
        LV_LOG_WARN("LV_FONT_MONTSERRAT_24 is not enabled for the widgets demo. Using LV_FONT_DEFAULT instead.")
#endif
#if LV_FONT_MONTSERRAT_16
        font_normal    =  &lv_font_montserrat_16;
#else
        LV_LOG_WARN("LV_FONT_MONTSERRAT_16 is not enabled for the widgets demo. Using LV_FONT_DEFAULT instead.")
#endif
    } else if(disp_size == DISP_MEDIUM) {
        tab_h = 45;
#if LV_FONT_MONTSERRAT_20
        font_large     =  &lv_font_montserrat_20;
#else
        LV_LOG_WARN("LV_FONT_MONTSERRAT_20 is not enabled for the widgets demo. Using LV_FONT_DEFAULT instead.")
#endif
#if LV_FONT_MONTSERRAT_14
        font_normal    =  &lv_font_montserrat_14;
#else
        LV_LOG_WARN("LV_FONT_MONTSERRAT_14 is not enabled for the widgets demo. Using LV_FONT_DEFAULT instead.")
#endif
    } else { /* disp_size == DISP_SMALL */
        tab_h = 45;
#if LV_FONT_MONTSERRAT_18
        font_large     =  &lv_font_montserrat_18;
#else
    LV_LOG_WARN("LV_FONT_MONTSERRAT_18 is not enabled for the widgets demo. Using LV_FONT_DEFAULT instead.")
#endif
#if LV_FONT_MONTSERRAT_12
        font_normal    =  &lv_font_montserrat_12;
#else
    LV_LOG_WARN("LV_FONT_MONTSERRAT_12 is not enabled for the widgets demo. Using LV_FONT_DEFAULT instead.")
#endif
    }

#if LV_USE_THEME_DEFAULT //LV_PALETTE_LIGHT_GREEN
    lv_theme_default_init(NULL, lv_palette_main(LV_PALETTE_BLUE), lv_palette_main(LV_PALETTE_RED), LV_THEME_DEFAULT_DARK, font_normal);
    // lv_theme_default_init(NULL, lv_palette_main(LV_PALETTE_LIGHT_GREEN), lv_palette_main(LV_PALETTE_LIGHT_GREEN), LV_THEME_DEFAULT_DARK, font_normal);
#endif

    lv_style_init(&style_text_muted);
    lv_style_set_text_opa(&style_text_muted, LV_OPA_50);

    lv_style_init(&style_title);
    lv_style_set_text_font(&style_title, font_large);

    lv_style_init(&style_icon);
    lv_style_set_text_color(&style_icon, lv_theme_get_color_primary(NULL));
    lv_style_set_text_font(&style_icon, font_large);

    lv_style_init(&style_bullet);
    lv_style_set_border_width(&style_bullet, 0);
    lv_style_set_radius(&style_bullet, LV_RADIUS_CIRCLE);

    tv = lv_tabview_create(lv_scr_act(), LV_DIR_TOP, tab_h);

    lv_obj_set_style_text_font(lv_scr_act(), font_normal, 0);

    if(disp_size == DISP_LARGE) {
        lv_obj_t * tab_btns = lv_tabview_get_tab_btns(tv);
        lv_obj_set_style_pad_left(tab_btns, LV_HOR_RES / 2, 0);
        lv_obj_t * logo = lv_img_create(tab_btns);
        LV_IMG_DECLARE(img_lvgl_logo);
        lv_img_set_src(logo, &img_lvgl_logo);
        lv_obj_align(logo, LV_ALIGN_LEFT_MID, -LV_HOR_RES / 2 + 25, 0);

        lv_obj_t * label = lv_label_create(tab_btns);
        lv_obj_add_style(label, &style_title, 0);
        lv_label_set_text(label, "LVGL v8");
        lv_obj_align_to(label, logo, LV_ALIGN_OUT_RIGHT_TOP, 10, 0);

        label = lv_label_create(tab_btns);
        lv_label_set_text(label, "Widgets demo");
        lv_obj_add_style(label, &style_text_muted, 0);
        lv_obj_align_to(label, logo, LV_ALIGN_OUT_RIGHT_BOTTOM, 10, 0);
    }
    lv_obj_t * t1 = lv_tabview_add_tab(tv, "Profile");
    lv_obj_t * t2 = lv_tabview_add_tab(tv, "Analytics");
    lv_obj_t * t3 = lv_tabview_add_tab(tv, "Shop");
   profile_create(t1);
   analytics_create(t2);
   shop_create(t3);
   color_changer_create(tv);
}

最终屏蔽了'color_changer_create(tv)' 死机现象消失，打开则又出现死机；

深深的怀疑是移植的时候遗漏了什么，可又找不到……，还是采用笨办法，继续屏蔽

最终定位到了

    // uint32_t i;
    // for(i = 0; palette[i] != _LV_PALETTE_LAST; i++) {
    //     lv_obj_t * c = lv_btn_create(color_cont);
    //     lv_obj_set_style_bg_color(c, lv_palette_main(palette[i]), 0);
    //     lv_obj_set_style_radius(c, LV_RADIUS_CIRCLE, 0);
    //     lv_obj_set_style_opa(c, LV_OPA_TRANSP, 0);
    //     lv_obj_set_size(c, 20, 20);
    //     lv_obj_add_event_cb(c, color_event_cb, LV_EVENT_ALL, &palette[i]);
    //     lv_obj_clear_flag(c, LV_OBJ_FLAG_SCROLL_ON_FOCUS);
    // }

猜想应该是触摸输入部分移植的有点问题或者什么其他问题，明儿继续……
