现在V5，V6和V7都已经统一，而且都是修改同样的函数实现, 包括电阻触摸和电容触摸。
1、裸机无需任何修改，emWin仅需对bsp_ts_touch.c文件函数TOUCH_PutKey做个修改：
[C] 纯文本查看 复制代码 GUI_PID_STATE State;
void TOUCH_PutKey(uint8_t _ucEvent, uint16_t _usX, uint16_t _usY)
{
#if 1
uint16_t xx, yy;
if (g_tTP.Enable == 1) /* 电阻屏。 形参是ADC值 */
{
xx = TOUCH_TransX(_usX, _usY);
yy = TOUCH_TransY(_usX, _usY);
}
else /* GT811，FTX06，GT911 电容触摸走此分之 */
{
/* 无需转换， 直接是坐标值 */
xx = _usX;
yy = _usY;
}
/* 按下, 移动和松手事件 */
switch (_ucEvent)
{
case TOUCH_DOWN:
State.x = xx;
State.y = yy;
State.Pressed = 1;
GUI_PID_StoreState(&State);
break;
case TOUCH_MOVE:
State.x = xx;
State.y = yy;
State.Pressed = 1;
GUI_PID_StoreState(&State);
break;
case TOUCH_RELEASE:
State.Pressed = 0;
GUI_PID_StoreState(&State);
break;
default:
break;
}
#else
uint16_t xx, yy;
uint16_t x = 0, y = 0;
g_tTP.Event[g_tTP.Write] = _ucEvent;
if (g_tTP.Enable == 1) /* 电阻屏。 形参是ADC值 */
{
xx = TOUCH_TransX(_usX, _usY);
yy = TOUCH_TransY(_usX, _usY);
}
else /* GT811，FTX06，GT911 电容触摸走此分之 */
{
/* 无需转换， 直接是坐标值 */
xx = _usX;
yy = _usY;
}
/* 横屏和竖屏方向识别 */
switch (g_tTPParam.TouchDirection)
{
case 0: /* 校准触摸时，屏幕方向为0 */
if (g_LcdDirection == 0) /* 横屏 */
{
x = xx;
y = yy;
}
else if (g_LcdDirection == 1) /* 横屏180°*/
{
x = g_LcdWidth - xx - 1;
y = g_LcdHeight - yy - 1;
}
else if (g_LcdDirection == 2) /* 竖屏 */
{
y = xx;
x = g_LcdWidth - yy - 1;
}
else if (g_LcdDirection == 3) /* 竖屏180° */
{
y = g_LcdHeight - xx - 1;
x = yy;
}
break;
case 1: /* 校准触摸时，屏幕方向为1 */
if (g_LcdDirection == 0) /* 横屏 */
{
x = g_LcdWidth - xx - 1;
y = g_LcdHeight - yy - 1;
}
else if (g_LcdDirection == 1) /* 横屏180°*/
{
x = xx;
y = yy;
}
else if (g_LcdDirection == 2) /* 竖屏 */
{
y = g_LcdHeight - xx - 1;
x = yy;
}
else if (g_LcdDirection == 3) /* 竖屏180° */
{
y = xx;
x = g_LcdWidth - yy - 1;
}
break;
case 2: /* 校准触摸时，屏幕方向为2 */
if (g_LcdDirection == 0) /* 横屏 */
{
y = xx;
x = g_LcdWidth - yy - 1;
}
else if (g_LcdDirection == 1) /* 横屏180°*/
{
y = g_LcdHeight - xx - 1;
x = yy;
}
else if (g_LcdDirection == 2) /* 竖屏 */
{
x = xx;
y = yy;
}
else if (g_LcdDirection == 3) /* 竖屏180° */
{
x = g_LcdWidth - xx - 1;
y = g_LcdHeight - yy - 1;
}
break;
case 3: /* 校准触摸时，屏幕方向为3 */
if (g_LcdDirection == 0) /* 横屏 */
{
y = xx;
x = g_LcdWidth - yy - 1;
}
else if (g_LcdDirection == 1) /* 横屏180°*/
{
y = g_LcdHeight - xx - 1;
x = yy;
}
else if (g_LcdDirection == 2) /* 竖屏 */
{
x = g_LcdWidth - xx - 1;
y = g_LcdHeight - yy - 1;
}
else if (g_LcdDirection == 3) /* 竖屏180° */
{
x = xx;
y = yy;
}
break;
default:
g_tTPParam.TouchDirection = 0; /* 方向参数无效时，纠正为缺省的横屏 */
break;
}
g_tTP.XBuf[g_tTP.Write] = x;
g_tTP.YBuf[g_tTP.Write] = y;
if (++g_tTP.Write >= TOUCH_FIFO_SIZE)
{
g_tTP.Write = 0;
}
/* 调试语句，打印adc和坐标 */
touch_printf("%d - (%d, %d) adcX=%d,adcY=%d\r\n", _ucEvent, x, y, g_tTP.usAdcNowX, g_tTP.usAdcNowY);
#endif
}
2、同样，ThreadX GUIX也仅需对bsp_ts_touch.c文件函数TOUCH_PutKey做个修改：
[C] 纯文本查看 复制代码 #include "gx_api.h"
void TOUCH_PutKey(uint8_t _ucEvent, uint16_t _usX, uint16_t _usY)
{
#if 1
uint16_t xx, yy;
GX_EVENT event;
if (g_tTP.Enable == 1) /* 电阻屏。 形参是ADC值 */
{
xx = TOUCH_TransX(_usX, _usY);
yy = TOUCH_TransY(_usX, _usY);
}
else /* GT811，FTX06，GT911 电容触摸走此分之 */
{
/* 无需转换， 直接是坐标值 */
xx = _usX;
yy = _usY;
}
/* 按下, 移动和松手事件 */
switch (_ucEvent)
{
case TOUCH_DOWN:
event.gx_event_type = GX_EVENT_PEN_DOWN;
event.gx_event_payload.gx_event_pointdata.gx_point_x = xx;

gx_system_event_send(&event);
break;

gx_system_event_fold(&event);
break;
case TOUCH_RELEASE:
event.gx_event_type = GX_EVENT_PEN_UP;

event.gx_event_payload.gx_event_pointdata.gx_point_y = yy;
event.gx_event_sender = 0;
event.gx_event_target = 0;
event.gx_event_display_handle = 0xC0000000;
gx_system_event_send(&event);
break;
default:
break;
}
#else
uint16_t xx, yy;
uint16_t x = 0, y = 0;
g_tTP.Event[g_tTP.Write] = _ucEvent;
if (g_tTP.Enable == 1) /* 电阻屏。 形参是ADC值 */
{
xx = TOUCH_TransX(_usX, _usY);
yy = TOUCH_TransY(_usX, _usY);
}
else /* GT811，FTX06，GT911 电容触摸走此分之 */
{
/* 无需转换， 直接是坐标值 */

yy = _usY;
}
/* 横屏和竖屏方向识别 */
switch (g_tTPParam.TouchDirection)
{
case 0: /* 校准触摸时，屏幕方向为0 */
if (g_LcdDirection == 0) /* 横屏 */
{
x = xx;
y = yy;
}
else if (g_LcdDirection == 1) /* 横屏180°*/
{
x = g_LcdWidth - xx - 1;
y = g_LcdHeight - yy - 1;
}
else if (g_LcdDirection == 2) /* 竖屏 */
{
y = xx;
x = g_LcdWidth - yy - 1;
}
else if (g_LcdDirection == 3) /* 竖屏180° */
{

}
break;

}
else if (g_LcdDirection == 1) /* 横屏180°*/
{

y = yy;
}
else if (g_LcdDirection == 2) /* 竖屏 */
{
y = g_LcdHeight - xx - 1;
x = yy;
}
else if (g_LcdDirection == 3) /* 竖屏180° */
{
y = xx;
x = g_LcdWidth - yy - 1;
}
break;
case 2: /* 校准触摸时，屏幕方向为2 */
if (g_LcdDirection == 0) /* 横屏 */
{
y = xx;
x = g_LcdWidth - yy - 1;
}
else if (g_LcdDirection == 1) /* 横屏180°*/
{
y = g_LcdHeight - xx - 1;
x = yy;
}
else if (g_LcdDirection == 2) /* 竖屏 */
{
x = xx;
y = yy;
}
else if (g_LcdDirection == 3) /* 竖屏180° */
{

/* 调试语句，打印adc和坐标 */
touch_printf("%d - (%d, %d) adcX=%d,adcY=%d\r\n", _ucEvent, x, y, g_tTP.usAdcNowX, g_tTP.usAdcNowY);
#endif
}
3、LVGL无需任何修改，仅需给接口函数touchpad_read提供反馈
[C] 纯文本查看 复制代码 /*Will be called by the library to read the touchpad*/
static void touchpad_read(lv_indev_drv_t * indev_drv, lv_indev_data_t * data)
{
static lv_coord_t last_x = 0;
static lv_coord_t last_y = 0;
uint8_t ret;
int16_t x,y;
ret = TOUCH_GetKey(&x, &y);
/*Save the pressed coordinates and the state*/
if((ret == TOUCH_MOVE)||(ret == TOUCH_DOWN))
{
last_x = x;
last_y = y;
data->state = LV_INDEV_STATE_PR;
}
else //if(ret == TOUCH_RELEASE)
{
data->state = LV_INDEV_STATE_REL;
}
/*Set the last pressed coordinates*/
data->point.x = last_x;
data->point.y = last_y;
}
