|

|
||
## 最小实现代码
|
||
```python
|
||
from maix import touchscreen
|
||
|
||
ts = touchscreen.TouchScreen()
|
||
x, y, pressed = ts.read()
|
||
```
|
||
|
||
## 样例程序
|
||
|
||
```python
|
||
from maix import touchscreen, app, time, display, image
|
||
|
||
ts = touchscreen.TouchScreen()
|
||
disp = display.Display()
|
||
|
||
img = image.Image(disp.width(), disp.height())
|
||
|
||
def menu_update(img):
|
||
img.draw_string(8, 12, "< Exit", image.COLOR_WHITE)
|
||
img.draw_rect(0, 0, 100, 100, image.COLOR_WHITE, 2)
|
||
|
||
while not app.need_exit():
|
||
x, y, pressed = ts.read()
|
||
if x > 0 and x < 100 and y > 0 and y < 100:
|
||
app.set_exit_flag(True)
|
||
|
||
menu_update(img) # 更新菜单
|
||
disp.show(img) # 屏幕显示
|
||
``` |
