请问电阻触摸屏，点击按钮有时会触发两次的问题

yxy633

参考正点原子imx6ull移植了QT5.12和tslib，屏幕触摸屏用8寸电阻屏，跑QT的APP点击按钮有时会连续触发两次，可能是哪里的问题呢请教各位大神。

设备树配置如下

1. 
   
2.          tsc2046 {
   
3.   compatible = "ti,tsc2046";
   
4.   reg = <0>;
   
5.   spi-max-frequency = <1000000>;
   
6.   pinctrl-names ="default";
   
7.   pinctrl-0 = <&pinctrl_tsc2046_pendown>;
   
8.   interrupt-parent = <&gpio1>;
   
9.   interrupts = <9 0>;
   
10.   pendown-gpio = <&gpio1 9 0>;
    
11.   ti,x-min = /bits/ 16 <0>;
    
12.   ti,x-max = /bits/ 16 <0>;
    
13.   ti,y-min = /bits/ 16 <0>;
    
14.   ti,y-max = /bits/ 16 <0>;
    
15. 
    
16.   ti,pressure-max = /bits/ 16 <0>;
    
17.   ti,x-plat-ohms = /bits/ 16 <0>;
    
18. 
    
19. 
    
20.         ti,debounce-max = /bits/ 16 <50>; /*消抖采样次数最大值，采样消抖超过该值，忽略本次 */
    
21.         ti,debounce-tol = /bits/ 16 <50>; /*正负误差范围 */
    
22.         ti,debounce-rep = /bits/ 16 <0>;
    
23. 
    
24.         /*ti,pendown-gpio-debounce = /bits/ 32 <10>;*/
    
25. 
    
26.    /*ti,swap-xy;*/
    
27.   linux,wakeup;
    
28. };
