/*
* The sun4i-ts controller is capable of detecting a second touch, but when a
* second touch is present then the accuracy becomes so bad the reported touch
* location is not useable.
*
* The original android driver contains some complicated heuristics using the
* aprox. distance between the 2 touches to see if the user is making a pinch
* open / close movement, and then reports emulated multi-touch events around
* the last touch coordinate (as the dual-touch coordinates are worthless).
*
* These kinds of heuristics are just asking for trouble (and don't belong
* in the kernel). So this driver offers straight forward, reliable single
* touch functionality only.
*
* s.a. A20 User Manual "1.15 TP" (Documentation/arm/sunxi/README)
* (looks like the description in the A20 User Manual v1.3 is better
* than the one in the A10 User Manual v.1.5)

嗨,大家好。 如何将内置电阻式触摸屏驱动程序(RTP)F1C100S移植到Rtthread littlevGL7.1。

参考XBOOT的裸机程序就可以了

你好.请帮助我提供端口代码。
使用rt_hw_interrupt_install函数而不是request_irq函数,或者使用其他什么输入参数?
抱歉,我是否在新的RT-THREAD中这样问.

#define TOUCHPANEL_INTERRUPT (20) rt_hw_interrupt_install(TOUCHPANEL_INTERRUPT, you_touch_handle, param, "touch");
你好. 亲爱的朋友aozima 感谢您解释参数结构并编写you_touch_handle函数吗?
