框架总软件

一、触摸屏编程

二、增加input代码

1.touchscreen.c

touchscreen.c

#include <input_manager.h>
#include <tslib.h>

static struct tsdev *g_ts;


static int TouchscreenGetInputEvent(PInputEvent ptInputEvent)
{
	struct ts_sample samp;
	int ret;
	
	ret = ts_read(g_ts, &samp, 1);
	if (ret != 1)
		return -1;

	ptInputEvent->iType		= INPUT_TYPE_TOUCH;
	ptInputEvent->iX 		= samp.x;
	ptInputEvent->iY 		= samp.y;
	ptInputEvent->iPressure = samp.pressure;
	ptInputEvent->tTime		= samp.tv;

	return 0;
}
static int TouchscreenDeviceInit(void)
{
	g_ts= ts_setup(NULL, 0);
	if (!g_ts)
	{
		printf("g_ts_setup err\n");
		return -1;
	}
	return 0;
}
static int TouchscreenDeviceExit(void)
{
	ts_close(g_ts);
	return 0;
}
struct InputDevice *ptNext;

static InputDevice g_tTouchscreenDev = {
	.name = "touchscreen",
	.GetInputEvent = TouchscreenGetInputEvent,
	.DeviceInit    = TouchscreenDeviceInit,
	.DeviceExit    = TouchscreenDeviceExit,
}

总结

TouchscreenGetInputEvent

TouchscreenDeviceInit 初始化

TouchscreenDeviceExit 退出

static InputDevice g_tTouchscreenDev 结构体
