static struct ads7846_platform_data ads_info = {
.model = 7843,
.x_min = 150, .x_max = 3830,
.y_min = 190, .y_max = 3830,
.vref_delay_usecs = 100,
.x_plate_ohms = 450,
.y_plate_ohms = 250,//250,
.pressure_max = 15000,
.debounce_max = 1,
.debounce_rep = 0,
.debounce_tol = 100,
.get_pendown_state = ads7843_pendown_state,
};
请教在这个结构体中,各个参数是什么含义?那些是应该从触摸屏硬件手册中查到的?
我见到有人把 .x_min = 150, .x_max = 3830,
.y_min = 190, .y_max = 3830,注释掉,不知道如何确定x y大小
