hi i'm using gt911 and its worked fine. but when i use long time touch, after some time (ex 3 - 4 - 5 secend) ic don't send me interrupt until i release touch and then touch the screen.

i use this configuration of register:

uint8_t s_GT911_CfgParams[]={ //configVersion 0x00,0x98,0x03,0x26,0x02,0x01,0x0D,0x00,0x01,0x08, 0x1E,0x0F,0xB0,0x60,0x03,0x0F,0x00,0x00,0x00,0x00, 0x00,0x00,0x04,0x18,0x1A,0x1E,0x14,0x8B,0x2B,0x0E, 0x71,0x73,0xB2,0x04,0x00,0x00,0x00,0x01,0x02,0x1D, 0x00,0x01,0x00,0x00,0x00,0x03,0x64,0x32,0x00,0x00, 0x00,0x50,0xA0,0x94,0xD5,0x02,0x07,0x00,0x00,0x00, 0x9D,0x55,0x00,0x8D,0x62,0x00,0x80,0x71,0x00,0x74, 0x82,0x00,0x6B,0x95,0x00,0x6B,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x02,0x04,0x06,0x08,0x0A,0x0C,0x0E,0x10, 0x12,0x14,0x16,0x18,0x1A,0x1C,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x02,0x04,0x06,0x08,0x0A,0x0C,0x0F, 0x10,0x12,0x13,0x16,0x18,0x1C,0x1D,0x1E,0x1F,0x20, 0x21,0x22,0x24,0x26,0xFF,0xFF,0xFF,0xFF,0x00,0x00, 0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00, 0x00,0x00,0x00,0x00,0x67,0x01};

is there any way to detect long touch?
