Title: a20 lime2-4gb / Capacitive Touch Not working
Post by: AnkyB on May 15, 2017, 03:11:11 PM
Hi,

I am using Newhaven NHD-7.0-800480EF-ASXN#-CTP (Capacitive touch) LCD Touchscreen with A20 Lime2-4gb ( latest debain jessie8 image).
LCD display is working properly but touch is not working. Touch connections are made on TWI0 and /INT pin on pin PH0 of A20 board.

I have tried following changes in script.bin considering TWI0 connections,but still not getting touch working.

[ctp_para]
ctp_used = 1
ctp_name = "ft5x_ts"
ctp_twi_id = 0
ctp_twi_addr = 0x38
ctp_screen_max_x = 800
ctp_screen_max_y = 480
ctp_revert_x_flag = 0
ctp_revert_y_flag = 0
ctp_exchange_x_y_flag = 1
ctp_firm = 1
ctp_int_port = port:PH0<6><default><default><default>
ctp_wakeup = port:PI0<1><default><default><default>

[ctp_list_para]
ctp_det_used = 1
ft5x_ts = 1
gt82x = 0
gslX680 = 0
gt9xx_ts = 0
gt811 = 0

and also
twi0_used =1 is set.


Can anyone help me how can I resolve this issue?


Thank you in advance

Anky
