用V3S的BSP，修改fex如下
[ctp_para]
ctp_used = 1
ctp_name = "tsc2007"
ctp_twi_id = 0
ctp_twi_addr = 0x90
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_int_port = port:PB02<6><default><default><default>
;ctp_int_port = port:PG04<6><default><default><default>
;ctp_wakeup = port:PG03<1><default><default><1>
重新编译下载后显示

不是没有加变量的问题，貌似是TWI驱动的问题，不知道BSP如何修改
