I’m trying to interface my BBB with a 4,3’’ capacitive LCD (NHD-4.4-480272EF-ATXL-CTP) using LCD4 cape that is hardaware prapared to connect capacitive LCD with the I2C interface.
When boot my BBB, it detects LCD4 cape through the EEprom memory and it load coorectly BB-BONE-LCD4-A001.dtbo overlay binariy file that contains the configuration for the resistive Touch LCD. Now i have to modify that file to describe the interface of my capacitive LCD that differs only for the i2c interface to communicate touch points.
I have found the kernel driver that communicate with the i2c controller (FT5x06) of the LCD, it is place in /lib/modules/3.8.13/kernel/drive/input/touchscreen/edt-ft5x06.ko but before I have to load a correct DTS fbut i can’t find it.
Can someone help me to resolve this problem?
