hi,
I am trying to interface a 7" tft display with the imx6q sabrelite board. have configured the yocto for the gui.Can anybody suggest or provide some sample progams about how to configure when we touch a particular point in the display? The interface is I2C
Hi,
The ETM0700H3DH6 does not seem supported by the kernel by default. Therefore you will have to add the timings to the lcdif_modedb array:
linux-imx6/mxc_lcdif.c at boundary-imx_3.14.28_1.0.0_ga · boundarydevices/linux-imx6 · GitHub
Then you will need to modify the device tree accordingly:
I assumed your kernel version was 3.14.28, Ubuntu 14.04 being the OS version which can run on any kernel version.
Finally for the touch screen controller, since this is a regular mcu, it all depends on the firmware flashed to it, you'll most likely have to create a custom driver for it.
Regards,
Gary
