Hello, I’m working with a Wi-iMX53 and I connected a display with VGA connector and works. This display has a 4 wired touch screen and I want to cennect It but Idont know how. I was reading a lot and I read that the Wi-iMX53 has a DA9053 that is connect with a parallel LCD. I thinking in connect my touch screen to those DA9053 pins, but I dont know if that is dangerous or what. Can you helpme? Thanks. ---

you have to figure out what interface your touchscreen is using (SPI? I2C?) and then connect it to the appropriate interface on the board, matching the pins and signals. ---

Hi, thanks for response. I just have a touch screen sensor without controller with 4 wires (+x, -x, +y, -y) and I want to use the pmic controller of the Wi-iMX53 connectcore, and my question is where or how I connect It or if is possible connect It directly . The parallel LCD connector is connected to +x, -x, +y and -y pins of the pmic controller. My monitor is VGA. Is it possible connect It directly to those pins? ---

yes, looks like it should work
