I am actually trying to interface the Linux Touchscreen developed by Reach Technology Inc., which uses the MCIMX6S5DVM10AB processor via I2C. When I contacted the Reach Technical support team, they said that the touchscreen is made with the intention to use as a Master and it cannot be used as a slave. But in real, I want to interface three of these screens with an external Controller which is the Master I2C device and all the screens should be slaves to it. Please reply with suggestions to convert the Master to slave. Thanks in advance.
