75 inch interactive touch screen.It made in ADS7830 with the I 2 C , so that the interface can be through the I 2 C communication with the microprocessor bus. At the same time, it has 8 sampling channels , that is, each chip can sample light intensity signals on 8 infrared receiver tubes and perform analog-to-digital conversion. This can effectively reduce the number of drive chip most, from the reduced costs. In addition, I 2 C bus communication is accomplished by addressing the address of the I 2 C device . Therefore, the correctness of the address of each channel of each infrared receiving tube will affect the light intensity of the entire infrared receiving circuit. Acquisition of signals. ADS7830 address as provided below:
