hs code for touch screen display.This part is mainly used by the microprocessor to address each ADS7830 through the I 2 C bus to complete the amplification of the light intensity signals of 165 infrared receivers, analog-to-digital conversion and return the value to the microprocessor. Made in 165 branched need infrared receiver 21 is sheet ADS7830 addressing is done, the microprocessor is only 2 th the I 2 C interfaces it is necessary to extend the I 2 C interface. This selection of core 74HC4051 , with two address lines extend to obtain . 5 th the I 2 C access port, selected through five sets of infrared receiving module. In this way, the microprocessor can address each infrared receiver one by one through the I 2 C bus. Serial port communication section is composed of 19 feet, the first 21Feet to complete. They are the signals TxDO and RxDO on the serial bus, which are used to transmit the processed touch position information to the host. Circuit schematic of FIG as shown below:
