outdoor interactive touch screen.Made in the tube before the internal state unpowered chips it is random, so all of the infrared emission immediately after a power is not an ideal " 0 " state, there will be many branches are simultaneously illuminated infrared emission. This state causes the current of the infrared emitting tube to be too large, and the driving voltage in the entire system is severely pulled down, making the microprocessor chip unable to work normally. Therefore, it is necessary to use a large current power input to clear the infrared transmitting circuit after power-on. Through such processing, the chip can work normally. You only need to write 0 to the data end DS , and then you can clear the infrared transmitting circuit.
