Eye axis control integrated circuit

Abstract

The invention discloses an eye axis control integrated circuit which is installed on a circuit board. The eye axis control integrated circuit comprises a GPRS wireless data transmission module, a DC-DC power management module, an MCU control circuit module, a liquid crystal display circuit module, a light source control circuit module and a touch detection circuit module, wherein the GPRS wirelessdata transmission module is positioned on the right side of the circuit board; a radio frequency part of the GPRS wireless data transmission module is isolated by a metal shielding cover; the DC-DC power supply management module adopts a voltage regulator; the MCU control circuit module adopts a standard RISC processor based on an ARMv7-M architecture; and the light source control circuit moduleadopts red light with the wavelength of 650 nm. The eye axis control integrated circuit realizes integration of an eye axis control circuit, is high in integration degree, is simple in structure, integrates an SDR video memory function, an audio MP3 decoding function and a JPEG picture decoding function internally, and has the advantages of high anti-interference performance, long data storage time and higher safety.
