The circuit design of low-cost monochrome paperless reconrder based on LPC2134

In this paper, the circuit design of low-cost monochrome paperless recorder based on LPC2134 is introduced. The design fully tapped the chip＇s internal resources, such as using four-channel data acquisition channels, universal signal programmable input, optical isolation between channels using MOS. The hardware circuit is simple, less external circuitry, low cost After testing and field use, it is stable, high reliability and a cost-effective circuit design. A new platform is provided for the current paperless recorder hardware design.
