摘　　要：采用点阵图形液晶模块的信号曲线显示,由AT89S52、TLC2543和128×64点阵图形液晶模块组成,其AT89S52的P2.4～P2.7口分别与TLC2543的CS、DOUT、DIN和CLK端连接。模块软件利用P2.5口向TLC2543写控制字,选择A/D通道并将转换结果通过P2.4口读到AT89S52的某个寄存器中,再利用P1.0～P1.7口和P3.2～P3.7口控制点阵图形液晶模块将A/D转换结果从液晶屏幕上显示。The display of signal curve is composed of an AT89S52, a TLC2543 and a 128×64 pixels graphics LCD module. The ports from P2.4 to P2.7 of AT89S52 are linked to the ports of CS, DOUT, DIN, and CLK, respectively. The control word is written into TLC2543 Via P2.5 and sent to one register of AT89S52 via P2.4 after being converted by A/D conversion. Then, it will be controlled to display on the LCD module via the ports from P1.0 to P1.7 and the ports from P3.2 to P3.7.
