设计一个液晶显示驱动电路，要求能够显示至少两个周期的三角波形，并显示“T=30ms”的字样。-The design of a liquid crystal display driver circuit, the requirements are able to show that at least two cycles of the triangular waveform, and display T = 30ms message.

无字库液晶驱动程序,画点，画线 显示波形-No character LCD driver, painting, drawing lines Waveform display

基于51单片机的波形发生器，波形用12864液晶显示，可以波形切换，波形频率、空占比可调-51 microcontroller-based waveform generator, 12864 LCD waveforms can waveform switching waveform frequency, accounting for adjustable air

能在液晶上显示文字，画各种线条，制作曲线，在相应硬件的支持下还能显示心电信号的波形等(can show the word and draw the lines or circle in screen)
