一种电机调速控制方法，单片机：P89LPC9401.包括主要是对可控硅移相触发，程序主要包括利用P89LPC9401的FLASH,作数据存储器用的读写（不多见的思路）可控硅的移相触发程序。以及PCF8576笔画液晶屏的驱动程序-A motor speed control method, MCU: P89LPC9401. Including key is to trigger the SCR phase-shift, the program includes the use of P89LPC94

vhdl,Digital phase modulation is also known as phase shift keying, 2DPSK is binary differential phase shift keying, is a kind of digital phase modulation. Digital phase modulation using carrier phase change to transmit digital signal, usually can be
