(续上期)5DALI从动部分功能和硬件设计本设计的DALI从动器的硬件总体框图如图7所示。图7DALI从动器的硬件总体框图从动器同样包含了硬件和软件2部分。单片机PIC16F628A接收主控制器通过DALI线传送过来的命令和数据。如果命令是控制类指令,程序解释命令的代码,控制PIC16F628A的相应引脚输出正确的信号,通过其外围电路传送给镇流器。之
(Continued) 5DALI Slave Function and Hardware Design The hardware block diagram of the DALI slave designed in this section is shown in Figure 7. Figure 7DALI slave hardware overall block diagram Slave also includes hardware and software 2 parts. The PIC16F628A microcontroller receives commands and data from the host controller over the DALI line. If the command is a control class instruction, the program interprets the command code, controls the corresponding pin of the PIC16F628A to output the correct signal, and sends it to the ballast through its peripheral circuitry.
