32*64摇摇棒，使用51MCU，8KROM，可以储存8*1024/32=256个16*16的汉字，减去程序控件，大概可以储存200个汉字。采用外部中断控制摇摆方向，通过一定的延时来平衡扫描时间和摆动时间。外部中断触发信号来自硬件水银开关的来回通断。-32* 64 shook his stick, use 51MCU, 8KROM, can store 8* 1024/32 = 256 16* 16 characters, minus the program control, can store about 200 characters. External interrupt control swing direction, by a certain delay to balance the scan time and swing time. External trigger signal from the hardware interrupt switch back and forth off the mercury.
