blcd-220V
本方案是基于富士通高可靠性单片机开发的锂电池电动螺丝刀，采用直流无刷电机作为核心，配合方波驱动以及闭环控制技术，实现电动工具的可靠运行。
技术参数
1）采用日本富士通MCU，性能稳定，抗干扰强，高可靠性；
2）直流18V输入（可兼容不同锂电池10V—36V）；
3）三相霍尔直流无刷电机驱动，转速高达25000转/分；
4）采用德国英飞凌高性能MOS/IGBT，驱动功率高达800W；
5）高亮LED照明，工作时点亮，不工作时自动熄灭；
6）采用智能控制技术实现待机（不工作时）功耗为 0 消耗；
7）通过软件实现软启动，启动时间可调整，瞬间（1S）达最高速；
8）具有过流保护、堵转保护、过压欠压保护；
9）带速度设置按键、正反转按键、调速开关；
(The program is based on the Fujitsu MCU development of high reliability lithium battery electric screwdriver, brushless DC motor as the core, with the square wave drive and closed-loop control technology, power tools for reliable operation.)

led-clock
The LED clock consists of 60 LEDs which are placed circular around a common analog clock. The LEDs are used to display the seconds. Essential part of this circuit is the LED driver MAX7219 from Maxim. A datasheet is available on Maxim s homepage. The clock is controlled by the microcontroller AT89C2051 from Atmel. This microcontroller is clocked at a frequency of 12 MHz from which results a time base of 1 microsecond. Via software dividers one clock impulse per second is generated which is used for updating the LED display.
