ViewChr 程序使用说明：
本程序可方便浏览和调用 Hzk16（16*16中文点阵字库）和Asc16（8*16中文点阵字库）内容。
通过滚动条对字库进行浏览，通过文本框可以输入中文字符获取其字体点阵，按"Add chr.asm"键或回车键可以将其字体点阵16进制数据转换成对应的ASCI码追加到CHR.ASM文件中。在显示文字区域双击可切换网格显示开关状态。
如果你要做点阵屏显示中文字体程序，那这个程序将是你的好帮手。
(备注:ASCII码文件CHR.ASM的取字方向同字库Hzk16和Asc16)

周立功D12开发板中带的WINDOWS XP驱动程序，在编译后会出现USB设备不能正常工作. 以下是修改的代码,修改后可以正常工作. 在d12.c和Ioctl.c中, 将+256去掉,这个会引去枚举设备时,设备描述符的长度不对,修改后: siz = sizeof(USB_CONFIGURATION_DESCRIPTOR) 在d12.c中的D12_SelectInterface函数中, 设备查询完接口后有一段代码,也会引起驱动返回不对,需要屏蔽下面的代码 // Retrieve the selected Configuration and Interface 修改上面两处后,USB可以正常使用了. -weeks D12 development board, who were brought to the Windows XP drivers, the compiler will happen after the USB device not working properly. Following is the revised code, revised after normal work. In d12.c and Ioctl.c, 256 will be removed, this will generate to Enumerate equipment located descriptors up the length wrong, the revised : not = sizeof (USB_CONFIGURATION_DESCRIPTOR) in the D12_SelectInterface d12.c function, equipment End interface for a period after the code can also lead to wrong drivers need to shield the following code// Retrieve the selected Configuration Interface and the above two changes, USB can use the normal.

BLDC 矢量控制
资源描述This application note shows how to control a permanent
magnet synchronous motor (PMSM) with the sensorless
field-oriented control (FOC) algorithm, using an ARM®
Cortex®-M0-based PSoC 4 device.
The FOC algorithm is frequently used in motor control
applications because it allows motors to operate with less
noise and more stable torque output than other algorithms.
Sensorless FOC adds the advantage of reducing the cost
due to the absence of rotor position sensors. Sensorless
FOC is used in many applications including consumer (air
conditioner, refrigerator), industrial (blower, pump), and
commercial (elevator, escalator) products.
