TX-1BDS18B20

说明：  最新超低功耗,超高速 51单片机的资料.非常难得.(a new ultra-low power consumption,ultra high speed 51 signal-chip book.)

说明：  这篇文档描述了怎样使用STM32F101xx和STM32F103xx的直接对内存访问(DMA)控制器(This document describes how to use STM32F101xx and STM32F103xx direct memory access (DMA) controllers)

此程序上利用2051单片机产生逻辑信号，且信号可以任意设置(use of this procedure have 2051 microcontroller logic signals, which can be set up without signal)

区域中央空调市场调研报告，市场调研报告模板(Regional central air-conditioning market research report, market research report template)

说明：  转 VF算法控制三相无刷电机，开环控制，无传感器(VF controlled three-phase brushless motor) 包含FOC 核心算 clark park ipark svpwm IQ格式的计算，值得参考。只要设定电压与频率比就能让电机，属于开环控制，很好验证硬件与软件的程序。(VF controlled three-phase brushless motor is controlled by VF algorithm and open-loop control. The calculation of Clark Park Ipark SVPWM IQ format is included in VF controlled three-phase brush motor. As long as the voltage to frequency ratio is set, the motor belongs to open-loop control, which can verify the hardware and software program well.)

ARM程序，实现了SPI通信协议，可用于任何使用SPI通信协议的器件上，在LPC2103上测试成功。(ARM procedures realize the SPI communication protocol, can be used for any use of SPI communication protocol on the device, tested successfully in the LPC2103.)
