8051模拟I2C，I2C单字节读写和多字节读写

这是R、C、L的全国电子设计，从07-2009-This is the R, C, L of the national electronic design, from 07-2009

附件程序是我用DSP2812开发的无刷直流电机控制程序，程序是在TI公司的BLDC3_1软件的基础上构造的，实现了无刷直流电机的速度环PID控制，效果可以。 其中，无刷直流电机是有HALL传感器的系统，所以在转速测量上还需要进一步的改进（如果要求精确的话）。电机是24V3000rpm～～～；驱动板是类似TI公司的DMC1500？板卡，所以可以参考它的说明（只针对信号的连接的参考）-Annex I use the procedure is the development of the DSP2812 brushless DC motor control procedures, TI is in the process of BLDC3_1 software companies on the basis of the structure, Implementation of the brushless DC motor velocity loop PID control, the effect can be. Among them, brushless DC motor are HALL sensor system So speed measurements need further improvements (if the precise words). Motor V3000rpm is 24 ~ ~ ~; Market-driven companies like TI DMC1500? Card, we can refer to it (only signal against a reference link)
