三星x609手机升级文件,修改了内置铃声

用stm32做的GPS+GPRS驱动,可以用在物联网行业,实实在在的源代码,非常有用,修修改改就可以成你的代码了...

用430编写的SD卡读写程序，希望对大家有用。-Prepared with the SD card reader 430 procedures in the hope for all of us.

一个关于s3c2440开发版电路图,值得参考-a development version of s3c2440 circuit, it is worth reference

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)

这是本人写的HT1621显示驱动！是用PICC语言写的，比较好，反正大家用的高兴就写信跟我说一声哟！-HT1621 display driver.

这是一个复数乘法器，相信对经常从事dsp信号处理的人士有帮助，该乘法器采用先进的dspbuilder进行建模，既简洁又实用。-This is a complex multiplier, believe that engaging in regular dsp signal processing to help those who have the multiplier dspbuilder the use of advanced modeling, both simple and practical.
