基于stm32f407的手写识别程序，亲测可用(Handwriting recognition program based on stm32f407)

神经网络中的权值、阈值以及中间变量很多，但是单片机的程序区和数据区的容量都是有限的。89C52程序区为8K字节，数据区为256K字节。由于探测器受体积限制应尽量避免外扩存储器，所以在实现计算时，要将权值和阈值写成立即数形式减少资源占用。(Neural network weights, threshold and intermediate variables, but procedures for single-chip area and the volume of data are limited. 89C52 process area for 8K byte, 256K-byte data area. As the detector by the volume limit should be avoided as far as possible outside the extended memory, so in the realization of the calculation, the right to the threshold value and written in the form of an immediate reduction in the number of occupied resources.)

说明：  本文从硬件出发，系统地讲解了文件系统实现的原理，内容详细全面而有条理(Starting from the hardware, this paper systematically explains the principle of file system implementation. The content is detailed, comprehensive and orderly.)

stm32f103zet6 KEIL MDK 包括功能 3.5寸TFT彩屏 fsmc接口通讯； 电阻触摸 xpt2046 采用SPI通讯 AD数据采集 DMA传输 2000点，以及平滑滤波；DA输出； (Stm32f103zet6 including 3.5-inch TFT color screen fsmc interface communication Resistive touch xpt2046 using SPI communication AD data acquisition DMA transfer 2000 points, and smoothing filter DA output )

单片机串口接收缓存队列的简单实现，由C语言实现，性能稳定，移植方便可靠！(Microcontroller serial port to receive buffer queue to achieve a simple, achieved by the C language, stable performance, reliable and convenient transplantation! )

超精简的读写u盘程序，只有180行，可生成文件系统，估计再没有比这更短的程序了把？(Super-streamlined procedures to read and write u disk, only 180 lines, can generate the file system, it is estimated that more There is nothing short of the procedures?)

说明：  实现modbus 客户端的给功能，实现tcp通讯(Implementing the function of Modbus client,Realizing TCP communication)
