RC522 SPI接口的51单片机程序例程(RC522 SPI)

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.)

Micrium_STM32L152-EVAL_uCOS-III STM32L系列的uCOS-III移植，官方Demo，很好，很强大 (Micrium_STM32L152-EVAL_uCOS-III STM32L series of uCOS-III transplant, the official Demo, very good, very strong)

说明：  STM32L053+AD8232简易的便携式心电采集蓝牙传输PCB(Stm32l053 + ad8232 simple portable ECG acquisition Bluetooth transmission PCB)

在远距离数据通信中，为了确保数据传输正确，必须才ＣＲＣ算法，本代码就是ＣＲＣ算法(In the long-range data communications, in order to ensure that data is correct, must be only CRC algorithms, the code is the CRC algorithm)

STM32无感FOC控制源码，适合新手学习FOC(BLDC CONTROL BASE STM32)

说明：  基于51单片机，芯片stc89c52,使用PCF8591ad转换器的源代码(Based on 51 MCU, chip stc89c52, using PCF8591ad converter source code)

rtthread，基于SD卡中的 Elm FatFS 文件系统，rt-thread的elmfat文件系统是一个开源的小型嵌入式文件系统。可以直接移植(rtthread, based on the SD card file system Elm FatFS)
