这是针对XC878单片机的各模块的程序，包含有LCD，UART，AD，DA以及七段数码管等。适合移植和学习。(It is for each module XC878 microcontroller program includes LCD, UART, AD, DA, and seven-segment digital tubes. Suitable for transplant and learning.)

使用485向外发送0-255的数字。 若开发板的485接收到256个字节数据，会把数据以16进制形式打印出来。(Use 485 to send out 0-255 digits. If 485 of the development board receives 256 byte data, the data will be printed in 16 form.)

1602LCD工作于四位模式实时显示当前时间，本程序液晶数据端口仅使用了四只引脚,实现日期时间的实时显示.(1602LCD works in four modes display the current time, the program uses only the LCD data port four pins, date and time of the real-time display.)

说明：  MAX7221控制数码管动态显示的单片机C语言源程序，对初学者很有帮助(The MAX7221 Control single-chip digital control dynamic display C language source code, useful for beginners)

说明：  stm32汉字输入用的字库，可写汉字，亲自测试可以写各种字体(Stm32 Chinese Character Input Library, Writable Chinese Characters)

基于STM32F407的LED音乐频谱，AD+DMA采集音乐信号，利用FFT运算得出音乐频谱，通过10*8的LED点阵显示的音乐频谱单片机代码(Based on the LED music spectrum of STM32F407, AD+DMA collects the music signal, obtains the music spectrum by FFT operation, and displays the music spectrum code by 10*8 LED dot matrix.)

stm32f103c8t6模板，基于ST固件库3.5，包含常用基本配置(Stm32f103c8t6 template, based on ST firmware library 3.5, contains common basic configuration)

说明：  激光雷达测距，树莓派识别二维码，路径规划，定向搬运(Laser radar ranging, raspberry pie recognition two-dimensional code, path planning, directional handling)

PMbus中,可以将query解析,并具有修改，添加，删除等功能，以及生成code.(for pmbus query)
