这个源码是利用STM32操作ATT7022E，并简单的读取各项基本参数的通讯例子。STM32使用R8T6，计量芯片是ATT7022E。例程中采用模拟SPI来对ATT7022E进行操作，里面的初始化、校表的寄存器操作均是根据ATT7022E的用户手册和应用笔记的最新寄存器操作进行。希望这个例子能对使用这款芯片做电力仪表的带来帮助。(This source is the use STM32 operating ATT7022E, and a simple example of the basic reading communication parameters. STM32 using R8T6, metering chip is ATT7022E. Analog SPI routines to manipulate ATT7022E, register operations inside the initialization, school tables are made in accordance ATT7022E user manuals and application notes for the latest register. I hope this example will bring help to use the chip to make electricity meters.)

说明：  TC275单片机基于autosar的bootloader工程代码(Bootloader engineering code of tc275 SCM based on AUTOSAR)

说明：  sd卡初始，由于SD卡使用SPI模式，并且是块读取(512Byte),所以需要单片机提供大于512的可用RAM，以供缓冲使用 这里可以选择STC89c52RD+、STC89C58RD+、STC89C516RD+，后缀RD+表明扩展RAM是1024字节，RC表明扩展RAM256字节(sd card original, because the SD card using SPI mode, and is a block read (512Byte), so they need the microcontroller to provide more than 512 of the available RAM, for buffer used here can choose STC89c52RD+, STC89C58RD+, STC89C516RD+, the suffix RD+ that extended RAM is 1024 bytes, RC that extended RAM256 byte)

STM8L052 的LCD段码驱动显示程序。STM8的LCD驱动器驱动比较复杂，没有规律，显示段码8，需要每位对应，本程序使用三个数组和很小的程序实现段码显示。减少了程序量，提高了效率。(LCD Segment drive STM8L052 display program. STM8 LCD driver drive more complex, there is no law, code display section 8, each corresponding to the needs, the program uses three arrays and procedures to achieve a small segment display. Reduction program, improving the efficiency.)
