读取各项基本参数的通讯例子 STM32 7022E
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.)
