TM7711 是应用于电子秤低频测量的单通道模拟前端。 该器件可以接受直接来自传感器的低电平的 输入信号，然后产生串行的数字输出。利用 Σ-Δ 转换技术实现了 24 位无丢失代码性能。通过选定的输 入信号被送到一个基于模拟调制器的增益可编程专用前端。 片内数字滤波器处理调制器的输出信号， 通 过通信口发命令可调节滤波器的截止点和输出更新速率，从而对数字滤波器的第一个陷波进行编程。 TM7711 只需 2.6~5.5V 单电源供电。TM7711 是全差分模拟输入，带有一个基准输入。 TM7711 是一款用于高精度电子秤系统的理想产品，由于采用特殊的结构确保器件具有极低功耗， 并且内建有掉电模式以减少待机功耗。该芯片还具有集成度高、响应速度快、抗干扰强等优点，可以大 大降低电子秤系统的整机成本，提高整机系统的性能和可靠性。(TM7711 is used in electronic scales measuring the low-frequency single-channel analog front-end. The device can accept a low level directly the sensor Input signal, and then generates a serial digital output. Use Σ-Δ converter technology to achieve 24-bit no missing code performance. Via the selected output The signal is fed to an analog modulator based on a dedicated front-end programmable gain. Chip digital filter processing modulator output signal through Send commands over the communication port can adjust the filter cutoff and output update rate, and thus the first notch digital filter can be programmed. TM7711 only 2.6 ~ 5.5V single power supply. TM7711 is a fully differential analog input with a reference input. TM7711 is an ideal product for high-precision electronic scale systems, the use of a special structure to ensure that the device has a very low power consumption, And built-in power-down mode to reduce standby power consumption. The chip also features high integra)

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.)
