比RS485更精准的can接受通信，基于128单片机开发，对于有志于128通信方面的读者有一定参考价值 (More accurate than the RS485 can accept the communication, based on 128 microcontroller development, communications for aspiring 128 readers have a certain reference value)

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)
