ad7195   配置寄存器G0位不能修改

在这个帖子中,有工程师提到一些英文资料

 

我浏览了一遍

A Reference Design for High-Performance, Low-Cost Weigh Scales | Analog Devices

其中有几点不太明白的,希望ADI工程师能给予回复。

关于PCB layout

In this reference design, the ground plane is separated into analog- and digital sections.

参考设计中,并且把地层分割为模拟地和数字地,意思是:板卡需要设计为4层板,其中一层为模拟地,另一层为数字地,还是其他情况?

关于数字地和模拟地:

The GND pin of AD7799 should connect to the analog ground.

GND引脚接到模拟地?

关于AVDD DVDD,

两个电源中间加个铁氧体磁珠?

 

 

最重要的是

Hardware and Software

The AD7799/ADuC847 weigh-scale reference design can also be interfaced to any PC, using an RS-232 interface. This allows the user to save and process data when evaluating the system. The hardware and software specifications of the reference design are freely available, including source code, schematic and PCB Gerber files. Please contact the authors for more information.

 

 

硬件软件设计均可以免费获取,目前已经买了一块AD7190评估板EVAL-AD7190EBZ,板卡上是一颗C8051的MCU,不知道source code 包含不包含MCU源码。联系作者可以得到更多信息?

 

 

下面提供了两个作者

 

 

作者一:

 

 

Colm Slattery is an applications engineer in the I&I segment at Analog Devices. His first role in ADI was as a Test Development Engineer. He has also spent 3 years based in Shanghai, China, supporting field activities for the precision Converter group. Prior to his role in the I&I group, Colm was a product line applications engineer in the DAC group.

 

 

作者二:

 

 

Mariah Nie is the manager of the China Applications Support Team. She has worked at ADI for five years and is responsible for supporting horizontal analog products across China. Mariah graduated in 2003 from Beijing Institute of Technology with a master’s degree in electrical engineering.

 

 

目前在使用AD7190,我想了解AD7190的相关资料如何获取,主要是source code 和PCB design file
